摘要：

Amorphous silicon p-i-n single-junction and "micromorph" (amorphous/microcrystalline) tandem solar cells have been deposited on "inhouse" LP-CVD zinc oxide front-TCO. ZnO shows superior light-trapping behavior compared to SnO2 (Asahi type U). Up-scaling to modules by laser scribing has been developed, both for amorphous single-junction and for micromorph tandem cells on LP-CVD ZnO. Within our laboratory-size reactor an amorphous mini-module (22 cm(2)) with an aperture efficiency of 8.4 % after 200 h of light-soaking could be fabricated. In case of micromorph tandem modules (24 cm(2)) a stabilized aperture area efficiency of 9.8 % (initial 11 %) has been achieved. Modified micromorph tandem cells with an intermediate reflector between the a-Si:H top and the pc-Si:H bottom cell show almost stable behavior with respect to light-soaking.
