In summer, power shortages often occur, and solar fans generate electricity by utilizing natural resources—sunlight. The working principle of a solar fan is that a solar panel converts light into voltage as soon as it receives sunlight. This voltage is then transmitted via cables to the fan’s motor, which drives the fan through gear transmission. Do all kids need a small fan during summer? However, fans require batteries, and batteries consume energy very quickly. So let’s create a solar-powered fan. Let’s take a look at the manufacturing steps!
Experiment focus: Understanding the basic configuration principle of a shampoo-powered fan.
Experimental objectives: 1. To understand the main components of solar fans
2. Understand the role of each component in the solar fan
Experimental Cognition:
Solar panels: Solar cells (Solar panel) are devices that directly or indirectly convert solar radiation into electrical energy through photoelectric or photochemical effects by absorbing sunlight. The main material used in most solar cells is "silicon," but due to high production costs, they have not yet been widely used. Compared to conventional batteries and rechargeable batteries, solar cells are more energy-efficient and environmentally friendly green products.
Solar motor: A solar motor includes solar cells and is designed based on a concept that can generate power using sunlight. This motor converts thermal energy into electrical energy through solar panels, allowing for highly efficient and cost-effective power generation.
Knowledge Expansion: When sunlight hits the p-n junction of a semiconductor, new hole-electron pairs are formed. Under the influence of the p-n junction electric field, holes flow from the n region to the p region, and electrons flow from the p region to the n region. Once a circuit is established, an electric current is generated. This is how the principle of photoelectric solar cells works.
