Solar cell quantum efficiency test method1 ScopeThis standard specifies the conditions, principles, tests and data processing methods for solar cell quantum efficiency testing. This standard applies to the single-junction, multi-junction solar cell quantum efficiency test.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 2297-1989 Solar photovoltaic energy system terminology3 Terms and definitionsThe terms and definitions defined in GB/T 2297-1989 apply to this document.4 Test purposesThe solar cell quantum efficiency obtained by the method given in this standard can be used to characterize the photo-generated carrier capacity and device structure of solar cell devices.5 Sample preparation and test conditionsSample preparation and test conditions are as follows. a) The device under test shall be stable and shall not undergo performance changes due to illumination; b) environmental pressure. atmospheric pressure; c) Sample test temperature. 25 ° C ± 2 ° C.6 Test principleIrradiating a solar cell with monochromatic light of different wavelengths, when the photon energy is greater than the corresponding band gap width of the solar cell material, the electricity is excited Sub-hole pairs; when a circuit is formed externally, the photo-generated carriers form a current. Solar cell quantum efficiency is defined as a certain wave Long incident photons produce the number of electron-hole pairs in the outer circuit. Then the amount of solar cells under the photon irradiation of the incident light wavelength λ The sub-efficiency EQE(λ) can be expressed as equation (1). EQE(λ)= Φ(λ) (1) In the formula. Φ(λ)---the photon flux of incident light per unit area, in joules (J); n --- The number of photogenerated carriers per unit area. It can be calculated by equation (2). n= Jph (2) ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38200-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 38200-2019_English as soon as possible, and keep you informed of the progress.
