Optimisation of interdigitated back contacts solar cells by two-dimensional numerical simulation

Abstract: In this paper we present the results of the simulation of interdigitated back contacts solar cell on thin-film (∼50μm) silicon layer. The influence of several parameters (surface recombination rate, substrate thickness and type, diffusion length, device geometry, doping levels) on device characteristics are simulated using the accurate two-dimensional numerical simulator DESSIS that allows to optimise the cell design.
