Semiconductor substrate for a photovoltaic power module

摘要

A semiconductor substrate and a photovoltaic power module incorporating the semiconductor substrate. The substrate includes one or more bypass diodes formed integrally in the semiconductor substrate, each bypass diode corresponding to a respective one or more photovoltaic cells, and metallised zones being electrically and thermally coupled to the bypass diodes. The substrate enables photovoltaic cells to be placed close together, and has low thermal resistance. Methods of manufacturing the substrate and module are provided.
