METHOD OF TESTING SOLAR CELLS
First Claim
1. A method of measuring the efficiency with which a solar cell converts incident photons into charge carriers, comprising the following steps:
- (a) illuminating the solar cell with a broadband light source;
(b) illuminating the solar cell with the broadband light source of which the intensity of a selected range of wavelengths has been reduced;
(c) determining the change in the number of photons incident on the cell and the change in the number of charge carriers produced by the cell between steps (a) and (b); and
(d) using the changes determined in step (c) to calculate the said efficiency measure.
