I have no doubt that this successful cooperation with our French and German partners will drive further increase of CPV technology efficiency and competitiveness.”, About Soitec Soitec is an international manufacturing company, a world leader in generating and manufacturing revolutionary semiconductor materials at the frontier of the most exciting energy and electronic challenges. The multi-junction solar cell converts 46% of the solar light into electrical energy and was developed by Soitec and CEA-Leti, France, together with the Fraunhofer Institute for Solar Energy Systems ISE, Germany. Polycrystalline solar panels are also referred to as “multi-crystalline,” or many-crystal silicon. Achieved … As a result, efficiency is greatly improved, even more than what a monocrystalline solar cell will deliver. By stacking these layers on top of one other, a broader range of the light spectra is absorbed, improving the cell's overall efficiency. Leti is based in Grenoble, France, and has offices in Silicon Valley, Calif., and Tokyo. Spectrolab manufactures and tests fully-integrated solar panels for commercial, civil and defense missions. Tibbits, P. Beutel, M. Grave, C. Karcher, E. Oliva, G. Siefer, A. Wekkeli, M. Schachtner, F. Dimroth, A.W. Scientific publications about this topic: Fraunhofer ISEHeidenhofstr. This limiting … We are extremely pleased to hear that our result of 46% efficiency has now been independently confirmed by AIST in Japan”, explains Dr. Frank Dimroth, project manager for the cell development at the German Fraunhofer Institute for Solar Energy Systems ISE. Unfortunately, multi-junction solar cells are very expensive, so they are mainly used in high performance applications such as satellites at present.

Comparison of direct growth and wafer bonding for the fabrication of GaInP/GaAs dual-junction solar cells on silicon. With ever new technological developments, research and industry are nearing the theoretical efficiency limit for semiconductor silicon. IV characteristics of the new 4-junction solar cell with an efficiency of 46% at 50.8 W/cm2 which corresponds to a concentration ration of 508 times the solar AM1.5d (ASTM E927-10) spectrum. “CPV is the most efficient solar technology today and suitable for all countries with high direct normal irradiance.”, Jocelyne Wasselin, Vice President Solar Cell Product Development for Soitec, a company headquartered in France and a world leader in high performance semiconductor materials, says: “We are very proud of this new world record. The Institute is a member of the Fraunhofer-Gesellschaft, Europe’s largest application-oriented research organization. Because there are many crystals in each cell, there is less freedom for the electrons to move. 0.21 MB ], Photo: New record solar cell on a 100 mm wafer yielding approximately 500 concentrator solar cell devices [ JPG  Multi-Junction Solar Cells are the future of PV solar electricity generation. External Quantum Efficiency of the new fully integrated triple-junction solar cell with subcells in GaInP, AlGaAs and Silicon. A few months ago, Fraunhofer ISE reached a record efficiency for a triple-junction solar cell made of III-V and silicon material. Fraunhofer ISEHeidenhofstr. Silicon solar cells dominate the global photovoltaic market today with a share of 90 percent. If you know much about solar panels, then you will know that the general amount of energy that it is capable of using is about 20% of what it absorbs.
