UV/Visible/NIR Spectrophotometer (Shimadzu 3600)

UV Visible-3600 is a spectrophotometer which determines the spectral response of a material with three detectors, consisting of a PMT (photomultiplier tube) for the ultraviolet and visible regions and InGaAs and cooled PbS detectors for the near-infrared region. The wide wavelength range of 185 to 3,300 nm enables measurement across the ultraviolet, visible, and near-infrared regions. This instrument can perform spectrophotometry for a variety of applications.

Solar Cell External Quantum Efficiency measuring device IPCE (EQE)

This system is suitable for measuring EQE (External Quantum Efficiency) of solar cell. Quantum efficiency (QE) – also referred to as 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.
In order to understand the conversion efficiency as a function of the wavelength of light impingent on the cell, the QE/IPCE measurement is critical for materials research and cell design.
