A comprehensive model of four layered MINP + (metal-tunnel insulator - NP + semiconductor) structure incorporating an inhomogeneous impurity doping profile is numerically simulated. The influence of built-in electric field in the device on its performance is investigated. The drift fields are the result of the nonuniformaly doped semiconductor. The dependence of the minority carrier...
Fabrication of solar cells with very high efficiencies currently requires extremely complex processing. In order to make photovoltaics an economical large scale source of energy, very high efficiencies have to be achieved by low-cost processing. The innovative approach for the cost-effective production of highly efficient silicon solar cells presented in this paper is characterised by only four...
