In principle, most active materials in solar cell are sensitive to e.g. ambient oxygen and moisture, UV radiation, heat, and even mechanical threats from the environment, and the active layers need to be protected from those phenomena with suitable encapsulation.
The effects of harmful light, such as UV light, can be prevented by using composite encapsulation systems. One of the most common methods for UV protection is using semiconductor nanoparticle layers, such as zinc oxide (Aljaiuossi et al., 2019) and TiO 2 (Zhu et al., 2021) layers, as the solar cell front layer.
Thermoplastic polyolefin & glass backsheet and butyl rubber edge sealant is a possible option for PSC encapsulation. The encapsulant was applied with 150 °C vacuum lamination, and a PSC with certain structure withstood the process without losses in cell performance, however the encapsulation method results in a rigid solar cell;
Crystalline silicon solar cells dominate the commercial PV market sovereignly: 95% of commercially produced cells and panels were multi- and monocrystalline silicon, and the remaining 5% were cadmium telluride (CdTe), copper indium gallium selenide (CIGS) and amorphous silicon (a-Si) (Photovoltaics Report - Fraunhofer ISE, 2020).
Encapsulation has often a direct link to solar cell stability. The most relevant industrial stability standards for PV modules are issued by the International Electrotechnical Commission (IEC) and have been summarized in the IEC 61251 standard that entails several detailed and interconnected accelerated aging tests (Holzhey and Saliba, 2018).
Organic solar cells (OSCs) use small organic molecules and conductive organic polymers for light absorption, charge separation and charge transport. The molecules employed in OSCs are solution-processable and cheap, and the advantages of OSCs are mechanical flexibility and low-cost fabrication (Bazaka et al., 2017a, Nelson, 2011).
