Researching CIGS thin-film solar cells

Sharc25, an acronym for ’super high efficiency Cu(In, Ga)Se2 thin-film solar cells approaching 25%,‘ aims to raise the bar even higher. The five research institutes, four universities and two companies are pursuing three strategies to achieve this goal: Improve the absorber material, harness the power of new designs for more efficient surfaces and interfaces, and optimize light management to raise the efficiency threshold another few notches. An increase of about three percentage points to 25 percent efficiency would be quite the leap in performance.
