NOVELTY - The photovoltaic module (100) comprises a photovoltaic member (120) having a side edge, a moisture-resistant layer (140) adhered to the side edge, a mounting frame (170) covering the moisture-resistant layer, and a buffer layer (160) disposed between the moisture-resistant layer and the mounting frame. The buffer layer is made of material selected from a group consisting of polypropylene-based polymer, polyethylene-based polymer, polyurethane-based polymer, ethylene-vinyl-acetate-based resin and a combination of the polymers.    USE - Photovoltaic module for converting solar energy to electrical energy.    ADVANTAGE - The buffer layer functions as a shock absorber to protect the edge of the photovoltaic member from being fractured or broken, and suitable buffer layer materials are selected to avoid chemical interaction between moisture-resistant layer and the buffer layer. The silicone sealant enables to withstand a temperature of -40 to 90 degrees Celsius. First and second sealants are used to prevent water or water vapor from migrating into the photovoltaic member through gaps existing between the mounting frame and the top/bottom surfaces of the photovoltaic member, and thus to provide a better reliability of the photovoltaic module. The photovoltaic module can withstand wind snow, static or ice loads. The photovoltaic module presents a better moisture barrier and more cost-effective module. The buffer layer can be assembled with the mounting frame without additional pre-fabrication process, thus, photovoltaic module is more cost-effective and has better reliability.    DETAILED DESCRIPTION - The moisture-resistant layer is made of butyl rubber, silicone or polyurethane, and the buffer layer has a foam structure. The mounting frame is made of plastic, such as polyphenylene oxide (PPO) or polyphenylene ether (PPE), or metal, such as aluminum or stainless steel.
