To provide a solar cell evaluation apparatus capable of measuring the characteristic distribution of light/electric conversion efficiency per unit area at respective positions of a solar cell, partial failures, partial defects and the positions, etc.
The solar cell evaluation apparatus includes: an entire surface irradiation light source 2 for irradiating the entire surface of the solar cell 1; a partial illumination light source 3 for partially irradiating the solar cell; scanning drive mechanisms 7 and 8 for the partial illumination light source, for driving the partial illumination light source and scanning an irradiation position on the solar cell; partial illumination position measuring devices 9 and 10 for measuring the position of partial illumination on the solar cell; and a current measuring device 6 for measuring a current for each partial illumination position of irradiation on the solar cell and measuring the light/electric conversion efficiency of the solar cell.
