What Substrates Are Used In Photovoltaic Research

In photovoltaic research, several substrates are used depending on the type of solar cell technology being developed. Here are some common substrates used in photovoltaic research:

  1. Silicon Wafers:

  2. Thin-Film Substrates:

    • Glass: Commonly used for cadmium telluride (CdTe) and amorphous silicon (a-Si) solar cells.
    • Metal Foils: Such as stainless steel, used for copper indium gallium selenide (CIGS) solar cells.
    • Plastic Films: Lightweight and flexible substrates for organic photovoltaic (OPV) and perovskite solar cells.

  3. Perovskite Substrates:

    • Glass with Transparent Conductive Oxides (TCOs): Such as indium tin oxide (ITO) or fluorine-doped tin oxide (FTO), used in combination with perovskite materials.
    • Flexible Polymers: For lightweight and flexible perovskite solar cells.

  4. Organic Substrates:

    • Plastic Films: Such as polyethylene terephthalate (PET) or polyethylene naphthalate (PEN), used for organic photovoltaic (OPV) cells.
    • Paper: For experimental low-cost and biodegradable solar cells.

  5. Emerging Materials:

    • 2D Materials: Such as graphene, used for novel photovoltaic applications.
    • Hybrid Materials: Combining organic and inorganic materials for improved performance.

These substrates are chosen based on their mechanical properties, compatibility with the photovoltaic materials, and the intended application of the solar cells (e.g., rigid vs. flexible, high-efficiency vs. low-cost).
