儀器簡介：

The new QE/IPCE measurement kit allows researchers to measure Quantum efficiency (QE) and Incident Photon to
Charge Carrier Efficiency (IPCE) measurement for solar cells, detectors, or any other photon-to-charge converting device. We
selected the most suitable components for your measurements needs. trusttech is an industry leader in light sources and spectroscopy products.

What are QE and IPCE?
Quantum efficiency (QE) and Incident Photon to Charge Carrier Efficiency (IPCE) indicates the ratio of the number of photons
incident on a solar cell to the number of generated charge carriers. Quantum efficiency is a measure of external efficiency, while IPCE considers the internal efficiency; that is, the photons reflected back from the surface of the cell are not considered.
The QE/IPCE measurements are critical especially during the materials research and cell design stagebecause it is of great importance for a device to have an optimal spectral response at the point at which the spectral component of the sunlight is abundant. The system is built by an industry leader in light sources and spectroscopy, so you can rely on our expertise to ensure accuracy of the measurement.

How to Measure QE and IPCE?
The key to accurately measure the QE/IPCE of a solar cell is to quantify the intensity of monochromatic light incident to the
device under test and how much current is generated. We provide the most important components, which are the most
common building blocks of a QE/IPCE system that will allow you to quickly set up the experiment.

太陽能電池量子效率QE/ IPCE介紹
太陽能電池量子效率QE (Quantum efficiency)和太陽能電池IPCE(Incident Photon to Charge Carrier Efficiency)表示入射到太陽能電池表面的光子數(shù)目與太陽能電池產(chǎn)生的電荷載流子數(shù)目比率。太陽能電池量子效率QE (Quantum efficiency)測試是對太陽能電池外部效率的測量，而太陽能電池IPCE(Incident Photon to Charge Carrier Efficiency)測試是對太陽能電池內部效率的測試，也就是說太陽能電池表面反射的光子是不被考慮的。
太陽能電池量子效率QE/ IPCE測試在太陽能電池材料研究和太陽能電池設計中非常關鍵特殊，因為，對于太陽能電池，在太陽光譜組成分布較強的光譜位置上具有**的光譜響應是極其重要的。該太陽能電池量子效率QE/ IPCE測試設備是以光源和光譜學前沿技術為基礎的，所以，您可以信任它的專業(yè)測試準確性。
