Simulation and optimization of the nSiC layerâ€™s thickness in a nSiC/pSi photovoltaic cell
Keywords:SiC, heterostructure, solar cell
Simulations of the emitter layer in 3C-SiC heterostructure solar cells were performed by means of SCAPS to model the optimal thickness and predict the influence on cellâ€™sÂ behaviour. Then, the cells have been elaborated by chemical vapor deposition and characterized. The opto-electrical measurements showed an improvement of the absorption of photons in the short wavelengths thanks to the thin layer of the emitter, and the non-degradation in bulk of the base cell. On the front side, the using of Ti/Au contacts also leads to an improvement in the absorption of photons thanks to the low series resistance.
