This will be explained with the solar power generation module 10.

Referring to FIG. 1, a tubular solar power generation module 10 that produces power based on sunlight according to a preferred embodiment of the present invention includes a tube portion 100 and an inner or outer peripheral surface of the tube portion 100. It includes a solar power generation cell 200 provided in and a reflector 300 provided at the end of the tube part 100, and the solar power generation cell 200 is incident on the inside of the tube part 100. Power is produced through incident light, and power is produced again through reflected or scattered light reflected or scattered from the incident light by the solar power generation cell 200 and the reflector 300.

First, the tube portion 100 is prepared. The tube portion 100 is formed to have a straight or curved cross-section, supports the solar power generation cell 200 provided therein, and is damaged when an impact is applied to the solar power cell 200 from the outside. It serves to prevent dust or foreign substances from penetrating into the solar power cell 200.

Next, the solar power cell 200 is prepared. The solar power generation cell 200 is provided in all or part of the tube part 200 and serves to produce power based on sunlight incident on the inside of the tube part 100. At this time, the solar power generation cell 200 is used to generate solar power generation, which is a power generation method that converts light from the sun into electrical energy using the photoelectric effect. A detailed description of the conventional solar power generation method is omitted. do.
