Abstract:
Photovoltaic (PV) cells are semiconductor devices that produce power when illuminated by a light source. The energy created depends on many factors. Light intensity, PV cell temperature, and wavelength of incident light are three factors which can vary for the many uses of PV cells. These three sets of conditions were used to examine the short circuit current (Isc) and the open circuit voltage (Voc) of the PV cells. The Isc was linearly dependent on light intensity. The Voc was nearly linearly dependent on light intensity for low voltages and logarithmicly with light intensity for higher voltages. Voc and Isc responses both showed similarity to the theoretical spectral response curve for the wavelength of incident light. The Voc was linearly dependent on the temperature of the cell. All of the data is explained using PV cell theory.
