Electrical and Optical Characterization at the PV Laboratory

Indoor electrical characterization of BIPV modules

The Photovoltaic Laboratory of CIEMAT includes AAA+ solar simulators, I-V curve tracers, bipolar power sources, etc., to conduct the electrical characterization of BIPV modules under controlled testing conditions. Electroluminescence equipment, thermal imaging cameras, and microscopes allow detecting and analyzing potential defects.

Optical characterization of BIPV modules

For the optical characterization of BIPV modules, the spectral reflectance and transmittance can be measured with a double-beam UV/Vis/NIR spectrophotometer equiped with an integrating sphere; daylighting, color rendering, and other optical properties, as well as the solar heat gain coefficient (SHGC), can then result from those measurements, according to the applicable standards (EN 410, ISO 950).
