Abstract:

Different from the traditional silicon solar cells, new type solar cells composed of various kinds of materials, with different spectral responsivity, compatibility, stability performance, etc. All these bring great challenges for their accurate measurement of photo-electric conversion efficiency or other critical performance indexes. Combining with the present situation in domestic and international scope, this paper expounded the research progress of new type solar cells' efficiency measurement during these years, and illustrated emphatically the efficiency measurement method, traceability and calibration of standard value, calculation of spectral mismatch factor (MMF) and analysis of other influencing factors. We hope to provide a reference for the accurate characterization of the photo-electric properties of various new types of solar cells.

Key words: photo-electric conversion efficiency, new type solar cell, metrology, spectral mismatch factor (MMF)
