Low-cost Instrument for Characterization of Solar Cells
A low cost home-made instrument for characterization of solar cells has provided reliable data for drawing current versus voltage curves of the solar cells under test. The low cost instrument can be an alternative to high-cost standard instruments used for testing solar cells by determining light-to-electricity conversion efficiencies of the solar cells. Calibrations of commercially available mini-solar panels (silicon cells) with respect to a standard pyranometer (SolData) show that the mini-panels can measure solar radiation.
