Solar photovoltaic technology converts light into electricity at the atomic level. The photoelectric effect causes certain semiconductor materials to absorb sunlight particles, or photons, and release electrons. Photovoltaic cells use visible light to generate electricity; solar cells absorb all light frequencies in sunlight, not just visible light, and convert solar radiation into useful energy. As a safe, sustainable and efficient energy source, photovoltaic and solar cell systems can be used for network or stand-alone generation in many types of equipment, from solar rooftops to water pumping and desalination systems.

Photovoltaic cells use layered semiconductor materials as PN junctions to convert light energy in the form of photons into current in the form of electrons. The PN junction is the interface between p-type semiconductor (electron acceptor material) and n-type semiconductor (electron donor material). When photons are absorbed by an n-type semiconductor, electrons are expelled, creating free electrons and electron-hole pairs. Negatively charged electrons are attracted to p-type materials, and positively charged holes are attracted to n-type materials. If a complete circuit is connected to an electrode, the free electron will travel through the circuit, producing current and voltage, until it recombines with the electron hole back into the p-type material.

Solar cells are a green, environmentally friendly energy source that can directly convert sunlight into electrical energy. You should pay attention to the following points when purchasing solar cells:

1. Parameters such as required power and voltage need to be considered.

2. Choose high-efficiency solar cells as much as possible to improve power generation efficiency.

3. Understand the climate environment you are in and the sunshine conditions of the installation site to determine how many solar panels are needed to meet your needs.

You should also pay attention to the following things when choosing solar cells:

1. Choose a solar cell mounting bracket that is waterproof, sun-proof, and wind-resistant.

2. Understand the support of national and local policies for solar cell subsidies, installation and use.

3. Factors such as repair costs and maintenance cycles should be considered when selecting solar cells.

GEM Battery solar cells are a clean energy technology. GEM Battery solar cells convert sunlight directly into electricity without producing pollutants or greenhouse gas emissions. They are a form of renewable energy because sunlight is a constantly available and widely available resource.
