Simulation And Optimization Of Solar Cell Based On Thin Film
Résumé: Abstract Thin film cadmium telluride (CdTe) is the the material for realization of low cost and high efficiency solar cell. The simulation has been performed under the consideration of incident solar radiation of 1kW/m2 and Air mass of 1.5 and stannic oxide (SnO2) and silver (Ag) has been considered as the anode and cathode of the CdTe/CDS solar cell respectively. Here, the voltage, current circuit, Fill Factor (FF) and Quantum Efficiency (QE) of the solar cell has been determined and analyzed, we find layer thickness of 4µn CdTe, 0.005 µm CDS, electron affinity of 3.5 ev, acceptor concentration of 3 × 1014cm-3. In this work, a conventional structure of CdTe thin film solar cells was investigated and conversion efficiency as high as 16.53% was achieved when thickness of CdS layer is 0.005 µm with the CdTe baseline structure of SnO2/CdS/CdTe. To explore the possibility of thin film and high efficiency CdTe/CDS solar cells. Moreover, it was found that there were scopes to increase cell efficiency by reducing the cadmium sulfide (CdS) window layer thickness. All the simulations have been done under SCAPS simulator
