“…The model, as mentioned above, was expanded to the design of the future high-efficiency solar cell for VIPV application in the worst-case combination of atmospheric parameters [35] and realistic atmospheric parameters and measured spectrum [36]. The atmospheric parameters that impact performance of high-efficiency solar cells are identified using a statistical approach [37] and also to concentrator photovoltaic (CPV) [38] that is recently considered as a right candidate [39], fine-tuning of the bandgap design for VIPV application based-on the model as mentioned above [40], prediction of the energy yield with consideration of the spectrum and angular issues [41], and the rating method of the VIPV with consideration of above issues [42]. The detailed information of the high-efficiency PV modules used for the validation of the model is found in the article by Ota [43].…”

The energy yield of vehicle-integrated photovoltaics (VIPV) differs from that of standard photovoltaics (PV). It is mainly by the difference of the solar irradiance onto the car roof and car bodies as well as its curved shape. Both meaningful and practical modeling and measurement of solar irradiance for VIPV need to be established, rather than the extension of the current technologies. The solar irradiance is modeled by a random distribution of shading objects and car orientation with the correction of the curved surface of the PV modules. The measurement of the solar irradiance onto the car roof and car body is done using five pyranometers in five local axes on the car for one year. The measured dynamic solar irradiance onto the car body and car roof is used for validation of the solar irradiance model in the car.

“…The angular distribution model is crucial both to the validation of the 3-D solar irradiance model around the car-body and optimization design of the high-performance static concentrator module on the car-roof [28][29][30][31][32][33]. In case that the high-efficiency multi-junction cells are used for VIPV, it is essential to consider the spectrum impact, correctly, the cross effect between spectrum and angular distribution of the solar irradiance [34][35][36][37][38][39][40][41][42]. The angular distribution model is also useful for this purpose.…”
