Solar cell module configuration and printed circuit board substrate for solar cell modules

Abstract

The present invention discloses a solar module, preferably for use within a solar energy concentrator system. The solar module comprises multiple solar cells that are divided into sets. The solar cells constituting a set form a parallel circuit, while the sets are connected together in series. The sets are arranged such that they each generate substantially the same amount of current despite solar cells potentially receiving an uneven diffusion of solar radiation. The voltage of each set can thus be added together without yielding any significant efficiency loss. In a further embodiment, electrical contacts and conductors with relatively high resistance on the solar cells are located on their back sides, coupled to conductors with relatively low resistance on a PC board substrate incorporated as a substrate to the solar module. This circuit reduces the overall resistance of the circuit, especially when integrated to a solar energy concentrator system.
