The limitations of conventional and current solar cells include high production cost, low operating efficiency and durability, and many cells rely on toxic and scarce materials. Northwestern University researchers have developed a new solar cell that, in principle, will minimize all of these solar energy technology limitations.
In particular, the device is the first to solve the problem of the Grätzel cell, a promising low-cost and environmentally friendly solar cell with a significant disadvantage: it leaks. The dye-sensitized cell's electrolyte is made of an organic liquid, which can leak and corrode the solar cell itself.
The Northwestern cell exhibits the highest conversion efficiency (approximately 10.2 percent) so far reported for a solid-state solar cell equipped with a dye sensitizer. This value is close to the highest reported performance for a Grätzel cell, approximately 11 to 12 percent. (Conventional solar cells made from highly purified silicon can convert roughly 20 percent of incoming sunlight.)
Despite the fact that solar panels are quickly becoming a commodity — cheap and uniform — it looks like investors are still willing to put a small amount of funding into the next-generation of solar equipment. Three startup solar makers have raised funds over the past week or so — two that make concentrating solar technology and one that makes crystalline silicon solar cells.
Last week Solexel, which uses silicon gas to make solar wafers, closed on $25 million in funding, according to a filing. Bloomberg reported on the deal and said that the funds would be used to build a pilot plant in California, which would be a testing ground for a larger commercial plant in Malaysia. Solar panel maker SunPower participated in the round, as did venture investors Kleiner Perkins, Technology Partners and DAG Ventures, reported Bloomberg.
Commerce Preliminarily Finds Dumping of Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled into Modules from the People's Republic of China
On May 17, 2012, the Department of Commerce (Commerce) announced its affirmative preliminary determination in the antidumping duty (AD) investigation of imports of crystalline silicon photovoltaic cells, whether or not assembled into modules (solar cells) from the People’s Republic of China (China).
For the purpose of AD investigations, dumping occurs when a foreign company sells a product in the United States at less than fair value.
Commerce preliminarily determined that Chinese producers/exporters sold solar cells in the United States at dumping margins ranging from 31.14 percent to 249.96 percent.
Solar power from space could be a valuable source of renewable energy, thanks to an innovative research.
Researchers at the University of Strathclyde, Glasgow, have already tested equipment that would provide a platform for solar panels to collect the energy and allow it to be transferred back to earth through microwaves or lasers.
This unique development would provide a reliable source of power and allow valuable energy to be sent to remote areas in the world, providing power to disaster zones or outlying areas that are difficult to reach by traditional means.
"Space provides a fantastic source for collecting solar power and we have the advantage of being able to gather it regardless of the time of the day or indeed the weather conditions," said Massimiliano Vasile, mechanical and aerospace engineer at Strathclyde, who is leading the research, according to a university statement.
Seven months after a trade investigation was launched, American solar companies and Chinese solar manufacturers will finally get a clear picture of the challenges ahead.
SolarWorld’s American operation led the filing of the complaint in October, making the case that Chinese manufacturers were getting an unfair level of subsidies from their government and they were then illegally dumping those products into the American market. The first phase of the ruling came down in March, and in that the Department of Commerce found an illegal level of subsidies. However, it preliminarily set the tariffs at between 2.9 and 4.73 percent.
A determination on the second of the two tariffs is set to be made on May 16 and announced on May 17. The history of international trade disputes suggests that the anti-dumping tariff, if one is set, is generally higher than the countervailing duty that measures the level of subsidies.
There are few places in the world where the opportunity for solar power is more blindingly obvious than India. There are also few industries where the possibility of collaboration between India and the United States is more tantalizing.
But while India’s solar industry is finally taking off, massive hurdles must be overcome before it can make a meaningful contribution to the country’s rapidly growing power needs, experts and business leaders say.
“India is a very important market for the solar industry, one of the top three markets worldwide,” said Jayesh Goyal of California-based concentrated solar power technology provider Areva Solar. “The general view is that India will reach the 3 percent target before 2022.”
The logic for the Indian solar sector appears almost irrefutable.
Turanor PlanetSolar, a futuristic-looking 100-foot catamaran, on Friday became the first vessel to have circumnavigated the planet exclusively on power generated by the sun. The voyage, which began and ended in Monaco, lasted 19-plus months and included layovers in 28 countries, which were designed to promote the importance of solar energy.
Traveling on an equatorial route to take advantage of abundant sunshine, Turanor PlanetSolar covered more than 37,000 miles and set multiple Guinness World Records. The five-man crew enjoyed stops in such destinations as Tangier, Miami, Cancun, the Galapagos Islands, French Polynesia, Brisbane, Hong Kong, Singapore, Bombay, Abu Dhabi and Doha.
A new independent research report released today by the Howard H. Baker Jr. Center for Public Policy at the University of Tennessee, Knoxville, found that solar energy is following the same path to commercialization as other traditional energy sources spurred by federal incentives. The study, titled "Assessment of Incentives and Employment Impacts of Solar Industry Deployment," also estimates that the U.S. solar industry could employ hundreds of thousands of Americans by the end of the decade.
