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 ].
Considering the accessibility and cost, the main thin film deposition techniques used in photovoltaics are physical vapor deposition (PVD), chemical vapor deposition (CVD), chemical solution deposition and sol–gel [ 3 ]. 2. Crystalline silicon solar cells As mentioned above, c-Si is dominating the PV industry with a market share of 95%.
Solution processing is the traditional fabrication method for perovskite solar cells. Spin coating is the most common fabrication approach used in the laboratory, and it has the advantages of a simple process, with no requirement for expensive and complex vacuum systems.
The technique mainly used for these ARC/passivation layers is CVD, in particular, PECVD, LPCVD and ALD. PVD-sputtering is the main technique that is used for ITO layers in SHJ solar cells. The distinguishing feature between PVD and CVD is the states of vapor.
It involves the generation of electricity from sunlight shining through the front cover onto solar cells packaged into a solar module. As of May 2022, global PV installations have reached 1 TW.
