Concentrator PV Technology

BSRsolar's concentrator PV-technology COOLPHOTON^TM significantly increases the economics of photovoltaic (PV) systems through front-side cooling of concentrator PV cells (concentration factor of up to 20) via a liquid filter.

The function of the filter is twofold: (1) to absorb the infrared radiation, i.e., photons supplying heat and (2) to let the UV and visible radiation pass through to the PV cells below. The filter consists of a fluid absorbing, storing and carrying thermal energy for other use.
