BigRef - Large Area PV Reference Cell

The BigRef is designed as reference cell for measurement and adjustment of irradiance for sun simulators. The the very precise calibration allows an exact determination of sun simulator irradiance. The BigRef can also be used for the measurement of non-uniformity of light for sun simulators for PV modules. Specially the large area of the sensor element offers a large advantage to reference cell designed as WPVS reference cells, as non-uniformity effects are compensated by the BigRef. Development and Design has been in Cooperation with Solar Cell Calibration Laboratory CalTeC - Solar Cells of Institute for Solar Energy Research Hamelin (ISFH).
