Thermally Deposited Sb2Se3/CdS-Based Solar Cell: Experimental and Theoretical Analysis

Abstract

As a promising solar absorber material, antimony selenide (Sb2Se3) has gained popularity. However, a lack of knowledge regarding material and device physics has slowed the rapid growth of Sb2Se3-based devices. This study compares the experimental and computational analysis of the photovoltaic performance of Sb2Se3-/CdS-based solar cells. We construct a specific device that may be produced in any lab using the thermal evaporation technique. Experimentally, efficiency is improved from 0.96% to 1.36% by varying the absorber’s thickness. Experimental information on Sb2Se3, such as the band gap and thickness, is used in the simulation to check the performance of the device after the optimization of various other parameters, including the series and shunt resistance, and a theoretical maximum efficiency of 4.42% is achieved. Further, the device’s efficiency is improved to 11.27% by optimizing the various parameters of the active layer. It thus is demonstrated that the band gap and thickness of active layers strongly affect the overall performance of a photovoltaic device.

“…To take advantage of acoustic waves of lower frequency in marine and industrial environments, Xiao et al [ 8 ] present a novel acoustic triboelectric nanogenerator comprising a quarter-wavelength resonant tube, an FEP membrane, an evenly perforated aluminum film, and a conductive coating of carbon nanotube. To efficiently manufacture Sb 2 Se 3 /CdS-based solar cells for solar energy harvesting, Kumari et al [ 9 ] developed a device designed for easy reproduction in any laboratory through the utilization of the thermal evaporation technique. Wong et al [ 10 ] utilized a BN/GaN layered composite along with aluminum to fabricate Schottky diodes with the goal of harvesting high-frequency wireless energy.…”
