Efficiency Improvement of Polycrystalline Silicon Solar Cells using a Grain boundary treatment
결정입계 처리에 따른 다결정 실리콘 태양전지의 효율 향상
Abstract
A solar cell conversion effiency was degraded by grain boundary effect in polycrystalline silicon. Grain boundaries acted as potential barriers as well as recombination centers for the photo-generated carriers. To reduce these effects of the grain boundaries we investigated various influencing factors such as emitter thickness thermal treatment preferential chemical etching of grain boundaries grid design contact metal and top metallization along boundaries.
