“Its configuration options, versatility, and the excellent support provided by the infinityPV team make it a strong choice for research groups working on scalable thin-film deposition.” — Askhat Jumabekov, Associate Professor
At Nazarbayev University in Kazakhstan, researchers are investigating new approaches to perovskite photovoltaic devices, with a particular focus on scalable fabrication methods and applications in tandem solar cells.
Led by Professor Askhat Jumabekov, Associate Professor in the Department of Physics, the research explores how thin-film deposition processes can be developed to produce uniform, high-quality layers while remaining compatible with larger-area manufacturing techniques.
While spin coating remains a widely used method for laboratory-scale investigations, slot-die coating offers researchers an alternative approach for studying deposition processes with relevance to scalable thin-film production. This makes it particularly interesting for the development of perovskite solar cells and advanced tandem photovoltaic architectures.
To investigate these processes under controlled laboratory conditions, the research group selected the infinityPV Research Laboratory Coater (since evolved into the Slot-die Coater).
Designed for Controlled Laboratory Environments
One of the main reasons for selecting the Slot-die Coater was its compact size and flexibility. The system can be installed inside a glovebox, allowing researchers to perform coating experiments in an inert atmosphere while limiting perovskite materials' exposure to humidity and oxygen.
Its configurable setup, including different chuck options, also allows the equipment to accommodate specific experimental requirements and substrates.
The accompanying software provides control over coating parameters and meniscus formation, supporting consistent deposition and systematic investigation of different processing conditions.
Supporting Advanced Photovoltaic Research
The infinityPV Slot-die Coater provides Nazarbayev University with a practical laboratory platform for investigating perovskite deposition methods relevant to next-generation photovoltaic devices.
Alongside the equipment's flexibility and ease of operation, Professor Jumabekov highlights the responsiveness and technical knowledge of the infinityPV support team as an important part of the experience.
The research group's experience demonstrates how compact laboratory-scale slot-die coating equipment can support the development of deposition processes for perovskite solar cells and tandem photovoltaic applications.

Full Testimonial by Professor Askhat Jumabekov
“My name is Professor Askhat Jumabekov, and I am an Associate Professor in the Physics Department at Nazarbayev University, Kazakhstan. Our research focuses on the development and fabrication of perovskite photovoltaic devices, with particular emphasis on scalable processing methods and applications in tandem solar cells. As we work toward translating laboratory-scale research into more practical and scalable fabrication approaches, having reliable coating equipment that allows us to explore different processing conditions is essential.
One of the key challenges in perovskite solar cell research is developing deposition processes that can produce uniform, high-quality films while remaining compatible with scalable manufacturing techniques. Although conventional spin coating is useful for laboratory-scale investigations, methods such as slot-die coating are particularly important for exploring larger-area devices and tandem photovoltaic applications. We therefore needed a versatile coating system that would allow us to investigate and optimize perovskite deposition under controlled and reproducible conditions.
We chose the infinityPV Slot-die Coater because of its flexibility and the range of available configurations. One feature we particularly appreciate is the ability to select different options, including the chuck, according to the requirements of our experiments and substrates. The flexibility realizes itself through the compact size of the Slot-die Coater as its dimensions allow to install it into a glovebox to perform coating in inert atmosphere. This is the core advantage for our research of perovskite photovoltaics, as it mitigates the exposure to humidity and oxygen. In doing so it provides us with a practical platform for investigating slot-die coating of perovskite materials, especially for applications relevant to tandem solar cells.
Our experience with the Slot-die Coater has been positive. We use the system for slot-die coating of perovskite layers and for exploring processing conditions relevant to our device-fabrication research. The user-friendly software that can be connected to the Slot-die Coater allows us to easily tune slot-die coating parameters, gently form the meniscus, and perform consistent coating of layers. This ability to work with a configurable coating platform supports our efforts to develop scalable deposition methodologies and investigate their suitability for more advanced photovoltaic architectures.
We have also had a very positive experience with the infinityPV support team. Their responsiveness and willingness to provide assistance have been particularly valuable in our research environment, where experimental work often requires technical guidance and adaptation to specific laboratory needs. Good equipment is important, but having a knowledgeable and supportive team behind it makes a real difference in the day-to-day research process.
Overall, the infinityPV Slot-die Coater has been a valuable tool for our perovskite photovoltaic research. Its configuration options, versatility, and the excellent support provided by the infinityPV team make it a strong choice for research groups working on scalable thin-film deposition. I would recommend the system to other academic and industrial research teams looking to develop slot-die coating processes for perovskite solar cells and tandem photovoltaic applications.”
