THE INFLUENCE OF THE CAPSULATION ON THE EFFICIENCY OF PV-MODULES

Performance of PV-modules is often in contradiction to a forecast made on the basis of bare cells. An overview on the factors influencing the efficiency, like optical and thermal characteristics, show that insufficient heat-transfer result in a low efficiency caused by high cell temperatures and increasing reflection losses due to a temperature dependency of material properties. In order to enhance performance some efficient cooling strategies should be taken into account.
