Application: Method and device for optimising photovoltaic panels and photovoltaic panels optimised using this method (Patent ID: US20230421094A1)

The patent filed by Electricite de France SA describes a method for optimizing an existing generator system based on photovoltaic cells by adding additional modules with different types of cells to achieve an operating voltage equal to that of the existing panel. The method involves determining the operating voltage of the existing panel, producing additional modules with cells of a different band gap width, and positioning these modules to overlap the existing panel while being connected in parallel. The configuration and arrangement of the cells in the additional modules are calculated based on the dimensions of the existing panel to maximize power output.

Furthermore, the optimized panel resulting from this method includes the existing panel and additional modules connected in parallel with connection traces. The additional module can be fixed to the existing panel using various means such as transparent encapsulant material or mechanical fastening. The cells in the additional module can be of thin-film technology or other specific photovoltaic technologies like CIGS, Perovskite, CdTe, or amorphous silicon with different band gaps. The patent also covers different types of existing panels, such as full-cell, half-cell, or shingle-cell panels, and provides for an additional module specifically designed for implementing the optimized panel according to the described method.