Like oil, coal, natural gas, nuclear, and all other traditional energy sources, the Baker Center finds, solar has received support from the federal government to promote its usage in order to drive our economy. In fact, according to the report, diffusion of solar energy technology in the energy markets is very similar to the paths that many American industries have traveled to become mainstream. Unlike more mature technologies, however, that continue to receive subsidies, solar energy is currently in a very early phase of its growth trajectory.
Despite the series of withdrawals of greentech IPOs this month, solar rooftop installer SolarCity announced on Monday that it is planning for an IPO. The company says it filed its IPO registration on April 26, and is waiting for the documents to be reviewed and approved by the SEC.
A SolarCity IPO has been an open secret for the past few months and a report in Bloomberg in February said that an IPO could value SolarCity at more than $1.5 billion. Back in February SolarCity also raised $85 million from investors like Silver Lake Kraftwerk to expand its rapidly growing solar rooftop empire. Overall, SolarCity has raised just over $200 million in venture capital, company spokesman Jonathan Bass told us back in February.
Donald Trump swept into Scotland's parliament on Wednesday to demand the country end plans for an offshore wind farm he fears will spoil the view at his exclusive new $1.2-billion golf resort.
In a typically blunt display, the property tycoon told an inquiry into renewable energy to stop the wind power efforts in the country's north.
"Scotland, if you pursue this policy of these monstrous turbines, Scotland will go broke," he said. "They are ugly, they are noisy and they are dangerous. If Scotland does this, Scotland will be in serious trouble and will lose tourism to places like Ireland, and they are laughing at us."
When challenged to produce hard evidence about his claims on the negative impact of turbines, Trump said: "I am the evidence, I am a world-class expert in tourism."
The public gallery burst into laughter.
This project has been developed by Gujarat State Electricity Corporation Limited (GSECL), with full support from Sardar Sarovar Narmada Nigam Limited (SSNNL) which is the nodal agency behind construction of the Naramda canal that brought agricultural prosperity to the State. The engineering, procurement and construction contract for the project has been awarded to Sun Edison, a subsidiary of US-based global solar energy player, MEMC. The 750 metre stretch of the canal will generate 1.6 million units of clean electricity per year, as well as prevent evaporation of 900,000 litres of water per year from the canal.
Today, Gujarat has about 458 kilometres of open main canal, while the total canal length including sub-branches is about 19,000 kilometres; the final aim of SSNNL is to construct a total of 85,000 kilometres of canal network. Assuming a utilization of only 10% of the existing canal network of 19,000 kilometres, it is estimated that 2,200 megawatts of solar power generating capacity can be installed. This implies that 11,000 acres of land which would otherwise be needed to site solar panels as well as 20 billion litres of water per year can be potentially conserved.
The outlook for US wind power growth is cloudy and negative with the wind production tax credit (PTC) due to expire at year-end. The wind power forecast for 2012 is decidedly better north of the US border, in Canada, however. Canada’s wind power market should experience another year of record-setting growth in 2012, with the addition of some 1,500 MW of additional capacity, according to a Canadian Wind Energy Association (CanWEA) study released at the Global Wind Energy Council (GWEC) annual conference in Copenhagen.
Canada’s wind energy industry enjoyed a record year in 2011, installing around 1,267 MW of new capacity, an investment of $3.1 billion that created some 13,000 person-years of employment. That ranks 6th globally with a total wind energy capacity of 5,403 MW, enough to power more than 1.2 million homes, according to CanWEA and the GWEC’s 2011 annual industry reports.
Data centers guzzle down 2% of the electric grid’s capacity and run up $2 billion worth of monthly utility bills. Furthermore, it’s estimated that by 2020, CO2 emissions from data centers will top the emissions by the airline industry. How do we get the cloud under control?
One solution might be improving the efficiency in how data centers draw electricity in from the grid. A recent post from GE Reports takes a look at how 99% of this electricity could be pulled in more efficiently by bypassing ‘filters’ when they’re not absolutely necessary.
If all data centers (‘the cloud’) did this, we’d be able to save 4,000 megawatts of electricity worth more than $3 billion per year.
The U.S. wind industry installed 6,816 megawatts (MW) in 2011, 31 percent higher than 2010, for a total
of 46,916 MW installed to date, the industry's trade group said in a release Thursday.
Setting the stage for a strong 2012, the American Wind Energy Association (AWEA) also said there were more than 8,300 MW of wind power under construction across the United States.
The nation has about one million megawatts of generating capacity with about 400,000 MW coming from natural gas burning plants, 300,000 MW from coal, 100,000 MW from nuclear, 80,000 MW from hydropower, 50,000 MW from oil and the rest mostly from wind and other renewables.
One megawatt powers about 1,000 homes.
Wind and natural gas are the two largest sources of new generating capacity in the United States. Wind has provided about 35 percent of new U.S. power capacity over the past five years, AWEA said.
