TEST OF THE EUROPEAN JRC PERFORMANCE MODEL FOR c-Si PV MODULES

摘要

The relative efficiency with respect to Standard Testing Conditions (STC) of ten c-Si PV modules isstudied at various illumination levels and operating temperatures. A model proposed recently by a team led by theEuropean Joint Research Centre (JRC) is tested for generic mono- and mc-Si devices with screen-printed cells as wellas for three high-efficiency cell designs. Two of the modules are aged. Individual as well as averaged modelcoefficients are compared to values found in the literature. Theoretical relationships are proposed between the firsttwo model coefficients and I-V curve parameters such as ideality factor and series resistance. The fitted and predictedvalues agree reasonably well for the tested devices. The different performance of similar module types at intermediateand low irradiances is thus explained with solar cell physics. The derived equations may be useful to PVmanufacturers as quantitative guidelines for designing products with superior energy yields.
