Abrégé

The present application relates to the technical field of solar cells, and discloses a solar cell encapsulation structure, comprising: a battery assembly comprising a front glass, a cell film layer, and a back glass that are sequentially stacked; an edge sealing body, which is connected to the front glass and the back glass, and defines, together with the front glass and the back glass, a space for protecting the cell film layer; and a busbar, attached to the film surface on the side of the cell film layer facing away from the front glass. A gap is arranged between the outer contour edge of the side of the cell film layer corresponding to the busbar and the edge sealing body. Compared with arranging the busbar between the cell film layer and the edge sealing body, in the solar cell encapsulation structure provided by the present application, the busbar is attached to the film surface on the side of the cell film layer facing away from the front glass, preventing the busbar from occupying the installation space of the cell film layer, and thus increasing the effective power generation area of the cell film layer, improving the photoelectric conversion efficiency of the battery assembly.

Abrégé

The present application provides a photovoltaic module and a manufacturing method therefor. The photovoltaic module comprises a cell, a back plate, a sealing body, and an electrical connecting member, wherein the back plate is arranged on one side of the cell, and the back plate is at least provided with at least one lead-out hole; at least part of the sealing body is accommodated in the lead-out hole; an extension portion covering the periphery of the lead-out hole is formed on the sealing body; and one end of the electrical connecting member is electrically connected to the cell, and the other end of the electrical connecting member passes through the sealing body and extends out of the lead-out hole. According to the present application, by providing a sealing body which is provided with an extension portion covering the periphery of a lead-out hole, under the action of multiple waterproof measures, the requirement of a perovskite photovoltaic module on the water vapor barrier performance is met, the problem of water blocking failure at the hole plugging position caused by existing design is solved, the outdoor service life of the photovoltaic module is prolonged, and good development potential is achieved.

Abrégé

The present application relates to the technical field of photovoltaics. Disclosed is a perovskite solar cell. The perovskite solar cell provided in the present application comprises a substrate layer, a transparent conductive layer, a cell layer, an electrode layer and conductive adhesive tapes, wherein one side surface of the substrate layer has a first area, a second area and a third area, and the cell layer is located on the side surface, which is away from the substrate layer, of the transparent conductive layer located in the third area; the electrode layer is located on the side surface of the transparent conductive layer that is away from the substrate layer; and the conductive adhesive tapes are located on the side surface, which is away from the substrate layer, of the electrode layer in the first area and the second area, and the conductive adhesive tapes are arranged spaced apart from the cell layer. In the perovskite solar cell provided in the present application, an electrode layer is not prone to demolding. Moreover, since the conductive adhesive tapes are not stacked on the cell layer, decomposition or phase change of part of the cell layer caused by the conductive adhesive tapes participating in lamination and packaging is also avoided. Therefore, the high-perovskite solar cell has relatively good electrical properties and reliability.
