On the Interplay between Surface Roughness and Cell Thickness for Efficient CZTS Thin Film Solar Cells

G. M. Sharif Ullah AL-Mamun

Abstract


Today's thin-film photovoltaic technologies comprising CuInS2 (CIS), CuInGaSe2 (CIGS) and CdTe elements that are costly and rare and in the earth crust such as In, Ga, Te and toxic like Cd. Henceforth, in future, expense decrease, proficient and expanded creation, utilizing bounteously accessible nonharmful components, appear to be the fundamental issue to deliver large scale manufacturing and effective sunlight-based cells. Cu2ZnSnS4 (CZTS), having the kesterite structure, is perhaps the most encouraging absorber layer candidate for low-cost thin-film solar cells, as a result of its appropriate direct bandgap between 1.4 and 1.5 eV and enormous absorption coefficient, more than 104 cm-1. Additionally, it is made out of earth-plentiful and non-poisonous components, promising value decreases later on. "Recently, research in this area has gained momentum due to the desirability of producing Ga, In and Cd-free absorber layers and the potential to obtain new insights. Subsequently, this study addresses out advancement and present accomplishment of CZTS thin film solar cells, with the expectation of recognizing new ways for beneficial examination and mass mechanical creation. The general effectiveness discovered is around 11%, which is extremely acceptable and most elevated for single-intersection CZTS thin-film solar cells.
