Small Solar Desk Cooling Fan

Product principle1. Solar energy conversion: Small Solar Desk Cooling Fan is equipped with a sophisticated solar panel, which is its core energy source component. Solar panels are composed of multiple photovoltaic cells, which work on the principle of photoelectric effect. When sunlight shines on the solar panel, photons hit the semiconductor material in the photovoltaic cell, causing the electrons in the material to gain energy and break free from the atomic bondage, thereby generating electron-hole pairs. Under the action of the electric field inside the battery, the electrons and holes move in opposite directions, forming a current, converting solar energy into electrical energy.   2. Electric energy storage and use: Part of the converted electrical energy directly powers the fan motor to drive the motor to operate. The motor drives the fan blades to rotate at high speed through the transmission device. The special shape and angle design of the fan blades enable the surrounding…
