Solar Cell Research & Optimization

Zahner’s CIMPS and QE/IPCE workstations, which utilize a combination of a Zennium workstation and external potentiostat powering a lightsource, are well-known within the solar PV research community as among the best equipment available to carry out the investigation of silicon solar cells (SC), dye sensitized SC, perovskite SC, Grätzel SC, organic photovoltaics (OPV), and other photoactive devices such as photo sensors. Determining power conversion efficiency, incident-photon-to-current-conversion efficiency IPCE, fill factor and charge extraction are common methods that can be run easily and reliably with our equipment.
