One of the challenges for engineers is figuring out how to implement a protective layer of coating onto these thin-film solar cells. Vacuum coating technology helps to address this concern by depositing a tough, protective layer on the surface while preserving the hardware, integrity, and performance of the cell.
These solar cells work by incorporating several layers of semiconductor materials, such as amorphous silicon and gallium arsenide, that absorb photons from the sun in order to create electricity. One of the challenges for engineers is figuring out how to implement a protective layer of coating onto these thin-film solar cells.
This paper reviews the latest applications of antireflection optical thin films in different types of solar cells and summarizes the experimental data. Basic optical theories of designing antireflection coatings, commonly used antireflection materials, and their classic combinations are introduced.
Let’s take a look at the coating technology behind them. Coating technology is an important factor in the production of photovoltaic cells, as it helps to increase the efficiency of solar energy capture. In fact, coatings can enhance the performance of these devices across a range of applications.
In 1981, Mickelsen and Chen demonstrated a 9.4% efficient thin-film CuInSe2/CdS solar cell. The efficiency improvement was due to the difference in the method of evaporating the two selenide layers. The films were deposited with fixed In and Se deposition rates, and the Cu rate was adjusted to achieve the desired composition and resistivity.
Another important application of thin films in PV is the antireflection coating (ARC) on the surface of solar glass where the light first reaches the solar panels. Currently, single-layer antireflection coated solar glass has a dominant market share of 95% compared to glass with other coatings or no coating, for Si PV modules [ 2 ].
