TiO₂ Nanoparticles for Solar Cell
As the world pivots toward clean energy, solar power stands at the forefront. But to improve the efficiency, durability, and cost-effectiveness of solar cells, advanced nanomaterials are critical.
Titanium Dioxide (TiO₂) nanoparticles have emerged as one of the most reliable and versatile materials for photovoltaic applications. Their exceptional electronic properties, wide bandgap, and high chemical stability make them ideal for use in dye-sensitized solar cells (DSSCs), perovskite solar cells, and photocatalytic devices.
At Schnaiffer, we synthesize high-purity TiO₂ nanoparticles optimized for solar cell fabrication, R&D, and prototyping across academic and industrial labs.
Why TiO₂ Nanoparticles for Solar Cells ?
- Efficient Electron Transport: Facilitates charge separation and mobility
- Scattering Layer Role: Enhances light absorption in multi-layer devices
- Photostability: Supports long-term device durability
- Low-Cost and Abundant: Ideal for scaling up production
- Eco-Friendly: Non-toxic and environmentally safe material
Applications
- Dye-Sensitized Solar Cells (DSSCs)
- Perovskite Solar Cells (as electron transport layer)
- Quantum Dot Solar Cells
- Photocatalytic Hydrogen Production Panels
- Transparent Solar Panels (TiO₂ in mesoporous layer)
Our Fabrication Process
At Schnaiffer, we produce TiO₂ nanoparticles using a sol-gel synthesis route, followed by thermal treatment for phase control and particle size tuning.
