The utility model provides a double glass photovoltaic assembly, including glass cover plate, upside encapsulated layer, photovoltaic cell cluster, downside encapsulated layer and the backplate glasswho from top to bottom stacks gradually the setting, the upside encapsulated layer with the at least one POE layers that are multilayer structure of downside encapsulated layer. Compared with the prior art, the utility model discloses a multilayer structure's POE layer replaces traditional EVA, can the improvement with glass cover plate and backplate glass's adhesion strength, avoid poor, the easydelaminating scheduling problem of adhesion stress, has improved the mobility and has just helped improving peel strength. 本实用新型提供种双玻光伏组件，包括由上而下依次层叠设置的盖板玻璃、上侧封装层、光伏电池串、下侧封装层及背板玻璃，所述上侧封装层和所述下侧封装层的至少者为多层结构的POE层。与现有技术相比，本实用新型通过多层结构的POE层取代传统的EVA，可改善与盖板玻璃和背板玻璃的粘结强度，避免粘结力差、容易脱层等问题，提高了流动性且有助于改善剥离强度。
