摘要： A photovoltaic cell incorporating a semiconductor element (10) composed entirely of a single conductivity type. A biasing agent (26) having a work function different from that of the semiconductor element overlies a face of the element and produces a band bending and thus an electric field in a space charge region. Electrodes are in contact with the semiconductor element within the space charge region. Carriers generated by light absorbed in the semiconductor element are accelerated toward the electrodes by the field.

摘要： A photovoltaic cell includes a semiconductor element (20) formed from a direct semiconductor and a transparent biasing agent (28) overlying a first portion of the front face (22) of the semiconductor, the biasing agent producing a first depletion region (30) in the semiconductor element. A collector (40) directly contacts a second portion of the front face. The collector produces a second depletion region (44) in the semiconductor element. The collector (40) is out of direct conductive contact with the biasing agent (28) but in proximity to the biasing agent. A continuous region at least partially depleted of majority carriers extends between the first and second depletion regions at the front face of the semiconductor element, The continuous region may include overlapping portions of the first and second depletion regions (30,44), or may include an additional depletion region (160) formed by a charged dielectric (147).
