L’effet des couches de TCO et BSF sur les Paramètres Electriques de la Cellule Photovoltaïque Cu In1-x Gax Se.

Abstract

Currently, the use of renewable energies, in particular solar photovoltaics, is largely in the majority. As such, improving the performance of cells based on Cu (In, Ga) Se2 has become very important for photovoltaic research. The study conducted in this thes is mainly based on the study of increasing the efficiency of the solar cell using SCAPS software to perform the simulation. Our study is summarized in two parts the first is to use the TCO as anti-reflective layer where the structure of the solar cell is composed of TCO / CdS / CIGS and the second part we added SnS as BSF layer to the structure of the cell so it becomes TCO / CdS / CuIn1-xGaxSe / SnS. We challenged the characteristic I = f (V) which isthe main technique used to characterize a solar cell, we defined the photovoltaic parameters: the open circuit voltage, the short circuit current, the form factor, and the efficiency conversion.
