Description
🟧 ModuLab XM Photoelectrochemical Test System
ModuLab PhotoEchem XM is a configurable platform product that is primarily focused on solar cell and photovoltaic research. The system, based upon Solartron Analytical’s world-leading experience in transfer function measurements, offers a high-quality measurement platform for characterizing a range of photoelectrochemical devices such as DSSC’s, Perovskite cells, and Photoanodes, noted Professor Laurie Peter, world-leading expert, University of Bath, UK. Professor Peter acted as scientific advisor during the development of the ModuLab PhotoEchem system and helped ensure the system met the requirements of the most demanding photovoltaic researchers in the market today.
ModuLab PhotoEchem XM includes a reference-grade potentiostat, frequency response analyzer (FRA), and PhotoEchem module that provide complete characterization of a wide range of solar cells and PV cells, including Perovskite and Dye Sensitized Solar Cells (DSSC). Additionally, the system can be used for the development of visible spectrum photoelectrochemical systems such as Iron-Oxide photo-splitting of water.
A key feature of this system is its ease of use, with data analysis requiring just one click of the mouse! For experienced users, ModuLab PhotoEchem XM offers the ability to develop new experiment types with the powerful step sequencer.
