Perovskite Quantum Dots Supplier - Alfa Chemistry

Stability Adjustment


As a company focused on providing quantum dot services, Alfa Chemistry has all the necessary resources to provide process development, optimization and mass production, and R&D personnel are involved in the process of each procedure to provide customers with high-quality products more efficiently Quantum dots and product solutions.


In the field of quantum dot solar cells, PbS quantum dots are generally used as the active layer because of its better stability in the air. PbSe quantum dots have a stronger quantum confinement effect and a more efficient multi-exciton generation effect than PbS quantum dots in the battery, and the external quantum efficiency exceeds 100%, up to 114%, so it is more important in solar cells. Has application potential. However, since PbSe quantum dots are very sensitive to air, it is very important to enhance their stability.


Alfa Chemistry can provide customers with PbSe quantum dot stabilization services. With reference to the existing quantum dot technology and the current cutting-edge methods, we can customize the stabilized quantum dots and also provide stable performance services for customers' quantum dots.
