    AI Overview
    Non-metallized PERC (Passivated Emitter and Rear Contact) solar wafers are high-efficiency monocrystalline p-type silicon substrates, typically 182mm or 210mm in size, that feature a passivation layer (usually
    Al2
    O3
     and
    SiNxSiN sub x
    SiN𝑥
    ) on the rear but lack screen-printed metallic contacts. These textured, clean wafers are designed for subsequent laser processing and metallization to achieve >20% efficiency. 
    Key Aspects of Non-Metallized PERC Wafers 
    • Structure: These wafers have a textured surface for improved light absorption and a rear passivation layer that reduces recombination losses, enhancing overall efficiency.
    • Material: Primarily monocrystalline p-type Czochralski (Cz) silicon wafers are used, often Gallium-doped to improve stability against light-induced degradation (LeTID).
    • Process Stage: These represent a mid-process state, usually textured, diffused, and passivated, but require laser doping or laser firing and silver/aluminum paste printing to become finished cells.
    • Advantage: Purchasing non-metallized PERC wafers allows for specialized or improved, custom screen-printing and firing-through processes to form local electrical contacts, allowing for customized performance. 
    These wafers are commonly used to produce standard PERC cells and can also be utilized for bifacial PERC modules, which generate power from both sides.

    What is the difference between solar cells and wafers?
    Solar cells prioritize cost and efficiency, so lower purity silicon, polycrystalline structures, and textured surfaces are often used. Semiconductor wafers are reused or reclaimed, whereas solar wafers are permanently embedded into panels.

    What non metal is used in solar cells?
    A typical solar panel comprises a glass enclosure, a metal frame, a layer of silicon cells, and different wiring to let current pass from the silicon cells. A non-metal with conductive qualities, silicon can gather sunlight and turn it into electricity.

    Which is better, mono perc or TOPCon?
    How much higher is TOPCon efficiency compared to mono PERC solar panels? TOPCon panels are typically 1–2% more efficient than Mono PERC, with commercial efficiencies around 22–24% versus 19–22%. This difference significantly increases power output, especially in space-constrained installations.Apr 15, 2026
