The quantum efficiency of a silicon solar cell. Quantum efficiency is usually not measured much below 350 nm as the power from the AM1.5 spectrum contained in such low wavelengths is low. While quantum efficiency ideally has the square shape shown above, the quantum efficiency for most solar cells is reduced due to recombination effects.
"Internal" quantum efficiency refers to the efficiency with which photons that are not reflected or transmitted out of the cell can generate collectable carriers. By measuring the reflection and transmission of a device, the external quantum efficiency curve can be corrected to obtain the internal quantum efficiency curve.
The quantum efficiency may be given either as a function of wavelength or of energy. If all photons of a certain wavelength are absorbed and the resulting minority carriers are collected, then the quantum efficiency at that particular wavelength is unity. The quantum efficiency for photons with energy below the band gap is zero.
The first report on the efficiency of Quantum Dot Sensitized Solar Cells (QDSSCs) was 0.12%. As of today, the efficiency is reported as 18.1 %, and further, the researchers are working to improve the efficiency of QDSSCs. 1. Introduction Energy is an essential part of modern life, leading to ever-increasing consumption across the world.
For example, quantum physics facilitates the design of tandem solar cells, which incorporate multiple semiconductor layers with varying bandgaps to capture a broader spectrum of sunlight. This maximizes light absorption and mitigates losses due to thermalization, enabling higher energy conversion efficiency.
