Accurate Measurement of New Type Non-silicon Solar Cells' Photoelectric Conversion Efficiency

Abstract

Different from traditional silicon solar cells, new type non-silicon solar cells are composed of various kinds of materials, such as organic, perovskite, quantum dots and so on. They always show special performance in spectral responsivity, compatibility and stability, which brought great challenges for the accurate measurement of photoelectric conversion efficiency. We will illustrate a method for accurate efficiency measurement mainly in the view of metrology. Based on effective traceability and calibration of the standard value, a procedure for new type non-silicon solar cells' efficiency measurement would be proposed. Main influencing factors such as spectral mismatch will also be analysed. Hope to provide a reference method for the accurate characterization of the photo-electric properties of various new types of solar cells.
