STUDY THE ROLE OF EFFECTIVE PARAMETERS IN ENHANCEMENT OF THE SILICON SOLAR CELL PERFORMANCE USING PC1D SIMULATION

Abstract

The increased spread of the solar cell in the market relies on an improvement of the performance of silicon solar cell which is through study the role of effective parameters and focus on it to improve performance. In this study, detailed modelling of the solar cell was carried out so as to identify key parameters impacting efficiency. The impact of various parameters such as base resistivity, emitter doping concentration, front and rear surface recombination, back surface field, minority carrier lifetime, surface reflection and series and shunt resistance were investigated using PC1D software simulation. We are found that the top doping for emitter, bulk and back surface field were between 1×1019 cm3 and 1×1020 cm-3 . Where, the efficiency can be impacted by 2.7 % through emitter concentration variation, 1.5 % through FSRV, 1% through BSRV, and 1 % through bulk resistivity. The largest variation was observed for the minority carrier lifetime; it was observed that low lifetimes (~ 10-20 μs) are sufficient for efficiency of ~ 18 %. As for the surface reflection is concerned each 10 % increase in absolute reflection results in approximately 2 % efficiency reduction. As the largest variation was observed for the series and shunt resistance; it was observed that low series resistance (~ 0.01) and high shunt resistance (~ 100) are sufficient for the efficiency of ~ 19 %. The results from this simulation found that key parameters to improve the solar cell performance lay by optimizing emitter concentration, reduce surface reflection, series resistance low as possible, and shunt resistance high as possible.
