High-Purity Chemicals, Solvents, Additives, Interface Materials & Consumables for Perovskite R&D and Manufacturing.
Overview
Perovskite materials are transforming next-generation solar cells, LEDs, photodetectors, displays and flexible optoelectronics. They have accelerated rapid progress from laboratory research to pre-industrial manufacturing with advantages of high power conversion efficiency, low-temperature solution processing, low cost and scalability.
Application Areas
- Perovskite Solar Cells (PSC)
- Perovskite–Silicon Tandem Cells
- Perovskite LEDs (PeLED)
- Perovskite Quantum Dots (PQDs)
- Photodetectors & Sensors
- Flexible/Wearable optoelectronics
J&K Scientific provides a wide portfolio of high-purity reagents, precursors, solvents, perovskite inks, additives, interface materials and laboratory consumables designed for both R&D laboratories and commercial manufacturing.
Our solutions aim to help customers achieve:
- Higher film quality and reproducibility
- Higher device efficiency (PCE, EQE)
- Improved photothermal and moisture stability
- Lower defect and recombination losses
- Scalable large-area film deposition

Why solvent purity matters?
√ High-purity solvents reduce:
√ Pinholes and defects
√ Crystallization inconsistency
√ Film roughness and nonuniformity
√ Hysteresis and device instability
