A new solar cell is described that relies on a thin layer of clean CdS in which a high-field domain extracts holes from p-type emitters without having pn-junctions involved. This design is highly advantageous for increasing the efficiency of the solar cell significantly, by avoiding junction leakage and by increasing the open circuit voltage to its theoretical value approaching the band gap at T = 0 K.
