Abstract
In this work, we study the influence of various technological factors on silicon solar cells efficiency. We use simulation by personal computer one dimension software package (PC1D) solving equations describing the transport of electrons and holes in devices based on semiconductor materials. We highlight the most critical steps and the technological factors to be improved to increase solar cells efficiency. We also discuss the influence of cell front face reflection, impurity concentration of the emitter and the base as well as the introduction of a p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> layer known as BSF, to reduce recombination losses in the cell rear face.
