GaAs thin film solar cell introduction

Abstract:

This talk is about a thin-film single-junction GaAs solar cell fabrication using ELO process which with an independently confirmed solar energy conversion efficiency of 29.2%, under the global AM1.5 spectrum at one sun intensity. This new record for terrestrial modules under non-concentrated sunlight. Reduced shading, intrinsic electrical interconnect, optimized optical coupling, and high efficiency solar cells all contributed to the unmatched performance of this module. Behind these attributes lies the thin and flexible nature of solar material, which enables high conversion efficiency at the cell and module levels. Because of its thin-film characteristics, this module technology has the potential to reduce the cost of solar energy generation beyond grid parity. The unique combination of a flexible form factor and high performance in outdoor environments makes this technology extremely competitive for both traditional solar installations as well as a variety of advanced photovoltaic (PV) applications.
