External Quantum Efficiency Solar cell (photoelectric material) spectral response test, also known as quantum efficiency QE (Quantum Efficiency) test, or photoelectric conversion efficiency IPCE (Monochromatic Incident Photon-to-Electron Conversion Efficiency) test, etc., in a broad sense, is to measure the photoelectric properties of solar cells (photoelectric materials) under different wavelengths of light conditions. The so-called photoelectric properties include: photocurrent, photoconductivity, etc.
PVE300 Test the spectral response of solar cells, or quantum efficiency QE ( Quantum Efficiency ) test, or photoelectric conversion efficiency IPCE (Monochromatic Incident Photon-to-Electron Conversion Efficiency) Testing, etc. With the optional integrated range, it is also possible Measurement Internal quantum efficiency ( IQE ), as well as sampling the reflectance and transmittance. In a broad sense, it is the measurement of the photocurrent characteristics of optoelectronic materials under different wavelengths of light.
based on Bentham The company's professional technology and 25 Years of industry experience, PVE300 It can provide analytical data quickly and accurately and is a well-known international brand that has been tested by the market and widely used.
