Cu2ZnSn(S,Se)4 Nanocrystals as Light Harvesting Layer for Thin Film Solar Cells
碩士 === 國立臺灣科技大學 === 化學工程系 === 102 === Recently, copper zinc tin sulfide (Cu2ZnSnS4, CZTS) has attracted great attention as a material of earth-abundant, non-toxicity, and with novel absorption coefficient (>10-4 cm-1) to become a promising solid-state photovoltaic device material. CZTS is suitabl...
