Numerical Analysis of SnO2/Zn2SnO4/n-CdS/p-CdTe Solar Cell Using the SCAPS-1D Simulation Software

Abstract

This research includes the use of CdTe in the design of a solar cell. The SCAPS-1D computer program was used to simulate thin cell capacity of CdTe/CdS by numerical analysis with the addition of a buffer layer (Zn2SnO4) to enhance cell efficiency. The thickness of the window layer (n-CdS) was reduced to 25nm with the inclusion of an insulating layer of 50 nm thickness to prevent leakage towards the forward bias with respect to the lower charge carriers. As for the absorber layer thickness (p-CdTe), it varied between 0.5µm and 6µm. The preferable thickness in the absorbent layer was 1.5µm. Different operating temperatures (298K-388K) were used, while the highest conversion efficiency (η=18.43%) was obtained with the rest of the solar cell parameters (Voc=0.967 V, Jsc= 26.66 mA/cm2, FF=71.40%).

As previously discussed, we initially optimized SnO 2 (ETL), BaZrS 3 (absorber), and Cu 2 S (HTL) in our base device by varying the thickness, carrier concentration, and defect density.…”

“…However, these materials tend to be expensive and less stable. Interestingly, inorganic ETLs are a promising alternative due to their high stability, easy preparation process, cost-effectiveness, and excellent electronic properties. , Considering these advantages, we have carefully curated a list of 12 promising inorganic ETLs, including Bi 2 S 3 , , ZrS 2 , , SnS 2 , In 2 S 3 , ZnS, Zn 2 SnO 4 , BaSnO 3 , Al 2 O 3 , , WO 3 , TiO 2 , ZnO, and SnO 2 for our simulation. On the other hand, the choice of HTLs significantly affects the device’s performance, durability, and production cost.…”

Numerical Simulation of High Efficiency Environment Friendly CuBi2O4-Based Thin-Film Solar Cell Using SCAPS-1D

“…Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si) [6][7][8]. On the other hand, cadmium (Cd) has frequently been used as an absorber layer material [9][10][11][12]. But it is also unfit for the environment.…”
