Abstract

— Throughout this study, SCAPS-1D 3.3 software is adopted for the analysis and
designing of energy - efficient CdTe / CdS-based solar cells. This article highlights the
influence of operating thermal performance of solar cells based on the CdTe. The parameters
for photovoltaics were determined in various absorber layers, buffer layers, window layer
thicknesses (CdTe, CdS and SnO2). We simulated the J-V characteristics, starting with a
good base structure. Analysis of the absorber and window influence, buffer layer thicknesses,
on the basic characteristics of open circuit voltage, fill factor, short circuit current, and the
efficiency of solar energy conversion were conducted. Great attention has been paid to the
variation in operating temperature to investigate the dependency on, temperature. The results
of the simulation offered an optimized value for the thickness of the absorber and buffer
layers. An increase in temperature also had a powerful effect on the CeTe / CdS solar cells.
Under the AM1.5 G spectrum and one sun, the optimized solar cell has recorded an
efficiency of > 14 %. The parameters that gave the optimum conversion efficiency were:
CdTe 3000nm, CdS 50nm, SnO2 500nm, and(at) T 300k. The I -V characteristics were Voc=
0.8317 volts, Jsc= 23.15 mA/cm2, FF% = 77.48, and ?%=14.73.Table 1 and Figure. 18
summarise the best performance for the current solar cell. The results of this simulation help
to provide some significant guidance for further work in designing multi-junction solar cells.
