Solar Panel

Background
A photovoltaic cell, also called a solar cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. In fact, it is a semiconductor photo diode, and when exposed to sunlight, solar energy is changed into electricity and an electric current is generated. An assembly of such photovoltaic cells could be connected together to form a photovoltaic module, but this module is not able to work as a power supply because a single solar module can produce only a limited amount of power.

Given this, people developed solar panel which is a set of solar photovoltaic modules that are connected in series or parallel, strictly packaged and mounted on a supporting structure, and it is the core part for a solar power system.

At present, crystalline silicon, including monocrystalline type and polycrystalline type, is the most important photovoltaic material, taking up a market share of over 90%. The polycrystalline silicon is mainly used in semiconductors and solar cells, and the solar photovoltaic industry will exceed nuclear power and become one of the most fundamental energy sources at the first half of the 21st century.

Applications
The solar panel is such a universal device that it could be seen in almost every field, such as transportation, communication, satellite, spacecraft, petroleum industry, household lamp, solar building, solar vehicle, solar energy system, battery charging device, photovoltaic power station, solar energy space station, etc.

Compositions and Functions
1. Tempered glass: It is used to protect the solar cell.
2. EVA: It bonds solar cell and tempered glass firmly.
3. Solar cell: It is the core part for power generation, and the commonly seen types on the market are crystalline silicon type and thin film type.
4. Back plate: It is applied for the purposes of sealing, insulation and water resistance.
5. Aluminum alloy: It protects solar laminates, and it is also capable of sealing and supporting to some extent.
6. Junction box: It offers protections for the entire power generating system, and it works as a "current transfer station".
7. Silicone sealant: It is adopted to seal the boundary between solar panel and aluminum alloy frame as well as the boundary between solar panel and junction box.
