Description

Technical Field

[0001] The utility model relates to the technical field of perovskite photovoltaics, in particular to a perovskite photovoltaic component. Background Art

[0002] In the current solar cell field, lead (Pb)-based perovskite solar cells have achieved a high-efficiency photoelectric conversion efficiency of more than 26% and a stability of more than 10,000 hours, with great commercial potential. However, in actual use, the sealing layer of lead-based perovskite solar cells will age and water will enter the lead-based perovskite solar cells, causing MAPbI3 to undergo a spontaneous irreversible dissolution process after encountering H2O. The typical decomposition products are CH3NH2, HI and PbI, which then flow out of the lead-based perovskite solar cell, causing lead leakage and causing serious pollution to the environment. Therefore, it is necessary to use a device to detect leakage of lead-based perovskite solar cells.

[0003] A perovskite photovoltaic module and photovoltaic device provided by publication number CN220693636U include: a substrate, a perovskite photovoltaic cell located on the surface of the substrate, and a cover plate located on the side of the perovskite photovoltaic cell away from the substrate. A first adhesive layer located on the surface of the substrate and extending along a first direction is connected to the cover plate to form a cavity, and the perovskite photovoltaic cell is located in the cavity and bonded to the first adhesive layer. A lead ion sensor located on the surface of the substrate and on the side of the first adhesive layer away from the perovskite photovoltaic cell is also bonded to the first adhesive layer.

[0004] However, when the above-mentioned perovskite photovoltaic modules and photovoltaic devices are in use, after the lead ion sensor detects a lead leakage, manual inspection or drone photography is required to observe the color change of the lead ion sensor to determine the lead leakage. However, perovskite photovoltaic modules are usually deployed in large numbers, and judging lead leakage in this way is inefficient and prone to errors. Summary of the invention

[0005] The purpose of the utility model is to provide a perovskite photovoltaic module to solve the problems raised in the above background technology.

When the perovskite photovoltaic cell is invaded by water, the water contacts the conductive ring 1 and the conductive ring 2 at the same time, causing the signaling module to send a lead leakage signal.

[0010] Preferably, the rechargeable battery and the perovskite photovoltaic cell are connected by setting a charging line, so that the perovskite photovoltaic cell can charge the rechargeable battery.

[0011] Preferably, a water-absorbing film is provided on the conductive ring 1 and the conductive ring 2, and the water-absorbing film is used to retain water above the conductive ring 1 and the conductive ring 2.
