The Interdependence of the Kinematic and Intrinsic Parameters of a HIT Cell: The Effect of Charge Carrier Mobility

Abstract

This paper discusses the dependence of the kinematic and intrinsic parameters of a silicon heterojunction solar cell, highlighting mobility phenomena. First, a three-dimensional schematic of a HIT (Heterojunctions with Intrinsic Thin layer) cell is established to highlight mobility phenomena at the texturized hydrogenated indium oxide ( ) contact layer and active layers where charge carriers move. Next, mathematical equations linking the interacting physical parameters are developed, and the numerical resolution of these mathematical equations has led to results. The discussion of these results is based on charge carrier transport, more specifically the photocurrent densities of free electrons and excitons, and their contribution in terms of the photovoltaic cell's energy production efficiency.
