Abstract :
There has been little investigative study of the impact of city pollutants on module efficiency. In this study we have exposed two commercial Copper Indium Diselenide modules in the heart of the city and let them accumulate with dust for a period of time. Their performance is being measured regularly and thoroughly using an outdoor IV-curve measuring system (OMS) developed by the University of Hong Kong Centre of Renewable Energy (HKU CORE) under the guidance of Dr. Wilhelm Durisch from Paul Schere Institute, Switzerland. Changes in performances under different solar irradiation and temperature will be compared and the impact will be observed. The results will more accurately estimate the long-term decrease of annual energy yield of a BIPV system installed in densely populated urban environment due to pollution. It will provide a useful guideline to the frequency of cleaning schedules so that a balance between energy yield and cleaning cost can be achieved
