Abstract :
Optimised thicknesses of the individual layers in any thin film a-Si:H solar cell can be obtained using optical analysis methods. By minimising the reflectance using an optimal antireflection coating layer and selecting a suitable rear contact material, a significant increase in the photon collection efficiency at long wavelengths can be achieved. The effect of the variation in thicknesses of different layers on the performance characteristics of a cell is discussed. The calculated results and analyses show that the present method can be used directly to design any thin film solar cell with an optimised structure for a desired possible high efficiency
