The effect of post-annealing on the performance of the Cu₂ZnSnS₄ solar cells.

ABSTRACT: Cu₂ZnSnS₄ (CZTS) solar cells commonly undergo post-annealing treatments to enhance their performance. However, multiple concurrent effects, including Cu-Zn disorder, Na diffusion from the back contact, CZTS grain boundary passivation, and elemental interdiffusion at the CdS/CZTS interface, can occur simultaneously during post-annealing, making it challenging to isolate their specific influence on device performance. To address this complexity, we have utilized Cu-Zn-disordered CZTS absorbers to eliminate the influence of Cu-Zn disorder in this study. Post-annealing experiments conducted at 120 to 300 °C in nitrogen and air atmospheres aim to decouple and assess the impact of different annealing conditions on the performance of CZTS solar cells. Our findings suggest th
