This paper presents a numerical investigation of Cu (In1-xGax) Se2 solar cell by using Silvaco TCAD tools. The validation of the CIGS model is performed by matching the electrical characteristics of the experimental and simulation results. For high-efficiency cell, magnesium fluoride (MgF2) has been proposed for antireflection (AR) coating on the top of the cell stack to maximize the photocurrent from the incident light intensity. The surface recombination velocity of CdS/CIGS heterojunction interface (under drift-diffusion transport) and element composition Ga/(In+Ga) ratio effect on the optical properties and electrical performances of CIGS absorber are investigated. The effect of single-layer magnesium fluoride (MgF2) anti-reflective coating (ARC) thickness on the output parameters is presented through modeling under AM1.5 illumination condition, 300K.

Abstract
This paper presents a numerical investigation of Cu (In1-xGax) Se2 solar cell by using Silvaco TCAD tools. The validation of the CIGS model is performed by matching the electrical characteristics of the experimental and simulation results. For high-efficiency cell, magnesium fluoride (MgF2) has been proposed for antireflection (AR) coating on the top of the cell stack to maximize the photocurrent from the incident light intensity. The surface recombination velocity of CdS/CIGS heterojunction interface (under drift-diffusion transport) and element composition Ga/(In+Ga) ratio effect on the optical properties and electrical performances of CIGS absorber are investigated. The effect of single-layer magnesium fluoride (MgF2) anti-reflective coating (ARC) thickness on the output parameters is presented through modeling under AM1.5 illumination condition, 300K.Pubblicazioni consigliate
