Currently, the perovskite solar cells (PSCs) have materialized out as a next-gen source of energy in the area of photovoltaic technology. Considering their cheap cost and producing high power, the commercialization of PSCs devices has become crucial. However, addressing stability in these cells has now become a current issue before its commercialization on large scale. A proper choice over deposition of top electrodes on the perovskite layer plays very vital role for maintaining the stability of device over longer period of time. The rear electrode plays vital role in producing stable PSCs. This book chapter reports the study on the comparison of various rear electrodes (metal electrodes, transparent conductive oxides (TMO) based electrodes, conductive polymers, and carbon-based electrodes) on the basis of their cost, efficiency, and stability. This chapter concludes the benefits and limitations of using rear electrodes materials in PSCs for practical device application.
