Abstract :
1D and 2D numerical simulations can be employed to perform optimizations of thin film solar cells and analysis of the physical mechanisms affecting the performances. In this work we discuss optical optimizations of a CZTSe solar cell predicted by a 1D model and a 2D model implementing grain boundaries as p-type phases with low band gap. The results of the simulations point out the significant impact that these GBs can have on the Voc loss and possible correlations with other experimental results obtained by K-AFM and C-AFM.
