3S Industries and CEA Liten (Laboratory of Innovation for New Energy Technologies) — the French technological research organization — have signed a three-year agreement to collaborate on the development of PV modules based on silicon-based heterojunction solar cells and the tools needed to produce this type of module.
CEA Liten uses the National Institute of Solar Energy (INES) to conduct research on improving the performance of Si cells through the optimization of manufacturing processes and the introduction of new cell designs based on micro and nanotechnologies. The joint development program between 3S and CEA Liten is aimed at improving the speed of the development of innovative applications such as CEA’s 20% efficiency heterojunction solar cell.
The next step on from the 20% efficiency in this joint development program is to develop the inherent bifacial potential of the heterojunction cells, offering the possibility to harvest the solar energy from both sides of the cell. If this development process is successful, the resulting module efficiency could be increased by as much as 30%.
