Performance evaluation of metal oxide transport and absorber layers for all oxide heterostructure solar cells with ∼26% efficiency

Optimizing the Efficiency of Lead‐Free Cs2TiI6‐Based Double Halide Perovskite Solar Cells Using SCAPS‐1D

“…This decrease was associated with the formation of additional localized scattering/recombination centers that occur by these defects, which lowered the effective carrier diffusion length and the device efficiency. [ 39 ] The optimal acceptor doping value for our device is 10 13 cm −3 .…”

Low-Intensity Light Detection with a High Detectivity Using 2D-Sb2Se3 Nanoflakes on 1D-ZnO Nanorods as Heterojunction Photodetectors

“…Furthermore, combining zinc oxide (ZnO) with Sb 2 Se 3 was proposed to enhance the optoelectronic properties . ZnO, which is a nontoxic material, has high charge-carrier mobility (200–300 cm 2 ·V –1 ·s –1 ), low-temperature synthesis and stability, and several optoelectronic applications. − Therefore, it can be a better alternative to highly toxic CdS when replacing the buffer layer . Although ZnO has a larger bandgap compared to CdS, it has a proper band alignment with respect to Sb 2 Se 3 .…”

“…15−17 Therefore, it can be a better alternative to highly toxic CdS when replacing the buffer layer. 18 Although ZnO has a larger bandgap compared to CdS, it has a proper band alignment with respect to Sb 2 Se 3 . Therefore, it is one of the best options as the buffer layer for Sb 2 Se 3 in the formation of a photovoltaic device.…”

Non‐Toxic and Stable Double Perovskite Solar Cells Based on Cs2AgSbX6 Light Harvester: First Principle Calculations‐Aided Theoretical Estimation

“…Nevertheless, researchers employ various numerical techniques based on density functional theory (DFT) and software packages such as the 1D Solar Cell Capacitance Simulator (SCAPS-1D) to understand the electronic structure of light harvesters and solar cell performance, respectively. [23][24][25][26][27] This study initially scrutinizes the Cs 2 AgSbX 6 double perovskite light harvester based on the DFT calculations, through the Cambridge Serial Total Energy Package (CASTEP). The obtained fundamental understanding of the electronic structure and the physical characteristics of Cs 2 AgSbX 6 double perovskite was thoroughly examined and loaded as input to the SCAPS-1D with other aiding layers.…”
