About Residential photovoltaic thin-film modules
Thin-film solar panels use a 2nd generation technology varying from the crystalline silicon (c-Si) modules, which is the most popular technology. Thin-film solar cells (TFSC) are manufactured using a single or multiple layers of PV elements over a surface comprised of a variety of glass.
There are several types of materials used to manufacture thin-film solar cells. In this section, we explain the different types of thin-film solar panels regarding the materials used for the cells.
Thin-film solar panels have many interesting applications, and they have been growing in the last decade. Below you will find some of the most popular applications for thin-film.
Before comparing the different types of thin-film solar panels against crystalline silicon solar panels (c-Si), it is important to remark that there are two main types, monocrystalline.
Thin-film solar panels have many pros, while only holding a few cons to them. These are the most important pros and cons of this technology. There are four main types of thin-film solar panels: amorphous, cadmium telluride, copper gallium indium diselenide, and organic solar panels. Amorphous solar panels are more flexible but less efficient than other types of thin-film solar panels.

6 FAQs about [Residential photovoltaic thin-film modules]
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).
What are thin-film photovoltaic (PV) modules?
Thin-film photovoltaic (PV) modules are among the main alternatives to silicon modules in commercial solar energy systems. Thin-film technologies account for a small but growing share of the global solar market and are expected to grow at a compound annual growth rate of 23% from 2020-2025.
How efficient are thin-film photovoltaic panels?
Efficiency has been these panels’ biggest challenge and varies between the types of thin-film photovoltaic panels, but it has improved over time. In 2015, Solar Frontier, the world’s largest copper indium selenium (CIS) solar energy provider, achieved a 22.3% conversion efficiency.
What is a CIGS thin-film solar panel?
A CIGS thin-film solar panel is a type of thin-film module that uses Copper Indium Gallium Selenide (CIGS) as the main semiconductor material for the absorber layer. This technology is being popularized for various applications such as utility-scale installations, Building-Integrated Photovoltaics (BIPV), PV rooftops, and flexible thin-film solar panels.
What are the different types of thin-film solar cells?
Let’s take a closer look at the four most common types of thin-film solar cells: Amorphous silicon (a-Si) solar is the oldest film-thin technology, making it the most well-developed type of thin-film PV tech. This non-toxic panel uses a chemical vapor deposition to place a thin silicon layer onto the glass, plastic or metal base.
Are thin-film solar panels better than monocrystalline solar panels?
While thin-film solar panels are cheaper than monocrystalline and polycrystalline silicon panels, they are much less efficient and have lower power capacity. Efficiency has been these panels’ biggest challenge and varies between the types of thin-film photovoltaic panels, but it has improved over time.
