What is photovoltaic

Photovoltaics is a technology that converts light energy into electrical energy, generating free electrons and forming electric current through the photovoltaic effect. Photovoltaic systems include solar panels, inverters and controllers and are widely used in photovoltaic power generation, power supply systems, electronic equipment power supply and space exploration. Its advantages include cleanliness, non-pollution, strong renewable nature, distributed power generation and low maintenance costs.

What is photovoltaic?

Photovoltaic is a technology that converts light energy directly into electrical energy through solar cells. A solar cell is a semiconductor device that generates electricity when photons strike its surface.

The working principle of photovoltaics:

The basic working principle of solar cells is the photovoltaic effect. When photons strike a solar cell, the energy in the photons is absorbed by electrons in the semiconductor material. The absorbed energy causes electrons to excite and leave their nuclei, creating free electrons. These free electrons move within the solar cell, producing an electric current.

Composition of photovoltaic system:

Photovoltaic system usually includes the following components:

• Solar panels:By It is composed of multiple solar cells and is responsible for converting light energy into electrical energy.
• Inverter: Converts the DC power generated by solar cells into AC power for connection to the power grid or electrical appliances.
• Controller: Regulate and monitor the work of the system.

Applications of photovoltaics:

Photovoltaic technology is widely used in various fields, including:

• Photovoltaic power generation : Generate clean, renewable electricity.
• Photovoltaic power supply system: Provide power for remote areas or off-grid applications.
• Solar panels: Power electronic devices, vehicles and homes.
• Special applications: Such as space exploration, buoy power supply, etc.

Advantages of photovoltaics:

• Clean energy: Photovoltaics do not produce greenhouse gases or other pollutants.
• Renewable energy: Solar energy is an inexhaustible resource.
• Distributed power generation: Photovoltaic systems can be installed on rooftops, parking lots and open spaces to achieve distributed power generation.
• Low maintenance cost: Solar panels have long life and low maintenance cost.
