Polycrystalline Silicon Solar Cells:
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 ap-n 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.

- Yes, solar cells can be used in swimming pool heating. Solar panels can capture sunlight and convert it into energy, which can then be used to heat the pool water. This renewable energy source is environmentally friendly and can help reduce energy costs associated with pool heating.
- Q: Can solar cells be used for desalination purposes?
- Yes, solar cells can be used for desalination purposes. Solar-powered desalination systems, such as solar stills and solar desalination plants, harness the energy from the sun to power the desalination process. This renewable energy source helps reduce the environmental impact of desalination and promotes sustainable water production.
- Q: Is the solar cells factory in China good and trustworthy?
- As long as it's real factories which have passed related quality assurance tests with the authentic certificatse for producing the solar cells, they are good.
- Q: How do solar cells affect the environment?
- Solar cells have a positive impact on the environment. They produce clean, renewable energy by converting sunlight into electricity, reducing the reliance on fossil fuels. Solar cells emit no greenhouse gases or air pollutants during operation, helping to combat climate change and improve air quality.
