To apply the absolute electroluminescence (EL) method, which evaluates the Voc of solar cells from quantitative EL analysis, as an inspection technique for VIPV, we report the results of outdoor EL measurements taken during continuous on-road tests of a Toyota HiAce EV conversion vehicle equipped with photovoltaic (PV) modules. We also present results obtained after removing the solar cells from the EV to measure photovoltaic characteristics and to perform EL measurements indoors under controlled temperature, and we discuss the changes observed over the test period.
