Efficiency Improvement Study for GaAs Solar Cells. GaAs has the ability to deliver the highest energy conversion efficiencies, which is a measure of how much of the sun’s energy is converted to electricity. In fact, all of the world records for high-efficiency solar cells are held by some form of a GaAs solar cell [96,97,100]., 17.07.2019 · We introduce a novel germanium-on-nothing (GON) technology to fabricate ultrathin Ge films for lightweight and thin GaAs solar cells. GON membranes formed by reorganization of cylindrical pores during annealing enable the growth and transfer of GaAs cells and substrate reuse. Compared with previous porous Ge studies, we significantly improve the surface quality of reformed Ge by engineering.
