Product Introduction
P-Type mono-crystalline silicon wafers are made for top-performing solar cells and semiconductors. They're produced using the Czochralski method, giving them a consistent single-crystal structure that means great electrical properties and high conversion efficiency. By doping with boron, they get positive-type conductivity-with holes as carriers-so they're a go-to for making solar modules.
We supply P-type mono-crystalline silicon wafers, widely used in photovoltaic and semiconductor industries. With years of experience and international presence across Europe and the Americas, we aim to be your long-term partner in China.

FAQ
Q: What's the difference between P-Type and N-Type silicon wafers?
A: P-Type wafers are boron-doped and conduct via holes, whereas N-Type use phosphorus and conduct via electrons. P-Type is more commonly used in mass solar production due to lower cost.
Q: Are custom wafer sizes available?
A: Yes, we offer customization in dimensions, thickness, and surface finish based on your needs.
