“…With increasing carrier concentration, the saturation current drops, resulting in a rise in V OC as well as the fill factor FF. This is because the highest shunt resistance and lowest series resistance result in a rise in V OC and FF (Noman et al, 2016). Finally, the current results reveal that the absorber layer's carrier density is 10 16 cm -3 , whereby the cell has the maximum efficiency.…”

In this work, thin-film solar cells based on Cadmium Selenide (CdSe) film were used, due to the low manufacturing cost and superior electronic properties, and this type of cell also achieves appropriate efficiency. The current work will focus on investigating the effect of the thickness and carrier concentration of the active layers in the cell, and the thickness of the window on the performance of the proposed solar cell, using the one-dimension solar cells capacitance simulation SCAPS-1D computer program. The proposed structure of this cell consists of ITO/n-CdSe/p-CdSe/Pt, where ITO was used as a window layer, n-CdSe as a buffer layer, p-CdSe as an absorber layer, and platinum Pt as a back conductive electrode. The results revealed that the cell performed best at thicknesses of 5000 and 100nm for the absorber and buffer layers, respectively, and with carrier concentrations of 10 16 and 10 17 cm -3 for the same layers. The optimal window layer thickness is 100nm. These variables yield open circuit voltage (V OC ), short circuit current density (J SC ), fill factor (FF) of 1.0845 V, 20.87 mA/cm 2 , 88.02% respectively, while the conversion efficiency of cell (Eff.) was obtained, which is 19.92%.

“…The working temperature of a solar cell plays a vital role in determining its performance and stability. This temperature of a CdTe solar cell structure can range from 283 K to 373 K under a sunlight of AM 1.5 G and CdTe possesses a comparatively low temperature coefficient which can protect the cell's performance at high temperature [19]. But still, there 3).…”

“…But still, there 3). The temperature is varied from 300 K to 360 K. Actually, the energy bandgap of materials decreases with the increase of temperature due to increased interatomic spacing along with reduced barrier potential seen by the electrons [19]. This decrease in bandgap results in a decrease in V oc [20].…”

“…The temperature dependence of FF shows that the FF increases at first up to 310 K for As doping due to decreasing resistance effects or increasing 'mobility-lifetime' products within the collection region [21] (figure 7(c)). Ag-doped CdTe, Cu-doped CdTe and As-doped CdTe (after 310 K) show a decrease in FF with the increasing temperature because of enhanced carrier collisions and recombinations [14,19,21].…”

“…Lastly, figure 7(d) shows the effect of temperature increase on the efficiency of the solar cell which is seen to be in a declining trend for all three dopants. This is because of the reduction in bandgap associated with increased temperature [19]. These efficiencies may be further lessened for several reasons such as resistive and reflective losses [20].…”

Cadmium telluride (CdTe)-based solar cells have been proving their potential for high efficiency performance for several decades. However, efficient p-type doping of CdTe has remained a critical challenge for decades thus limiting the performance of this type of solar cell. Thus, this work intends to assess the effects of various dopants and their optimization in order to obtain efficient photovoltaic (PV) performances. In the process we used numerical simulation software SCAPS-1D as it expedites and facilitates the modeling of a solar cell through optimizations and variations. The studied CdTe solar cell structure comprises multi-junction semiconductor layers such as n-ITO/n-ZnO/n-CdS/p-CdTe in a superstrate structure. Three different types of absorber layer dopants such as copper (Cu), silver (Ag) and arsenic (As) are used, respectively. The work started with the optimization of carrier concentration followed by the variation of the thickness of the absorber layer. The PV performances in terms of open-circuit voltage, short-circuit current density, fill factor and efficiency are presented and, after comparison, the As dopant is shown to be a promising candidate. Also, the working temperature is varied to obtain a suitable environment under which the solar cell can work efficiently.
