Band tails in CZTSSe have been commonly attributed as the cause of the low open circuit voltages observed in many CZTSSe solar cells. Various simplified models have been proposed in literature to account for these band tail effects. However, in order to create a physically accurate numerical model for CZTSSe, it is necessary to build a more sophisticated band tail model such as those commonly used...
Thin film solar cells with CIGSSe and CZTSSe absorber layers fabricated from nanocrystal inks represent economically scalable technologies for alternative sources of energy. Although these two materials share similar properties important to functioning as a photovoltaic absorber, lab scale CIGSSe devices have achieved power conversion efficiencies 1.5 to 2 times higher than their CZTSSe counterparts...
In this work we present the improved efficiency of nanocrystal ink based Cu2ZnSn(S, Se)4 (CZTSSe) solar cells to 9.15%. CZTSSe devices prepared from nanocrystal inks are known for the presence of an unintended amorphous/fine-grained layer (unsintered layer) near the back contact. We demonstrate the ability to reduce the proportion of the unsintered layer in the final film through improved nanocrystal...
