Solar Cells:
solar cells, when struck by photons of light from the sun, generates an electrical current which can then be used to power DC or AC electrical loads.
A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow
Solar cells is made by solar wafer, it has three categories of solar cell right now, monocrystalline polycrystalline and thin film,These cells are entirely based around the concept of PN junction, which is the critical part of solar module, it is the part that can convert the light energy into electricity, the thickness is from 180um to 200um, with even busbars to conduct electricity, textured cell can decrease diffuse reflection; they are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current;With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

- Q: What is the impact of solar cells on reducing dependence on foreign energy sources?
- Solar cells have a significant impact on reducing dependence on foreign energy sources as they harness the abundant and renewable energy from the sun. By generating electricity locally, solar cells help to decrease reliance on imported fossil fuels, ultimately enhancing energy security and reducing the economic and political influence of foreign energy suppliers.
- Q: How are solar cells made?
- Solar cells are typically made using a process called photovoltaic (PV) technology, which involves the assembly of semiconductor materials, usually silicon, into thin layers. The silicon is purified and then shaped into wafers, which are then treated with various dopants to create the desired electrical properties. Metal contacts are added to these wafers, and the cells are encapsulated with protective materials. When sunlight hits the cell, the photons from the sunlight create an electric field across the layers, generating electricity.
- Q: Can solar cells be used for powering remote research stations?
- Yes, solar cells can be used for powering remote research stations. Solar cells are an effective and sustainable source of renewable energy that can provide electricity in remote locations where access to the power grid is limited or nonexistent. By harnessing sunlight and converting it into electricity, solar cells can provide a reliable power supply for various research equipment and facilities in remote areas. Additionally, advancements in solar technology have made solar cells more efficient and cost-effective, making them an ideal choice for powering remote research stations.
- Q: Can solar cells be used in marine applications?
- Yes, solar cells can be used in marine applications. They can be installed on boats, ships, or other marine vessels to generate electricity from the sun.

- Q: How do solar cells perform in areas with high levels of sandstorms?
- Solar cells may not perform optimally in areas with high levels of sandstorms. The sand particles can accumulate on the surface of the solar panels, reducing their efficiency by blocking sunlight. Additionally, the abrasive nature of sand can cause damage to the panels, leading to decreased performance and potential maintenance issues. Regular cleaning and protective measures may be necessary to maintain the effectiveness of solar cells in such environments.
- Q: Solar cell life for several years
- Solar battery life of about ten years, the replacement is very convenient. Solar cells, also known as "solar chips" or "photovoltaic cells", is a direct use of solar photovoltaic power semiconductor thin film. As long as it is light to, and instantly can output voltage and in the case of a loop generated current.
