METHOD AND INSTRUMENT TO CORRECT ERROR IN OPTICAL MEASUREMENT OF SOLAR CELLS

摘要

PURPOSE: A method and a device for correcting an optical property measurement error of a solar cell are provided to produce a correction factor of the solar cell by installing a detector for scan, which moves on the plane. CONSTITUTION: A relative space distribution function e(x,y) of a radiation illumination of an artificial light source(10) is measured using a detector(30) for a scan which moves on a plane(x,y) of the upper horizontal surface of the receiving surface of a solar cell(20). A relative space distribution function r(x,y) of the sensitivity of the solar cell is measured. A correction factor about the space non-uniformity is produced by measuring a representative coordinate (xi,yi) of ΔxΔy that is a unit section formed by uniformly separating the irradiation area of the artificial light source.
