Abstract

The invention discloses a cooling system of a concentrating perovskite laminated solar cell. Liquid water is used as a cooling working medium, and a constant-temperature water tank, a water pump and a channel coupling jet heat sink are sequentially connected through a liquid pipeline according to the water flow direction to form a cooling loop; the channel coupling jet flow heat sink comprises a jet flow cavity, a jet flow cavity inlet, a jet flow pore plate, an impact cavity, an impact cavity outlet and a channel type heat sink; the jet flow pore plate is arranged between the jet flow cavity and the impact cavity; the jet cavity inlet is located in the side face of the jet cavity. The channel type heat sink is arranged at the bottom in the impact cavity and corresponds to the jet flow pore plate; the impact cavity outlet is positioned on the side of the impact cavity; and an inorganic solar cell is packaged and fixed on the outer surface of the impact cavity. In addition, the invention also discloses a concentrating perovskite laminated solar cell device. According to the invention, the high-pressure jet flow formed by the liquid working medium in the cooling system passing through the jet flow hole impacts the channel heat sink, and the heat generated on the inorganic solar cell is taken away to realize rapid cooling, so that the stability and conversion efficiency of the whole photovoltaic power generation system are effectively improved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a cooling system and a solar cell device for concentrating perovskite laminated solar cells. Background technique [0002] As one of the new energy sources that has attracted much attention, solar energy has gradually been applied in various fields due to its clean, renewable and abundant resources. Solar power generation is one of the most mainstream and convenient ways to utilize solar energy at present. Concentrating photovoltaic power generation technology replaces high-cost semiconductor materials with low-cost concentrating structures, which greatly reduces the cost of photovoltaic power generation. It is a solar energy utilization technology that reduces consumables, saves costs, and improves the power generation efficiency of solar cells. The core component of the photovoltaic system is the solar cell, and the inorganic solar cell is currently the most mature and pla...
