Embodiment Construction

[0014] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0015] refer to figure 1 , a device for generating electricity using solar energy, the main structure includes a circulation pipeline 1 and a hydroelectric generator 4 . The circulation pipeline 1 is filled with water or other heated convective water. The circulation pipeline 1 is partially submerged below the sea surface 10 and partially exposed above the sea surface 10 . The part of the circulation pipeline 1 submerged below the sea surface 10 forms a cooling water tank 3; the part of the circulation pipeline 1 exposed above the sea surface 10 forms a heat absorption tank 2, and the outer periphery of the heat absorption tank 2 is covered with a heat absorption layer. The top of the heat absorption tank 2 forms a water outlet, and the bottom forms a water inlet. A water turbine generator 4 is arranged near the water outlet of the heat absorption tank...

Abstract

The invention discloses a method for utilizing solar energy to generate power and a device thereof; the method comprises the main steps that water closed in a circulation pipeline is exposed to sunlight and runs in the circulation pipeline; the running of water in the circulation pipeline is utilized to drive a water turbine generator to generate power. The solar energy is the only driving power in the whole power generating course, therefore, no pollution is caused; the device has simple structure and low manufacturing cost, is capable of being arranged on wide sea surface, river surface or lake surface, utilizes the water in seas, rivers or lakes to cool heated water in the circulation pipeline, thereby keeping water circulating ceaselessly in the circulation pipeline and requiring no additional cooling device.

Description

technical field [0001] The present invention relates to a power generation method and device, in particular to a method and device for generating electricity using solar energy. Background technique [0002] At present, solar power generation is mainly carried out by solar panels. Solar panels are mainly based on photosensitive semiconductor materials. When the semiconductor material receives light, the holes of the N-type semiconductor in the PN junction move to the P-type region, and the electrons in the P-type region move to the N-type region, thereby forming a current from the N-type region to the P-type region, and then A potential difference is formed in the PN junction, which forms the power supply. Although solar cells have become increasingly mature in terms of manufacturing and application technologies, their manufacturing costs are several times that of traditional power generation devices, and their thermoelectric conversion efficiency is low, only about 10%. ...
