2. SILICONE AS AN ENCAPSULANT

2.1. PROTECTIVE PROPERTIES

One of the primary applications of silicone in solar cells is as an encapsulant. By enveloping the photovoltaic components in a layer of silicone, manufacturers secure the cells against environmental hazards, which can cause significant degradation over time. Silicone’s outstanding durability helps to prevent moisture ingress and protects against the damaging effects of UV light. These protective properties ensure that the solar cells maintain their efficiency and structural integrity for years, often exceeding a 25-year lifespan guaranteed by manufacturers.

The encapsulation process with silicone involves a careful method of applying the silicone polymer, often in a liquid form, that cures to form a solid layer. This not only provides physical stability to the solar cells but also allows for flexibility. Traditional encapsulants, such as ethylene-vinyl acetate (EVA), can become brittle over time, leading to increased susceptibility to cracking. In contrast, silicone maintains its flexibility and can accommodate thermal expansions and contractions, a crucial characteristic given the varying temperatures that solar panels experience.
