Company called Solyndra has invented circular photovoltaic panels. They are seems to be more efficient than traditional solar PV panels and they are easier and cheeper to install too.
We know that usually CIGS are not as efficient as photovoltaic systems based on silicon cells. But they are more and more popular, quite a few companies [...]

After Nanosolar’s investment of $300 milion this week it is SoloPower which is raising almost $200 million to speed up manufacturing of its thin-film solar cells.
SoloPower is based in San Jose, California. The company makes solar cells from CIGS, which is a combination of copper, indium, gallium, and selenide which a number of solar companies [...]

Nanosolar to Accelerate Production

One of the companies at the forefront of the fight to make thin-film solar viable is Nanosolar, and they just announced some good news on their blog. They were always well capitalized, but they raised $300 million more to accelerate the expansion of their production capability, bringing their total funding to about [...]

The average efficiency of regular solar panels is 15 percent; thin-film solar cells register a lower efficiency percentage than that. Japan’s National Institute of Advanced Industrial Science and Technology (AIST), however, claims 17.7 percent efficiency for its flexible thin-film CIGS solar cell. To be able to achieve that impressive percentage, AIST devised CIGS technology called [...]

IBM becomed a partner with company Tokyo Ohka Kogyo (TOK). IBM wants to develop cheaper and more efficient solar power technologies based on CIGS ( copper-indium-gallium-selenide ). Those cells should be more than 15% efficient. This is much more efficient than usual 6% to 12% efficiency that current (CIGS) solar cells have achieved.
Classic photovoltaic solar [...]

That’s cool. The project is headed by the Abu Dhabi Future Energy Company (ADFEC). Initiated in 2006, the project is estimated to cost US$22 billion and take some eight years to build, with the first phase scheduled to be complete and habitable in 2009. That’s pretty soon.
The city will cover 6 square kilometres (2.3 sq [...]

CIGS cells use extremely thin layers of semiconductor material applied to a low-cost backing such as glass, flexible metallic foils, high-temperature polymers or stainless steel sheets. Thin-film cells require less energy to make and can be fabricated by a variety of processes. Because of this, they provide a promising path for providing more affordable [...]
