Transparent solar panels are 50 times more productive than regular photovoltaics
Luke Dormehl for DigitalTrends: As the term “regular windows” suggests, users don’t have to replace the existing windows in their home, but need only treat them with a special process developed by the company.
“We apply liquid coatings to glass and plastic surfaces at ambient pressure, and dry these coatings at low temperature to produce transparent films,” Conklin continued. “We repeat these processes, and then collectively these coatings — and thus the glass and plastic surfaces — generate electricity.”
Of these coatings, the most important is the so-called “Active Layer,” through which electricity is generated by the absorption of light, and the transparent conductors, which allow the electricity to be extracted. “[The] coatings are primarily organic, primarily from carbon, hydrogen, nitrogen, and oxygen,” Conklin said. “We are constantly refining each of the layers to improve on the power we’re able to extract from these coatings and enhance their manufacturability.” Cont'd...
Solar cell is more efficient, costs less than its counterparts
Massachusetts Institute of Technology via Science Daily: A team of researchers from MIT and the Masdar Institute of Science and Technology may have found a way around this seemingly intractable tradeoff between efficiency and cost. The team has developed a new solar cell that combines two different layers of sunlight-absorbing material to harvest a broader range of the sun's energy. The researchers call the device a "step cell," because the two layers are arranged in a stepwise fashion, with the lower layer jutting out beneath the upper layer, in order to expose both layers to incoming sunlight. Such layered, or "multijunction," solar cells are typically expensive to manufacture, but the researchers also used a novel, low-cost manufacturing process for their step cell.
The team's step-cell concept can reach theoretical efficiencies above 40 percent and estimated practical efficiencies of 35 percent, prompting the team's principal investigators -- Masdar Institute's Ammar Nayfeh, associate professor of electrical engineering and computer science, and MIT's Eugene Fitzgerald, the Merton C. Flemings-SMA Professor of Materials Science and Engineering -- to plan a startup company to commercialize the promising solar cell. Cont'd...

PVinsights: Global solar prices deepens as polysilicon collapse
Polysilicon prices start to collapse obviously this week, particularly the price in China with more than 4% drops. The scope of polysilicon price correction was not enough, in contrast to the downstream components in August, leaving the stockpiles continues to pile up over the period as the trading were less active. However, as entering into a quarterly financial end in September, the increasing inventory pressure compound by sluggish downstream demand and slashed wafer prices eventually compromise Chinese polysilicon suppliers on adjusting prices quotes down dramatically. On the other hand, polysilicon prices out of China also extend the slump this week, but the price corrections are less noticeable than in China since the price baseline is much lower than that in China. As the result, without seeing any sign of global demand recovery that could possibly alleviate serious global supply glut soon, polysilicon supplier are forced to provide more price discounts in order to lessen the stock levels .

Making waves: Shetland tidal power breakthrough is another world first for Scotland
Martin Hannan for The National: HOUSEHOLDERS on the Shetland Isles were not aware of it, but when they plugged in their kettles recently, they were sharing in a bit of history.
For the Shetland Tidal Array at Bluemull Sound, installed by Nova Innovation of Edinburgh, has become the world’s first tidal power array to be connected to a grid and deliver power on a commercial basis – to dozens of homes on the islands.
The achievement has been hailed by environmentalists and the renewable industry as a turning point in the development of marine power.
Nova had shown its technology could work with a single turbine which generated electricity in March. But the installation of second turbine that is also working to the grid proves that large tidal power arrays can and do work. Commercially viable tidal power is seen as something of a Holy Grail by the industry, since it is one of the few renewable energy sources that is entirely predictable – as one industry source once put it: “there will be tidal power available as long as the moon is in the sky”.

NOVA INNOVATION DEPLOYS WORLD'S FIRST FULLY OPERATIONAL OFFSHORE TIDAL ARRAY IN SCOTLAND
The second in a series of three 100 kW turbines was deployed alongside the first turbine in August 2016, making this the first offshore tidal array in the world to deliver electricity to the grid.
Nova's success heralds a new era for tidal energy as a long-term source of predictable renewable power (unlike other forms of renewable energy).
Indian Scientists Design Solar Tree to Save Space for Solar Power Generation
Anjana Pasricha for VOA News: Indian scientists have designed a “solar tree” that they hope will help overcome one of the key challenges the country faces in the generation of solar power.
With photovoltaic panels placed at different levels on branches made of steel, “solar trees” could dramatically reduce the amount of land needed to develop solar parks.
“It takes about four-square meters of space to produce energy which otherwise would have required 400 square meters of space. So almost 100 times the space is saved, which as you know is very valuable,” said Daljit Singh Bedi, chief scientist at the Council of Scientific and Industrial Research (CSIR) in New Delhi, whose laboratory in Kolkata developed the tree.
A scarce resource in India, acquisition of land to develop roads, factories and other infrastructure is a sensitive issue that has led to frequent and sometimes violent protests from displaced people. Cont'd...
San Bernardino County rejects a controversial solar power plant proposed for the Mojave Desert
Louis Sahagun for The LA Times: The San Bernardino County Board of Supervisors has rejected a controversial solar plant proposed for the Mojave Desert’s Soda Mountains, citing concerns that the project would destroy habitat and block ancient trails used by bighorn sheep for thousands of years.
In a 3-2 vote, the board on Tuesday declined to certify documents required under state law in order to issue county permits for the project on public land along Interstate 15 near the entrances to Joshua Tree National Park and Death Valley National Park, and less than a mile from the Mojave National Preserve.
“We endorse renewable energy, but this was the wrong project in the wrong location,” said Supervisor Robert A. Lovingood. Cont'd...
