Abstract
Disclosed is a bifacial thin film solar cell, particularly a bifacial CuInGaS, thin film solar cell, fabricated by a paste coating method. According to several embodiments, the bifacial thin film solar cell results in a higher conversion efficiency of bifacial illumination than the simple sum of the efficiencies of upper and lower side illumination only, unlike those previously reported. The bifacial thin film solar cell exhibits many other effects described in the specification.
Claims11
A thin film solar cell comprising (a) a transparent conducting substrate, (b) an absorber layer formed on the transparent conducting substrate, and (c) a buffer layer, a window layer, and an electrode formed on the absorber layer, wherein the absorber layer is produced by a solution processing method.
