Solar cells are described as being photo-voltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photo detector, detecting light or other electromagnetic radiation near the visible range or measuring light intensity.
In this section, Holmarc introduces some apparatus that are helpful for the study of solar cells with a modified approach.
Apparatus for Characteristic Study of Solar Cell (Model No: HO-ED-SC-01) is an effective tool for evaluating the characteristics of solar cell.
Spectral response is the ratio of the current generated by the solar cell to the power incident on the solar cell or a detector.
The spectral responsivity or quantum efficiency (QE) is essential for understanding current generation, recombination, and diffusion mechanisms in photovoltaic devices.
Holmarc’s Thermally stimulated current (TSC) spectrometer is used to study energy levels in semiconductors or insulators, especially solar cells.
