p-type solar grade Si wafers, single or poly crystalline, large quantities available
| Product: | Silicon (Si) wafer |
| Grade: | Solar grade Solar wafers are usually polycrystalline wafers produced in industrial scale with fixed conductive type (p-type) and sizes. But we also have solar wafers of both polycrystallnity and monocrystallinity with customized sizes and resistivity for small scale non-standard applications. |
