Water circulating solar cell

Abstract

The invention relates to a water circulating solar cell which comprises a solar cell panel, and a cooling tube arranged inside the solar cell panel, wherein a liquid inlet and a liquid outlet are respectively arranged at two side ends of the solar cell; the liquid inlet is communicated with one end of the cooling tube; the liquid outlet is communicated with the other end of the cooling tube; the liquid inlet is connected with a liquid inlet pipeline; the liquid outlet is connected with a liquid outlet pipeline; a pump and a liquid storage tank are sequentially connected between the liquid inlet pipeline and the liquid outlet pipeline; and the cooling tube is adhered to the inner surface of the solar cell panel. The water circulating solar cell adopts a wave-shaped cooling tube; the temperature of the solar cell can be reduced in a working process of the solar cell; the photoelectric conversion efficiency is improved; and light utilization efficiency is improved.

Description

technical field [0001] The invention relates to the field of photovoltaic modules, in particular to a water cycle solar cell. Background technique [0002] Traditional fuel resources are being depleted day by day, and the harm caused by their uninterrupted development to the environment has become increasingly prominent. More and more countries have begun to develop solar energy resources and seek new energy sources for economic development. In practical applications, more than 80% of the solar energy projected on the surface of the photovoltaic cell by sunlight is reflected or converted into heat energy. Since the sunlight shines on the battery, the battery under the light will emit high Generally, when the solar cell works at an average outdoor temperature of 20°C, the normal operating temperature of the battery is about 40-45°C. When the temperature rises, it is easy to cause the photoelectric conversion efficiency to drop. 1 degree, the photoelectric conversion efficien...

In practical applications, more than 80% of the solar energy projected on the surface of the photovoltaic cell by sunlight is reflected or converted into heat energy. Since the sunlight shines on the battery, the battery under the light will emit high Generally, when the solar cell works at an average outdoor temperature of 20°C, the normal operating temperature of the battery is about 40-45°C. When the temperature rises, it is easy to cause the photoelectric conversion efficiency to drop. 1 degree, the photoelectric conversion efficiency drops by 3-5%
