Abstract
We investigated the thermal stability of multilayered transparent electrodes composed of ZnO:Ga (GZO)/Ag/GZO layers for the application of large-scale perovskite solar cell (PSC) modules, which require a post-annealing temperature of 450â¯Â°C. The sheet resistance and transmittance of the GZO/Ag/GZO (50â¯nm/12â¯nm/50â¯nm) electrodes were encouragingly improved by an annealing test with a temperature variation from 25° to 450°C. The optimum value of the sheet resistance was 4.48â¯Î©/square at an annealing temperature of 450â¯Â°C. By a simulation of PSC module performance, we confirmed that PSC modules with our GZO/Ag/GZO multilayered transparent electrodes (4-5â¯Î©/square) suffer less performance degradation compared to those with conventional FTO transparent electrodes (8-15â¯Î©/square).
