The answer to what solar panels are made of is simple: they're primarily built from silicon solar cells, a protective glass layer, an aluminum frame, wiring, and encapsulation materials.
A solar panel is a device that converts sunlight directly into electricity through a process called the photovoltaic effect. It is composed of multiple solar cells, typically made of silicon, that are interconnected and encased in a protective material.

US scientists developed a monocrystalline solar panel relying on “minicells” based on polysilicon on silicon oxide passivating contacts. The module works with laser light and can reportedly achieve a photoconversion efficiency of over 40% and an open-circuit voltage of 7 V.
Most residential panels convert about 20–23% of sunlight into usable electricity. Although that number may seem modest, it is enough to power homes efficiently when weather conditions cooperate.
While traditional solar panels can only capture sunlight with one sky-facing layer, bifacial solar panels use both sides of the equipment to absorb more of the sun's energy and produce larger amounts of emission-free electricity.
