In this study we study a BSF layer structure of GaInp solar cell, windows layer, the effect of surface texturisation, surface recombines speed and we search for technological parameters of this leading to its optimized performance ( using PC1D simulator). The optimized structure gives the following results: 18.1% and FF = 84.80%. Keywords: GaInP;solar cell;BSF Layers and external quantum efficacies
