Ageing of photovoltaic cells under Concentrated Light

A novel Automated System for Cooling and Measurement under Concentrated Light (ASCMCL) and a new method to study the accelerated ageing of photovoltaic cells by using concentrated light are presented. The measurement system created is an autonomous one that can be used without surveillance. By using the new method proposed in this paper, the time of the ageing accelerated test is significantly reduced. The measurements performed at the Solar Technology Laboratory of Paul Scherrer Institute, Villigen, Switzerland confirm the utility of the proposed system and method.
