Abstract

The invention discloses a household micro-grid self-cleaning solar power supply system. The household micro-grid self-cleaning solar power supply system comprises a microgrid and a control system; the microgrid comprises a solar cell panel which is provided with a nano-crystalline diamond film on the surface, an inverter, a super capacitor and an electric appliance load, the inverter and the super capacitor are connected with an output end of the solar cell panel, and the electric appliance load is connected with an output end of the inverter; an output end of the super capacitor is connected with an input end of the inverter, and an input end of the electric appliance load and the output end of the inverter are connected with a normal power grid respectively; the control system comprises a single chip microcomputer, power collectors, a monitoring terminal and a data transceiving module, the single chip microcomputer is used for selecting types of power supplies which the electric appliance load accesses to, the power collectors are disposed on the electric appliance load and the solar cell panel respectively, and the data transceiving module is mounted at an output end of the single chip microcomputer. According to a preparing method for a solar cell for the household micro-grid self-cleaning solar power supply system, nano-crystalline diamond powders, ethocel and a solvent are mixed according to a mass ratio of 1: 3: (15-30) to form slurry, and the nano-crystalline diamond film is prepared on a piece of solar cell encapsulation glass by a whirl coating method to be sintered and fixed.

Description

technical field [0001] The invention relates to the application field of solar cells, in particular to a self-cleaning solar energy power supply system for household microgrids and a preparation method for solar cells thereof. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. The key component of this technology is a solar cell. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device. Micro-grid, also known as micro-grid and micro-grid, is a concept relative to traditional large power grids. It refers to a network composed of multiple distributed power sources and their related loads according to a certain topology, and is connected to the conventional power gri...

Problems solved by technology

[0003] Existing solar cells realize the collection and supply of electricity through the combination of a large number of solar cells. Due to the problems of their own efficiency and power supply, they cannot be applied in the home environment, and because solar cells are easy to attach a large amount of solar cells on the surface all year round. Dust or sundries can seriously affect its photoelectric conversion efficiency or even damage the device, making it impossible to use it in a small environment powered by a household microgrid
