A method for manufacturing solar cells is disclosed. The method includes forming an insulating material in a printable suspension along the at least one side edge of a solar cell, the insulating material in a printable suspension further adapted to form a protective film which reduces cracking near at least one side edge of the solar cell and improve structural integrity against mechanical stress. The protective film has an elastic modulus of at least 3 GPa, an elongation break point of at least 13 percent and a glass transition temperature of at least 250 degrees Celsius which provides additional structural support along the side edges, increasing the overall structural integrity, providing electrical insulation along the edges and improve the flexure strength of the solar cell.

The invention provides a polyester film for the protection of a back surface of a solar cell which, when applied to a silicon thin film solar cell, exhibits excellent durability even under high-temperature and high-humidity conditions and long term thermal stability. The polyester film (a) contains a polyester, as a main constituent, obtained by polymerization using a polycondensation catalyst containing aluminum and/or its compound as well as a phosphorus compound having an aromatic group in the molecule; (b) has a whiteness degree of 50 or higher; (c) contains 3 to 50% by mass of fine particles with a mean particle diameter of 0.1 to 3 m; and (d) has an acid value from not lower than 1 (eq/ton) and not higher than 30 (eq/ton).

Provided are a multi-layered film, a backsheet for a photovoltaic cell, a method of forming the same and a photovoltaic module. The multi-layered film may include a primer layer and a fluoropolymer coating layer formed by coating, and thus the fluoropolymer coating layer, which is a surface layer, may have excellent durability and weather resistance due to an inter-diffusion effect between materials in the respective layers, and a high interface adhesive strength with a substrate and the primer layer. In addition, in the preparation of the multi-layered film, a production cost may be reduced, productivity may be increased, and degradation in quality of a product caused by thermal transformation or heat shock may be prevented. The multi-layered film may be effectively used as a backsheet for various photovoltaic modules.

An encapsulant of a photovoltaic module, intended for coating a photovoltaic cell (10), including: a copolymer of ethylene-alkyl acrylate, the melt flow index (MFI) of the copolymer being 1 g/10 min to 40 g/10 min; and a silane making up 0.1% to 0.5% of the weight of the composition; wherein the encapsulant also includes a cross-linking agent making up 0.1% to 0.5% of the weight of the composition and wherein the copolymer makes up at least 99% of the weight of the composition. Also, a use of such an encapsulant in a photovoltaic module as well as to a photovoltaic module including such an encapsulant.
