ABSTRACT:
A crystal of a semiconductor material has an electrically conducting loom assembly embedded therein, whereby the crystal and loom assembly define a unit which converts light or other electromagnetic radiation into an electrical current for flow to an external electrical circuit. The loom assembly has a plurality of electrodes coated with another semiconductor material so that the semiconductor materials define a plurality of n-p junctions within the crystal. Radiation absorbed by the crystal will liberate electrons which will flow across the junctions and along electrical paths formed in the loom assembly to conductor means which can be connected to an external electrical circuit. The loom assembly comprises a plurality of very small loom units comprised of pairs of spaced electrodes, one of the electrodes of each loom unit having a coating of a semiconductor material in contact with the semiconductor material of the crystal. The loom assembly can be made by laser cut tooling and the crystal can be grown on the loom assembly. The crystal can be mounted in any suitable manner to receive solar energy, such as in optical alignment with a lens system or at the focus of a curved mirror.
