We have achieved an open circuit voltage of 723mV and a fill factor of about 84% at 0.5μm layer thickness of n type material. Furthermore, the fill factor (FF) and power conversion efficiency (PCE) calculation helps to optimize the layer thickness. Fig.8 plots the calculated efficiency versus Sb for four. Moreover, the reflectance in the visible regime of solar spectrum can be reduced by increasing the p type layer thickness but this improvement is not believed to be significant and hence, the study suggests the n type as a better material for front side selection in comparisons to p type. Back surface recombination velocity is varied from 102 to 106 cm/s while Sf is constant at 105. The analysis indicated that the surface recombination in the short wavelength region on the front surface can be overcome by decreasing the n type front layer thickness and hence, improve the efficiency of cell.
characteristics I-V, external quantum efficiency (EQE) and open circuit voltage (Voc) helps to analyze the efficiency of solar cells. Figure 13 illustrates efficiency against energy band-gap of a solar cell, using the AM1.5G spectrum and the blackbody spectrum at T s 6000° K for one sun and full concentration (CC Max), the only recombination mechanism is radiative and 100 external fluorescence efficiency, which means that all emitted photons from the cell (issue from. The maximum power output from the solar cell is obtained by choosing the voltage V so that the product current-voltage ( IV) is a maximum. The p-n junction solar cell is investigated by PC1D simulation by keeping both p type and n type as a front/emitter side towards the irradiated solar spectrum. Solar cell efficiency is calculated by dividing a cell's electrical power output at its maximum power point by the input solar radiation and the surface area of the solar cell. Cumulative photo-generation and recombination along the distance from the front surface were simulated by PC1D V5.9. *Corresponding Author Email: published on 24 May, 2018.
