KOREA KIYON will participate in IPEROP26 with a technical booth and a 5-minute industry pitch, presenting integrated equipment solutions that bridge laboratory-scale perovskite and organic photovoltaic research with scalable manufacturing processes. While remarkable efficiencies are routinely demonstrated at the laboratory level, a persistent challenge remains in translating these results into reproducible, high-yield production. In most cases, the limitation is not material performance itself, but the difficulty of maintaining strict environmental control across wet chemistry, thin-film deposition, and interface formation.

Variability arising from oxygen and moisture exposure, residual solvents, and handling inconsistencies often dominates device-to-device performance dispersion, masking true optimization pathways. KIYON addresses these challenges by providing tightly controlled processing environments that enable stable, repeatable workflows from early research to pilot-scale manufacturing.

For solution-processed photoactive layers, KIYON offers gloveboxes and enclosed processing platforms that maintain oxygen and moisture levels below 1 ppm. These systems support stable precursor preparation, coating, and annealing for perovskite and organic semiconductor materials. Within these inert environments, scale-oriented deposition methods such as slot-die and inkjet coating can be implemented, enabling uniform large-area film formation with higher throughput compared to spin-coating. As a result, KIYON’s wet-process platforms function as a practical bridge between exploratory material development and manufacturing-relevant workflows, while preserving the atmospheric control essential for high-quality crystallization and defect management.

To further enhance process control and operational safety, KIYON provides optional instrumentation including real-time oxygen and moisture analyzers, as well as solvent trap systems for effective management of organic solvents during extended coating runs. These modules become increasingly critical at scale, where consistent atmospheric metrics and standardized operating procedures (SOPs) are essential for multi-batch reproducibility.

For dry processing and hybrid device architectures, KIYON’s vacuum tool portfolio includes thermal evaporation, sputtering, e-beam evaporation, and atomic layer deposition (ALD) systems. These platforms support the deposition of charge transport layers, passivation layers, electrodes, and transparent conductive oxides. In particular, KIYON’s sputtering systems enable co-sputtering and flexible switching between RF and DC power sources, allowing precise tuning of film composition, crystallinity, adhesion, and interfacial properties—key parameters governing efficiency and long-term stability in perovskite and organic photovoltaics.

A key highlight of KIYON’s portfolio is the Perovskite Tandem Double Cluster System (KK-CU/GB-210-TSC), designed for large-area G12 substrates (210 × 210 mm). This platform integrates a perovskite cluster tool optimized for wavelengths below 850 nm with a CIGS cluster tool covering the 800–1100 nm absorption range, enabling complete processing of CIGS–perovskite tandem devices. The double-cluster, double load-lock configuration maximizes productivity through full automation and independent chamber control. In addition, a dedicated selenium trap in the CIGS chamber prevents cross-contamination of neighboring chambers and vacuum pumps, addressing a critical reliability challenge in multi-material tandem manufacturing.

At IPEROP26, KIYON will present end-to-end process concepts that connect inert wet coating, advanced vacuum deposition, and tandem integration into scalable manufacturing methodologies. We welcome discussions with researchers and industry partners on turnkey production lines, system customization for specific materials and device architectures, and collaborative development opportunities.
