Lowering perimeter recombination losses in micro-concentrator solar cells: A simulation study

A device simulation study regarding perimeter recombination losses in micro-concentrator solar cells is presented. Perimeter losses for traditional and heterojunction designs were computed under dark and illuminated conditions for different solar cell sizes and surface state densities. A 2D device simulation model based on SRH recombination has shown that the use of heterojunction designs could help mitigate perimeter recombination for micro- CPV solar cells
