Tokyo Ohka Kogyo Co., Ltd. (TOK) and IBM are teaming up to cut the cost of solar energy. Current solar cell systems rely largely on silicon for converting sunshine to energy and are less efficient and more expensive than other energy sources. IBM and TOK will focus on making CIGS (Copper-Indium-Gallium-Selenide) solar cell modules, an alternative to silicon.

Thin-film CIGS solar cells can be 100 times thinner than silicon-wafer cells. And because they can be deposited on cheap glass substrates, they cost less. They could also be arranged on a flexible backing, suitable for the tops and sides of buildings, tinted windows and other surfaces.
