When sunlight strikes a solar cell, electrons in the silicon are ejected, which results in the formation of “holes”—the vacancies left behind by the escaping electrons.
Crystalline silicon cells are made of silicon atoms connected to one another to form a crystal lattice. This lattice provides an organized structure that makes conversion of light into electricity more efficient. Solar cells made out of silicon currently provide a combination of high efficiency, low cost, and long lifetime.
Part 1 of the PV Cells 101 primer explains how a solar cell turns sunlight into electricity and why silicon is the semiconductor that usually does it.
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.
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon.
The greatest silicon solar cell achieved a 26.7 per cent efficiency on a lab scale, whereas today's standard silicon solar cell panels run at roughly 22 per cent efficiency. As a result, many current solar research programmes are devoted to identifying and developing more effective sunlight conductors.
