III-V Multi-junction solar cells and concentrating photovoltaic (CPV

It has been proven that the only realistic path to practical ultra-high efficiency solar cells is the monolithic multi-junction approach, i.e., to stack pn-junctions made of different semiconductor materials on top of each other. Each sub pn-junction, i.e., sub solar cell, converts a specific part of the sun''s spectrum. In this way, the energy of the sunlight photons is converted
