Characterizing a Solar Cell
the intensity of the incident light influences cell current and power, but only modestly changes voltage. To alter the amount of incident light received at the cell, one might change the distance to the light source, place an obstacle (wire mesh) between the source and the cell, alter cell surface area, incident angle, or polarize the light.
