Abstract
A simulated sunlight irradiation apparatus of the present invention (100a) includes: a light guide plate (5) having an irradiation surface and a counter surface opposite to the irradiation surface; and a light absorbing member (8) which is provided on at least one of an irradiation surface side and a counter surface side of the light guide plate (5) and absorbs light in a predetermined wavelength region.
Claims12
A simulated sunlight irradiation apparatus, comprising:
- a light source emitting light;
- a spectrum adjusting member adjusting a spectrum of the light emitted from the light source;
- a light guide plate which the light whose spectrum has been adjusted by the spectrum adjusting member enters and in which the light is guided, the light guide plate having an irradiation surface and a counter surface opposite to the irradiation surface;
- a light extracting member causing the light which has entered the light guide plate to be extracted through the irradiation surface toward an irradiation target;
- and
- a light absorbing member absorbing light in a predetermined wavelength region, the light absorbing member being provided on at least one of an irradiation surface side and a counter surface side of the light guide plate.
A simulated sunlight irradiation apparatus which irradiates a solar cell with simulated sunlight in order to measure an output characteristic of the solar cell, comprising:
- a light source emitting light;
- a spectrum adjusting member adjusting a spectrum of the light emitted from the light source;
- a light guide plate which the light whose spectrum has been adjusted by the spectrum adjusting member enters and in which the light is guided, the light guide plate having an irradiation surface and a counter surface opposite to the irradiation surface;
- a light extracting member causing the light which has entered the light guide plate to be extracted through the irradiation surface toward an irradiation target;
- and
- a light absorbing member capable of absorbing light that is in a predetermined wavelength region and contained in reflected light which is simulated sunlight reflected from the solar cell, the light absorbing member being provided on at least one of an irradiation surface side and a counter surface side of the light guide plate.
