摘要

For silicon thin-film solar cells, it is well known that one of the most important methods for preparing amorphous silicon doped with hydrogen having good stability against light-soaking degradation is by properly tuning the H2 dilution ratio in the intrinsic I-layer. However, it is difficult to improve the longevity of a Gen 5 silicon thin-film tandem module by manipulating the H 2 ratio within one I-layer alone because hydrogen treatment can easily compromise the front P-layer. To solve this problem, we propose the 'graded I-layer' method, which incorporates multiple I-layers with different hydrogen dilution ratios in place of the original single I-layer. By this method, a solar cell could provide higher initial power, and the degradation ratio of the module could be reduced by approximately 2%.
