Abstract
The Al/SiOx/p-Si MIS tunnel contact is an essential part of metal-insulator-semiconductor inversion-layer (MIS-IL) silicon solar cells. We experimentally determined the recombination properties (saturation current density J0 and ideality factor n) of the MIS contact in MIS-IL silicon solar cells fabricated at ISFH. Based on these measurements, it has been possible to resolve the contribution of the MIS contact to the total recombination losses in 1-sun illuminated MIS-IL solar cells by means of 2D numerical modeling. Furthermore, a 2D numerical optimization study is performed where the optimum width of the MIS contact fingers of advanced MIS-IL silicon solar cells is determined
