Low cost light source
SA05SS is a high stability LED based light source, low cost tool for organic, dye-sensitized, polymer and perovskite solar cell testing. It is available in two versions: without or with temperature-controlled measuring table. SA05SS is able to be controlled, light intensity/mode and table temperature, by notebook computer through USB 2.0 port. Low cost systems suitable both for research as well didactic purposes for characterization of solar cells.
