“…The angular distribution model is crucial both to the validation of the 3D solar irradiance model around the car body and optimization design of the high-performance static concentrator module (CPV) on the car roof [2]. For example, a new type of static concentrators consists of an array of dielectric lenses [28], its optimization algorithm for VIPV [29], combination to high-efficiency on Si tandem solar cells enhanced by an innovative partial concentrator configuration [30], its prototype [31], and demonstration to VIPV application [32]. In case the high-efficiency multi-junction cells are used for VIPV, it is essential to consider the spectrum impact correctly of the cross effect between the spectrum and angular distribution of the solar irradiance [33].…”

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 of the solar irradiance was calculated by the weighted histogram of the angular distribution. 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].…”

“…To mimic this situation, the random model was made by three steps (see 4th to sixth rows of Table 1). Specifically, the number of the shaded cells in each string was allocated using Equation (19), and the short-circuit current from each cell impacted by shading was given in equation (2). Note both equation (1) and equation (2) contains Boolean algebra.…”
