Due to reasons such as the simplicity of the manufacturing method and the low cost of module materials, dye-sensitized solar cells and perovskite solar cells are gaining attention. In these dye-sensitized solar cells and perovskite solar cells, the differences in the manufacturing methods of titanium dioxide thin films, which is one of the main materials for the negative electrode, significantly affect the morphology of the thin films, the electronic structure of TiO2, surface states, and consequently the light-to-energy conversion efficiency. We provide this printable TiO2 paste, other oxide pastes (including n-type and p-type semiconductors), conductive carbon for the counter electrode, carbon nanotube ink, and the perovskite precursor "Methyl Ammonium Iodide (MAI)," among others. *For more details, please refer to the PDF document or feel free to contact us. *If you would like paid samples, please inquire.

The "Carbon Alloy Catalyst (CAC)" demonstrates high oxygen reduction catalytic activity without the use of platinum, making it a platinum catalyst alternative that can contribute to reducing the cost of fuel cells. It can be utilized as an electrode catalyst for the cathodes of fuel cells and air batteries, as well as in automotive exhaust catalysts and selective oxidation catalysts for benzyl alcohol. These catalysts typically require a large amount of platinum; however, since platinum is an expensive resource concentrated in specific regions, the development of low-cost, easily procurable platinum alternative catalysts can have a significant impact on the widespread adoption of fuel cells. [Features] ■ Platinum alternative catalyst ■ Low-cost and easily procurable ■ Contributes to reducing product costs *For more details, please refer to the PDF document or feel free to contact us. *If you would like a paid sample, please inquire.
