Novel solar cell structure fabricated by silicon nitride nanoparticles

Abstract

The invention discloses a novel solar cell structure fabricated by silicon nitride nanoparticles. The structure is fabricated by following steps: the bottom surface of a solar cell box is usually maintained to be parallel to a horizontal plane; when a weather forecast notifies the occurrence of hail, solar cells are enabled to finally approach the position vertical to the horizontal plane, and a baffle replaces the solar cell box to bear the impact of hail; after the hail is stopped, the solar cell box is returned to the state parallel to the horizontal plane, and the solar energy is receivedagain; and during rainy days, rainwater enters a water collector through a drain tank and is finally discharged through a drain pipe. According to the structure, the impact of the hail can be resistedthrough adjustment of the angle of the solar cell box, the solar cells are protected, tempered glass and an EVA material layer are cancelled, the total amount of sunlight received by solar cell panels is increased, the total amount of electric energy converted from solar energy is substantially increased, and wide application values are achieved in remote no-electricity regions.

Description

technical field [0001] The invention relates to the technical field of solar cell devices, in particular to a solar cell structure made of novel silicon nitride nanoparticles. Background technique [0002] Solar energy refers to the thermal radiation energy of the sun. It is a renewable resource with many advantages such as large amount, harmless and universal. The history of human use of solar energy can be traced back to ancient times when people used sunlight to dry items and make food. Today, people's demand for solar energy is no longer simply to use the heat of the sun. In 1615, French engineer Cox invented the world's first solar-driven engine, which opened the history of modern solar energy utilization. [0003] A solar panel refers to a device that directly or indirectly converts solar radiation energy into electrical energy through the photoelectric effect or photochemical effect. Solar panels are now mainly used in many fields such as transportation, communicat...

However, the commonly used toughened glass has a light transmittance of about 80%, coupled with the hindrance of the EVA coating, the sunlight irradiated on the solar panel is reflected by about 30%, which greatly reduces the amount of sunlight that can be transmitted by the solar panel. The total amount of sunlight utilized
