Abstract
Different kinds of Dielectric/Metal/Dielectric (DMD) films have been broadly adopted as transparent electrodes of solar cells. It is crucial to simultaneously predict the D, M material and thickness which is hard accessed either by experiments or manually simulations. In this study, we employed a co-simulation approach involving transfer matrix method (TMM) and a genetic algorithm (GA) to solve this problem. It is revealed that DMD films of WO3/Ag/WO3 and AZO/Ag/AZO provide an averaged transmittance as high as ∼90% in 300–800 nm, which are expected to providing excellent front transparent electrodes for perovskite solar cells (PSCs). On this basis, 46.6% (11.8%) and 45.4% (11.3%) increment upon photocurrent and power conversion efficiency were observed compared with that of Ag (ITO) based PSC counterparts. The presented work is highly insightful for the design and application of DMD transparent electrodes, which facilitates the material and thickness of DMD films selection for future transparent electrodes of PSC.
