Photovoltaic background, technology
The photovoltaic effect is dependent on two physical values (see Fig. P5)– irradiance and temperature: . As irradiance E (W/m 2) increases, so do the current and power produced by the cell; As the temperature (T°) of the cell increases, the output voltage decreases significantly, the current increases only slightly, so overall the output power decreases.
