Abstract:
Over the past few years organic-inorganic halide perovskite solar cells have drawn an extensive attraction due to high solar cell efficiencies, which have gone past 20%. The issue that still prevails is the stability of these perovskite based solar cells. One of the obvious reasons is the fast degradation under high relative humidity due to water-solubility of the organic component of the material. So, aim of the research is to figure out and design a hydrophobic hole transport layer which will prevent the moisture to barge in, hence, saving the integrity of the organic component of the cell and as result improving the stability of the whole cell. PbPc and NiO are considered as the options to encounter the issue of moisture. PbPc has shown good hydrophobic abilities with a contact angle of 86.1°, apart from great hole mobility traits. While, NiO seems to have lower resistance to the moisture as contact angle was hard to calculate, though it can be a good hole transport candidate.
