CIGS is a compound semiconductor, with direct bandgap varying continuously from about 1.0 eV (for copper indium selenide) to about 1.7 eV (for copper gallium selenide). It is best known as a high efficiency thin-film solar cell material. CIGS solar cells can be fabricated on flexible substrates to make flexible, lightweight solar panels. Some key advantages of CIGS over other types of solar cells are higher output ratio, shorter energy pay-back time, wider spectrum response, stronger absorption, no light-induced degradation, low level of photons required. Over the years, scientists and engineers have worked tirelessly improving the efficiency to as high as 20.3%.
