Sl.No. Synosis Points
1 This part of IS 12762 describes the procedure for correcting the spectral mismatch error introduced in the testing of a photovoltaic device, caused by the mismatch between the test spectrum and the reference spectrum (e.g. AM1.5 spectrum) and by the mismatch between the spectral responsivities (SR) of the reference device and of the device under test and therewith reduce the systematic uncertainty.
2 This procedure is valid for single-junction devices but the principle may be extended to cover multi-junction devices.
