The chalcogenide semiconductors (e.g., CuGaSe2, AgInTe2, etc.) have lower melting points relative to their band gaps than the binary compound semiconductors (e.g., CdTe) or, even more so, the elementary semiconductors (e.g., Si.)
This can...

Microcrystalline silicon–germanium (μc-Si1−xGex:H) alloy films have been grown by 100-MHz glow-discharge of a SiH4/GeH4/H2 gas mixture. Alloys over a full range of compositions were prepared to gain a comprehensive understanding of their...

Generally speaking, renewable energy is more expensive than traditional sources and it's not yet efficient enough to be a major contributer to our energy needs. See http://www.renewableenergy101.info for more info.
First Solar Drops 'Holy Grail' Technology That Sank Solyndra
(Adds Chinese competition in third-to-last paragraph.)
Dec. 15 (Bloomberg) -- First Solar Inc. is closing a research project aimed at developing the same solar-panel material that doomed Solyndra LLC after a global supply glut drove down prices.
First Solar plans to fire about 100 employees, including 60 at a Santa Clara, California, research center, the Tempe, Arizona-based company said in a filing. The job cuts are part of a reorganization plan to narrow its focus to large utility-scale power plants and away from smaller, rooftop installations. It also slashed its profit and sales forecast.
Solyndra declared bankruptcy Sept. 6 saying it couldn’t compete after prices for polysilicon, the raw material in traditional solar cells, fell 64 percent this year. Global panel production has “effectively tripled” in the last three years, led by China, and demand is slowing in Europe and other regions where subsidies have been cut, said First Solar’s Chairman and Interim Chief Executive Officer Michael Ahearn.

The Renewable Energy Future Fund will form part of the Governments expanded $5.1 billion Clean Energy Initiative and complement the existing support provided through the Governments expanded Renewable Energy Target of 20 per cent by 2020. This additional funding brings the Governments total investments in renewable and clean energy and energy efficiency to over $10 billion.
