Solar Simulator Uniformity Mapper

This uniformity tester uses an array of solar cells to assess the uniformity of light on its surface. The 8 x 8 array of solar cells covers a 21 x 21 cm plane, enabling the system to test solar simulators with a 21 x 21 cm illumination area. A 6 x 6 subset of these cells can be used to assess the uniformity of light from simulators with a 15.6 x 15.6 cm illumination area.

The tester enables solar simulator users and manufacturers to quickly optimize or certify light beam uniformity. Light from the solar simulator causes current to flow in the solar cells. The signal conditioning circuitry provides signals proportional to this current to the data acquisition equipment, which provides data to the computer. The computer interprets the data, provides a graphical display of the uniformity, maintains calibration information and saves test data.
