Problems solved by technology

The single cell module in the perovskite solar cell module can be easily replaced, thereby solving the problem that if a single perovskite cell module is damaged during use, it will affect the power generation performance of the overall module, and the structure of the present invention has only one substrate at the bottom, and does not require Fill the surrounding area with additional adhesive film, and because the thickness of the battery itself is only micron level after removing the glass substrate, only one layer of filling layer (thickness 0.4~0.6mm) needs to be set between the battery sheet and the substrate, which solves the problem in the existing module structure Problems requiring thicker and wider fill layer material with better water blocking effect

Abstract

The invention provides a perovskite solar cell module and a packaging method thereof. The cell module comprises a bottom substrate, a plurality of perovskite solar cell modules which are connected inseries and in parallel and are arranged on the bottom substrate in a matrix manner, a peripheral packaging adhesive arranged at the periphery of each perovskite solar cell module, and a transparent substrate covering the perovskite solar cell modules, wherein a transparent conductive layer in sealed connection with the peripheral packaging adhesive is formed on the lower surface of the transparentsubstrate, so that each perovskite solar cell module is sealed in a packaging space defined by the bottom substrate, the transparent substrate and the peripheral packaging adhesive. Positive and negative connecting terminals of each cell are arranged outside the packaging adhesive on the four sides of each cell, so that series-parallel connection between the adjacent cells is realized, and independent packaging of each cell is realized at the same time, so that the packaging effect of the single cell can be enhanced, the overall packaging effect is good, and the single cell can be independently replaced when a fault occurs.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a perovskite solar cell module and a packaging method thereof. Background technique [0002] Since the invention of perovskite solar cells in 2009, based on the advantages of abundant earth reserves, simple preparation process, and high conversion efficiency, it has attracted extensive attention from researchers and industries in the field of solar power generation technology around the world, making it possible to realize cheap solar power generation. The core technology fully reflects its good commercialization prospects and great potential market value. However, the stability and device size scaling of perovskite solar cells have been the key problems restricting their high-efficiency commercial applications. At present, substantial progress has been made in the preparation technology of large-scale perovskite cells. However, in order to further prepare large-scale pero...
