  • Abstract
    A solar cell structure consisting of an n+p junction cell with a floating pn+ junction at the back side is proposed. It is proved that the back surface recombination velocity and the dark current in such a structure are greatly reduced in silicon cells with high-quality bulk material and good emitter surface passivation. Open-circuit voltage in the vicinity of 700 mV and efficiencies around 25% under one-sun illumination conditions are calculated for this structure
