Artwork: How a simple, single-junction solar cell works. A solar cell is a sandwich of n-type silicon (blue) and p-type silicon (red). It generates electricity by using sunlight to make electrons hop across the junction between the different flavors of silicon: When sunlight shines on the cell, photons (light particles) bombard the upper surface.
Interaction between the crystalline silicon cells on the panel with the outside environment. LID can last days or over a week. Direct light-induced degradation (DLID). Direct exposure to sunlight during the initial setup period can cause the electronics within the photovoltaic cells to warp or buckle from the heat. DLID can last a few hours.

A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, kn…
A solar cell is a device that converts light into electricity via the ''photovoltaic effect''.
