Quantum Efficiency (QE) is one of the key parameters of solar cells. It quantifies the efficiency of the conversion of light into electrons as a function of the wavelength of the incident light. The external quantum efficiency (EQE) is the fraction of incident photons on the solar cell that create electron-hole pairs in the absorber.
The "quantum efficiency" (Q.E.) is the ratio of the number of carriers collected by the solar cell to the number of photons of a given energy incident on the solar cell. The quantum efficiency may be given either as a function of wavelength or of energy.
The determination of the external quantum efficiency (EQE) is fundamental to photovoltaic research . This article proposes a fast conventional method to determine the external quantum efficiency (EQE) of a solar cell using a measuring bench (IPCE), such as the instruments and the measuring principle.
where P in (λ) and P abs (λ) are the powers of the incident light and absorbed light within the Si solar cell, respectively, at a wavelength λ. Using the quantum efficiency, integrated quantum efficiency, IQE, is defined as where h is Plank’s constant, c is the speed of light in the free space and I AM1.5 is AM 1.5 solar spectrum.
Internal quantum efficiency (IQE) is the ratio of the number of charge carriers collected by the solar cell to the number of photons of a given energy that shine on the solar cell from outside and are absorbed by the cell. The IQE is always larger than the EQE in the visible spectrum.
