Perovskite Solar Cells: An In-Depth Guide

Perovskite solar cell technology is considered a thin-film photovoltaic technology, since rigid or flexible perovskite solar cells are manufactured with absorber layers of 0.2- 0.4 μm, resulting in even thinner layers than classical thin-film solar cells featuring layers of 0.5-1 μm. Comparing both technologies provides an interesting contrast between them.

How a Solar Cell Works

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. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.

Introduction to Solar Cells

It is the building block of a solar panel and about 36–60 solar cells are arranged in 9–10 rows to form a single solar panel.
