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 .
