High-efficiency and low-cost perovskite solar cell products are prepared by an all-solution printing process. A reliable packaging process reduces battery performance loss and can achieve stable outdoor operation. The photoelectric conversion efficiency of the 125mm×125mm perovskite module is 15.3%; the current module size is 620mm×590mm; the supporting material of the battery and 99.88% of the lead can be recycled to prepare perovskite solar cells, and the same photoelectric conversion efficiency as the new material can be achieved. With low production costs, small equipment investment, abundant raw materials, simple process, and little environmental pollution, perovskite batteries can be recycled and reused. The energy recovery period is about 1 month, and the minimum carbon emission per kilowatt hour of electricity is only 13.4 grams. As a distributed energy solution suitable for cities, it can effectively reduce building energy loads.
