This paper explores the development and
simulation of cadmium-free solar cells based on
Antimony tri-selenium (Sb2Se3) absorber materials, with
the integration of zinc sulfide (ZnS) buffer layers. The
aim is to replace cadmium-based materials with
environmentally friendly alternatives while maintaining
or improving the efficiency of thin-film solar cells. We
utilize the SCAPS-1D (Solar Cell Capacitance Simulator)
software to model and simulate the electrical and optical
characteristics of the proposed solar cell structure. This
work used SCAPS-1D software to construct and
quantitatively analyze solar cells made of high-efficiency
Antimony tri-selenium (Sb2Se3) and Zinc sulfide (ZnS).
This study examines how the thickness of the absorber
surface and the buffering layer affects the efficiency of
solar cells. Cadmium has been avoided because of its
significant toxicity to the environment, for making solar
cells which is suitable and efficient. Various photovoltaic
parameters have been determined using ZnS as a buffer
layer. By varying the depth of the absorber layer from
0.6μm to 0.5μm and the thickness of the buffer layer from
0.06 μm to 0.2 μm author tried to investigate the
properties of solar cell.
