چکیده انگلیسی
Short minority carrier lifetime and low open circuit voltage (Voc) are key issues limiting the current efficiency development for Cu2ZnSnS4 (CZTS) thin film solar cells. This work presents the use of Cd ion soaking and post-heat treatment to increase the lifetime and Voc of CZTS. The time-resolved photoluminescence (TRPL) results confirmed that Cd ion soaking and post heat treatment is effective in enhancing the minority lifetime, from â¼10 ns up to â¼28 ns. With analyses of the current density- voltage (J-V) curves and external quantum efficiency (EQE) data, Cd ion soaking and subsequent post heat treatment is found to greatly reduce the recombination and improve the junction quality, contributing to a â¼70â¯mV Voc enhancement and resulting in the increased device efficiency of 7.6%, from 5.9%.
