METHOD AND APPARATUS FOR TESTING PHOTOVOLTAIC DEVICES

摘要

Apparatus (10) for simulating spectrum of solar radiation and testing a photovoltaic device (17) using the simulated spectrum (15) of solar radiation. The apparatus (10) includes a light-source device configured to reproducing spectrum (15) of solar radiation, the light- source device comprising a radiation plate (13) divided into a plurality of cells, and each of the cells comprises a plurality of light-emitting diodes emitting at least two different wavelengths, and a substrate support (16) disposed opposite to the light-source device. In one example, the plurality of light-emitting diodes emit a wavelength that is selected from the group consisting of colors blue, green, yellow, red, a first and a second color in infrared having different wavelengths with respect to each other.
