High effective area amorphous silicon solar cell using excimer laser process

A laser patterning method for fabricating integrated-type amorphous silicon (a-Si) solar cell submodules has been investigated. An excimer laser was used to fabricate integrated-type solar cell submodules with a size of 535 cm/sup 2/. By the use of the excimer laser, higher throughput and a larger effective area were obtained than with a YAG laser. These submodules had an efficiency of 8.17% under AM 1.5, 100-mW/cm/sup 2/ and an effective area rate of 93.1%.<
