ABSTRACT:
In order to provide an uncomplicated and economical front surface contact for photovoltaic cells (10) with good current discharge capability and high radiation permeability, the front surface contact (20) is composed of several layer (22, 24, 26) which are essentially unaligned with respect each other. The layers (22, 24, 26) are composed of different materials, which guarantes good ohmic coupling to the light incident semiconductor layer, good collection of free charge carriers in the semiconductor layer, and good discharge of same to a load device.
