Perovskite solar cells consist of 3 main layers and other supporting layers. The three main layers are the hole transport material(HTM), absorber layer, and electron transport material(ETM). Although each layer is important, the impact of expense is more dependent on HTM. A study has found that HTM and back contact materials contribute 33.9% of the total cost of the device . Previous studies have shown that HTM has various significance from performance improvement to increasing stability. Wolfgang Tress et al. showed that the performance of perovskite solar cells increased by reducing recombination and increasing absorption due to HTM of the cell and Manon Spalla et al. have shown the impact of HTM on the stability of perovskite solar cells (PSC).
