Development of instruments and testing equipment
Concentrator PV (CPV) technology has some features that distinguish it from conventional PV based on silicon cells. One is the use of optics systems to concentrate light in the cell, up to 1000 times the incoming solar radiation, which implies very narrow angular tolerances. Other is the use of very high efficiency solar cells, particularly multi-junction solar cells for the case of High Concentration PV (HCPV), with significantly higher spectral sensitivity. Both characteristics cause common procedures, instruments and equipment used in conventional PV are not applicable to CPV.
The ISI group of the IES has pioneered the development of procedures for CPV characterization and its implementation in instruments and testing equipment, both for the laboratory and the production line. Most of the results and know-how have been transferred to the industry, primarily to a UPM spin-off, Solar Added Value. The most important products resulting from these developments are:
