Characterization of Solar Cell by varying illumination

Article history Received: 27 November 2020 Received in revised form: 21 January 2021 Accepted: 26 January 2021 Available online: 31 January 2021 Abstract This work aims to confirm that the single-diode model of a monocrystalline cell can be used successfully also for thin-film solar cells when their basic parameters are calculated using the method of changing illumination. The authors describe the experimental procedure, in which I–V curves of thin-film solar cells are measured when illumination levels are changing. In experiments, a fully reflective 500 W solar simulator is used as an excellent broadband white light source, which provides the range of 0.01–10 Sun settings.
