Design and performance evaluation of all-inorganic AgTaS perovskite solar cells

Narrow bandgap AgTaS 3 perovskite can offer highly efficient thin film solar cells (SCs) and become Si counterparts that are leading in the market. Herein, we study the response of a n-CdS/p-AgTaS 3 /p + -Al 0.8 Ga 0.2 Sb device according to the variation of thickness, doping concentration, and defe...

Description
Summary:Narrow bandgap AgTaS 3 perovskite can offer highly efficient thin film solar cells (SCs) and become Si counterparts that are leading in the market. Herein, we study the response of a n-CdS/p-AgTaS 3 /p + -Al 0.8 Ga 0.2 Sb device according to the variation of thickness, doping concentration, and defect densities in each layer using a solar cell capacitance simulator (SCAPS-1D). The optimized cell shows a V OC of 0.78 V, PCE of 27.89% accompanied by a J SC of 46.37 mA cm −2 , and a fill factor of 77.06%, paving the way for novel double heterojunction perovskite photovoltaic (PV) cells with remarkable performance. Narrow bandgap AgTaS 3 perovskite can offer highly efficient thin film solar cells (SCs) and become Si counterparts that are leading in the market.
