Material Characterisation

infinityPV ApS offers a versatile range of source measure units (SMUs) enabling testing of many solar cells in the same setup (from 1 to 40 channels) using a unique series multiplexers (MUXs) that cover from low voltage to high voltage 1kV or above. It is all controlled by powerful software enabling determination of power conversion efficiency and the following of performance over time when solar cells are subjected to different test conditions. This could for instance be following the ISOS testing protocols in connection with our ISOSun series of solar simulators. Our multiplexed units enable access to the device under test at all times (except when periodically tested by the SMU). This allows the user to control the electrical conditions of the devices under test at all times. This could be electrical stress through forward or reverse bias, a short circuit, open circuit, or a load. It is also possible to add maximum power point tracking units (MPPTUs) to each channel such that the device on that channel is subject to maximum power point tracking. When combined with our ISOSun, ISOS-L-3 chamber, weather station and software a complete turnkey system is at hand.
