SCAPS modelling of ZnO/CdS/CdTe/CuO photovoltaic heterosystem

Abstract

The authors have developed a simple, cheap and reproducible technology for obtaining thin-film heterostructures based on CdTe with a given surface morphology during vacuum deposition, which contributes to their low cost [1, 2]. The critical dimensions (thicknesses) of individual layers of the heterostructure were substantiated, a simulation was performed and a wide range of optical properties was investigated [3]. It is shown that for the deposited CdS / CdTe heterostructure on glass it is possible to obtain an efficiency of 15.8%.
 Given that thin films are relatively new systems, their study can offer much wider opportunities for technological improvement of photovoltaic energy converters. According to the analysis of modern literature data, the efficiency can be increased by performing deposition on ITO films and introducing nanoparticles of controlled sizes.

Performance simulation of solar cell based on AZO/CdTe heterostructure by SCAPS 1D software

“…Main characteristic photovoltaic (PV) parameters short-circuit current density ( J sc), open-circuit voltage V oc, fill factor (FF) and efficiency (PCE) under standard illumination (AM 1.5 G 1000 W/ , 300 K) were obtained and studied. Studies on the analysis of CdTe-based solar cells using SCAPS-1D as base simulation software have been previously published [ 12 , 13 ]. Given its widespread and accepted use, this computer simulation tool was employed in this research to numerically analyze AZO/CdTe thin film heterostructure performance.…”

Influence of metal atom substitution on the electronic and optical properties of solid-state Cd0.75X0.25Te (X= Cu, Ag and Au) solutions

“…CdTe semiconductor has proven to be a leading compound for manufacturing costeffective second-generation photovoltaic devices [1]. Cadmium telluride is having a direct band gap with an energy of ~1.45 eV and a high absorbance (above 10 5 cm -1 ) [2][3][4]. This makes it an excellent light-absorbing layer for solar cells.…”

Design of Al:ZnO/p-Si Heterojunction Solar Cell Using SCAPS Simulation Program

“…It is organized in the form of a number of panels and is successfully used for complex modeling the optical and photoelectric properties of solar cells, for instance, ZnO/CdS/CdTe/CuO, Si-CdS-ZnO, CdS/CdTe etc. [2][3][4]. Additionally, it realistically simulates the electrical characteristics of heterojunction solar cells [5].…”
