Method of making photoelectric conversion device

A method of manufacturing a plurality of photoelectric conversion devices, said method comprising the steps of:

• forming a plurality of said photoelectric electric conversion devices on a substrate, each of said device comprising a plurality of interconnected photo-electric transducers, wherein each of said transducers comprises a first electrode, a photoelectric conversion semiconductor layer formed on said first electrode, and a second electrode formed on said semiconductor layer, wherein isolation grooves are formed through said second electrodes, respectively, along opposite sides thereof;
• and
• severing said substrate together with said photoelectric transducers in order to form said plurality of photoelectric conversion devices,
• wherein side edges of said semiconductor layer in each device are coextensive with side edges of at least one of said first and second electrodes.

A method of manufacturing a plurality of photovoltaic arrays comprising the steps of:

• forming a plurality of first spaced apart electrically conducting segments on a substrate;
• forming a photosensitive semiconductor layer over each segment;
• forming a plurality of second spaced apart electrically conducting segments on said semiconductor layer in order that a laminate structure comprising a plurality of photovoltaic cells is formed;
• and
• severing said laminate structure and said substrate into a plurality of photovoltaic arrays;
• wherein said substrate has at least one side edge surface which forms a common face with a side edge of said laminate structure.
