Abstract :
We introduce a one-side metallization scheme for monocrystalline Si thin-film modules from layer transfer. The mini-modules have an area of 5/spl times/5 cm/sup 2/ and consist of five series-connected cells with a thickness of 18 /spl mu/m. We achieve a short-circuit current of 145 mA (29 mA/cm/sup 2/ per cell) and an open-circuit voltage of 3098 mV (619.3 mV per cell) under AM1.5g-illumination at 1000 W/m/sup 2/. The efficiency is 9.1% due to a poor fill factor. A reference module with a two-side metallization reaches a total area efficiency of 12.3%.
