Mfactor: A PC-based program for general spectral mismatch corrections

摘要

Reference cells are frequently used to determine incident light intensity during solar cell performance measurements. A problem arises when comparisons are made between cells tested under different spectral irradiances (spectra). This paper describes an IBM-PC compatible computer program, called Mfactor, developed in the Photovoltaic Device Measurement Laboratory (PDML) at Sandia that uses a generalized procedure for making spectral mismatch corrections. The program operation is described, and several examples are given. A new method to calibrate primary reference cells using a National Institute of Standards and Technology (NIST) lamp in conjunction with Mfactor is also presented. 4 refs., 4 figs., 6 tabs.
