Abstract :
The successful monolithic interconnection of four thin-film single-crystal GaAs cells, demonstrating one of the key advantages of thin-film cells made by the cleavage of lateral epitaxy for transfer (CLEFT) process, is reported. Monolithically series-interconnected 16 cm 2 thin-film four-cell strings exhibiting a Voc of 4.04 V and a total-area submodule efficiency of 21.0% under AM 1.5 global illumination at 26°C was successfully fabricated. An eight-cell string which had a Voc of 7.96 V, an AM 1.5 efficiency of 21.2%, and a total submodule area of 2 cm2 was produced. Details of the cell fabrication process and the cell performance are presented
