4 FAQs about Solar panel film

Are PowerFilm solar panels cadmium free?

The amount of silicon used in PowerFilm solar panels is as low as 1 percent of the amount used in traditional solar panels. PowerFilm has a strong environmental profile and is cadmium free. Single and tandem junction devices are manufactured. Finished panels are encapsulated in materials appropriate for the application environment.

What are thin-film solar panels?

Thin-film solar panels are manufactured using materials that are strong light absorbers, suitable for solar power generation. The most commonly used ones for thin-film solar technology are cadmium telluride (CdTe), copper indium gallium selenide (CIGS), amorphous silicon (a-Si), and gallium arsenide (GaAs).

How much does a thin-film solar panel cost?

A 3.5 kilowatt peak (kWp) thin-film solar panel system costs about £3,500, which is much less than the cost of a traditional solar panel system of the same size. However, this lower cost comes with trade-offs: thin-film panels offer much lower efficiency and a shorter lifespan. To learn more, check out our guide to solar panel costs.

What materials are used for thin-film solar panels?

There are four different types of materials used for thin-film solar panels: Cadmium telluride is the most commonly used substrate in manufacturing thin-film panels. In fact, it holds 50% of market share. These panels have an efficiency range between 9% and 11%, but some have seen up to 18.7% efficiency ratings.
