Deputy Chief Executive Energy Planning and Development Division Energy Market Authority Director Centre of Sustainable Building & Construction Building and Construction Authority The sun delivers its energy to us in two main forms: heat and light. There are two main types of solar power systems, namely, solar thermal systems that trap heat to warm up.

What are thin-film solar panels?
Thin-film solar panels use a 2 nd 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, plastic, or metal.
How are amorphous silicon (a-Si) thin-film solar panels made?
There are two routes to manufacture amorphous silicon (a-Si) thin-film solar panels, by processing glass plates or flexible substrates. Efficiency for a-Si solar cells is currently set at 14.0%. Disregarding the route taken to manufacture amorphous silicon (a-Si) thin-film solar panels, the following steps are part of the process:
How thick is PowerFilm solar panels?
The substrate is as thin as 1mil (0.025mm) thick. Amorphous silicon is the absorber layer in the solar panels. 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.
In 1980, researchers finally achieved a 10% efficiency, and by 1986 ARCO Solar released the G-4000, the first commercial thin-film solar panel. Thin-film solar panels require less semiconductor material in the manufacturing process than regular crystalline silicon modules, however, they operate fairly similar under the photovoltaic effect.
What is the difference between crystalline silicon and thin-film solar panels?
There are many differences regarding crystalline silicon and thin-film solar panel technology. One important difference is how the temperature affects the efficiency of each technology, c-Si solar cells are more affected by temperature than thin-film technologies.
CdTe thin-film solar panels reached a 19% efficiency under Standard Testing Conditions (STC), but single solar cells have achieved efficiencies of 22.1%. This technology currently represents 5.1% of the market share worldwide, falling second only under crystalline silicon solar panels that hold 90.9% of the market.
