Sharp has developed solar cells that match the concentrator solar cell efficiency world record set by Solar Junction last year. The technology’s staggering 43.5% efficiency from a triple-junction compound solar cell is 1.2% higher than the efficiency of the cells holding the record before March of 2011 (when Solar Junction busted that record). The conversion efficiency was actually confirmed by the Fraunhofer Institute for Solar Energy in April 2012 (for some reason, these companies and researchers don’t let us know about the new records for months sometimes). “Compound solar cells utilize photo-absorption layers made from compounds consisting of two or more elements, such as indium and gallium,” Sharp writes. “The basic structure of this latest triple-junction compound solar cell uses Sharp’s proprietary technology that enables efficient stacking of the three photo-absorption layers, with InGaAs (indium gallium arsenide) as the bottom layer.”
Germany’s Renewable Energy Industry (IWR) announced that over the weekend the country’s solar energy infrastructure met approximately 50% of the country’s energy demand. The IWR notes that more than 22 gigawatts of solar energy per hour was generated by the country’s various alternative energy systems and fed into the energy grid. This is comparable to the energy generated by 20 nuclear power plants operating at full capacity. This marks a new record for Germany and sets the bar higher for the global solar energy industry Government officials claim that this milestone is proof of the viability of solar energy. The fact that the country was able to meet half of its energy needs through the use of solar power during the weekend is being considered a major accomplishment. The German solar energy industry continues to break records and show that alternative energy should be taken more seriously by developed countries.
From a wind-power factory in this battleground state, President Obama urged Congress to extend tax credits he said would save jobs in the field of clean-energy production. Obama said continuing the production tax credit would save 37,000 jobs that would otherwise be at risk, an estimate his aides based on reports from industry officials. "If Congress doesn't act, companies like this one will take a hit. Jobs will be lost. That's not a guess. That's a fact," Obama said Thursday as he visited TPI Composites, a wind turbine blade manufacturer based in a town that's home to a closed Maytag factory. "We can't let that happen. We can't walk away from these jobs." The production tax credit, created in 1992 and extended nearly continuously since then, gives wind farms a credit of 2.2 cents per kilowatt-hour of energy produced. Industry advocates said it spurred $15.5 billion a year in private investment in the U.S. in the last five years. The credit is scheduled to expire at the end of the year.
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.
PV by nature is an intermittent energy source that can be affected greatly (even over the course of seconds) by weather influences such as passing clouds. While this variability may not be a concern for the individual PV system owner, it is for utilities or system operators that may have tens of thousands of grid-connected PV systems within their service territories.
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.
Hopefully both sides of the coin - cultural property protection in the face of any callous non-Indian energy development, and streamlined tribal energy development for sake of tribal self-determination - can be realized by the revised S. 1684. The protection of Indian Country, both in the long and short term, quite literally depends on it.
PPAs are best for organizations that own their own buildings or homes. Or plan to occupy their space for an extended period of time. Also, a property owner who has a large open property or rooftop space (such as a warehouse or distribution center) may also enter into a PPA in connection with a rooftop or property lease as a means to generate not only renewable energy, but also revenue from energy sales to the local utility.
The inability of some solar project developers to secure the right coverage coupled with concerns about the long-term viability of equipment manufacturers has created fear and uncertainty in the marketplace, preventing some investors from financing projects.
Tioga helped facilitate a first-of-its kind financing program ("the Morris Model") in which taxable bonds were issued to finance the solar program
