Performance analysis of an efficient and stable perovskite solar cell and a comparative study of incorporating metal oxide transport layers

Abstract: As poor stability is the primary constraint for the commercialization of perovskite solar cells, improving stability has been the primary focus of recent research works regarding solar cells that make use of perovskite materials. Different metal oxide transport layers are being used with the aim of fabricating stable perovskite solar cells. A stable and efficient solar cell with both metal oxide transport layers (ZnO and N i O X … Show more

“…There was only experimental research in the early stage of this class of PV technology. However, many simulation works of PSCs have been published in recent years [ 10 , 11 , 12 ]. In most of these articles, the thickness of different layers, doping profile, defect concentration in materials and interfaces, and device resistances (series and shunt) are varied to optimize the device [ 13 , 14 ].…”

“…Aiming to improve the stability of PSCs, several techniques were implemented in the past, which include using different electron transport layers (ETLs) and HTLs, using buffer layers, modifying interface layer between two materials, encapsulation, and using hybrid materials for different layers. [ 36,43,44 ] While none of these brought the desired stability, these techniques improved the stability to some extent. The underlying physics of the degradation mechanisms needs to be studied more intuitively for bringing desired stability.…”

“…This enhancement in solar cell performance is caused by the fact that when doping charge density increases, the ETL material's internal electric field also increases, raising the charge transport velocity and, thus, the conductivity. [ 35 ] However, high doping leads to the creation of coulomb traps, reducing electron charge mobility. [ 24 ] In structure 1: we have optimized the N D of WS 2 as 10 18 cm −3 for the best PSC performance.…”
