Effect of Illumination Intensity on Solar Cells Parameters
When solar cells are utilized for indoor applications or integrated into a building, they are generally exposed to variable irradiance intensity.

IV Curve
The IV curve of a solar cell is the superposition of the IV curve of the solar cell diode in the dark with the light-generated current.1 The light has the effect of shifting the IV curve down into the fourth quadrant where power can be extracted from the diode.

Bypass Diodes
Under normal operation, each solar cell will be forward biased and therefore the bypass diode will be reverse biased and will effectively be an open circuit. However, if a solar cell is reverse biased due to a mismatch in short-circuit current between several series connected cells, then the bypass diode conducts, thereby allowing the current ...
