Description

High-efficiency and energy-saving solar panels for both light and heat

technical field

The utility model relates to the field of solar cells, in particular to a high-efficiency and energy-saving solar cell panel for both light and heat.

Background technique

A solar panel is a device that converts solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon", but due to the high production cost , so that its general use still has certain limitations. At present, there are two ways of solar power generation: one is light-heat-electricity conversion, and the other is light-electricity direct conversion. The light-heat-electricity conversion method uses the thermal energy generated by solar radiation to generate electricity. Generally, the solar collector converts the absorbed heat energy into working medium steam, and then drives the steam turbine to generate electricity.

The disadvantage of the existing technology is that there is currently no device that can simultaneously realize light-heat-electricity and light-electricity solar panels. For example, the patent number CN201620435820.8 discloses a high-efficiency energy-saving solar battery for both light and heat. The plate includes a convex lens and a solar cell panel, a second heat collecting device and a second heat conduction device are installed inside the solar cell panel, a first heat conduction device is installed under the solar cell panel, and a The first heat collecting device, a water tank is installed under the first heat collecting device, and the convex lens is installed on the solar panel.

The above schemes only use this solar heat collector, and then use the collected heat directly to heat the water in the water tank, so that both light and heat can be used, thereby making full use of solar energy and indirectly saving non-recyclable resources; However, if the water is not used in time after heating, it will also cool down, resulting in waste of energy, and the energy is not directly used to convert it into electrical energy.

In response to the above situation, our company has proposed a patent application for an energy-saving solar panel that uses both light and heat. In this plan, it is proposed to use light energy and heat energy to generate electricity at the same time, but considering that the incident angle of light changes with time , which will lead to insufficient power generation in this scheme, so our company proposes a further improvement scheme on this basis.
