Optimal cell selection for series connection in Cassegrain PV module

Image Number 7 for United States Patent #7994417.

A solar PV panel has an array of primary mirrors that collects and reflects solar radiation toward an array of dichroic secondary elements. The dichroic secondary elements reflect near-visible solar radiation to an array of near-visible radiation sensitive solar cells and simultaneously transmit infrared radiation to an array of infrared sensitive solar cells. The array of near-visible radiation sensitive cells and the array of infrared sensitive cells are wired in series. The optical properties of the dichoic secondary element, near-visible radiation sensitive cell, and IR sensitive cell are chosen for simultaneous maximum power production from the panel.
