Due to the aforementioned outstanding characteristics, many researchers are constantly working to develop perovskite solar cells to introduce them as a common energy source. However, previous studies have focused on improving different cell structures' efficiency or stability. But the price of solar cells is a crucial point for mass production and commercialization. Most of the perovskite solar cells currently available are confined to research labs due to the high cost of materials used to fabricate those solar cells. This massive price drawback hinders the mass production and commercialization of perovskite solar cells. It has been found in the study that HTM and gold (Au) contact require a significant portion (33.9%) of the total device cost .
