At present, carbon emissions mainly exist in the energy field, and the low-carbon transformation of energy has become the core content of achieving carbon neutrality. In order to build a clean, low-carbon, safe and efficient energy system, control the total amount of fossil energy, improve energy utilization efficiency, and promote the alternative action of renewable energy, the low-carbon power system is the basis and main way. Perovskite solar cells are the next generation of solar energy technology, due to its high theoretical conversion efficiency, low cost, adjustable structure and other advantages, suitable for various scales and complex environments, easy to integrate building integrated photovoltaic, can provide a new solution for “light storage direct soft”, “source network load storage” integration and other scenarios. It has great potential in the field of distributed photovoltaic, which can realize nearby power generation, nearby grid-connection, nearby conversion, and nearby use, and solve the problem of power loss in voltage boost or long-distance transportation, and has broad application prospects.
