"We report on Germanium on Glass solar cells realized by wafer bonding, layer splitting and. epitaxial regrowth. We provide a detailed description of the layer transfer process and. discuss the material characterization. The solar cells are fabricated and tested to extract the. most significant figures of merit, evaluating their performance versus device area and. operating temperature. The cells exhibit typical conversion efficiencies exceeding 2.4%. under AM1. 5 irradiation and a maximum efficiency of 3.7% under concentrated excitation.
