Description
Summary:Sun simulators are employed to test the performance of photovoltaic (PV) devices, according to the standard International Electrotechnical Commission (IEC) 61215. Economical and technical analysis show that PV manufacturers need to integrate Sun simulators in the production process and, in particular, at the end of the production chain in order to measure the I-V curve and to evaluate the peak power of PV devices. Sun simulators need specific lamps to simulate the solar spectrum and a specific filter to simulate atmosphere absorbance. Such a filter can cost over 6 per square centimeter. The aim of this work is to develop an alternative filter. In particular, both chemical analysis and spectrophotometric measurements are carried out to evaluate if the Air Mass (AM) 1.5 G filter can be replaced by a cheaper material. Preliminary simulations show how specific compounds coated on a glass surface can absorb the Sun spectrum, such as the AM 1.5 filter, but with lower costs.
