Title:
LIGHT SOURCE EVALUATION DEVICE AND SOLAR CELL EVALUATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/020542
Kind Code:
A1
Abstract:
With this light source evaluation device (10) and solar cell evaluation device (1) employing same, a dependency P(λ, Ib) for each wavelength λ of a short-circuit current Ib from white bias light of a solar cell to be measured (2) that is pre-measured at each of a plurality i of illumination levels is treated as a spectral sensitivity Pi(λ) for each illumination level, and a value for adjusting the quantity of light of an illumination light source (3) that illuminates the solar cell (2) is computed using a spectral sensitivity Ps(λ), which is derived with a computation using the spectral sensitivity Pi(λ), a pre-supplied reference sunlight spectral irradiance S(λ), and a pre-measured spectral irradiance L(λ) of the illumination light source (3). It is thus possible for the light source evaluation device (10) and the solar cell evaluation device (1) employing same, with said configuration, to accurately carry out adjustment of the quantity of light of the illumination light source (3) when evaluating the solar cell (2), the spectral sensitivity whereof changes with the quantity of light.
