Scientific activity

The institute's scientific developments are part of the driving force of global technological progress

Each of our developments is based on deep scientific research. Instead of following popular trends, we focus on solving fundamental scientific problems in key areas of applied physics and electronics. Our scientific activities are focused on creating technologies that can operate in extreme conditions - from space vacuum and radiation to ultra-high temperatures and energy concentrations. This approach creates a unique margin of safety, which opens up new horizons of application for our developments, far beyond their original purpose.

Main areas of scientific research:

High-energy physics

Development of unique radiation-resistant electronics for particle detectors. We are partners with leading world science centers such as CERN (Switzerland) and participate in landmark international experiments, including projects at the Large Hadron Collider

Concentrated solar power

Creation of highly efficient photovoltaic systems capable of operating in conditions of ultra-high concentration of sunlight. We develop both unique solar cells and ready-made modules that efficiently convert the energy of highly concentrated radiation

Solar energy in space

Design and manufacture of highly efficient and reliable solar panels for spacecraft. Our designs withstand the harsh conditions of space, such as deep vacuum, radiation, and extreme temperature changes

Science-intensive lighting technology

Development of intelligent power supply and control systems for LED equipment. Our scientific approach is focused on creating reliable and energy-efficient lighting complexes to solve a wide variety of tasks

High-energy physics

Development of unique detector systems for experiments in fundamental science

High-energy physics is a branch of fundamental science that studies elementary particles and their interactions, recreating the conditions that existed in the first moments of the Universe. Research in this area is carried out at complex experimental facilities, such as the Large Hadron Collider (CERN) and the future FAIR accelerator complex.

However, to record and analyze the results of these experiments, specialized high-precision measuring complexes - detector systems are required. It is precisely in the development and creation of unique radiation-resistant microelectronics, which performs the main measuring function in such systems, that our institute specializes. We create high-precision components that are able to operate in extreme conditions, recording data that form the basis of future scientific discoveries.

Examples of developments

High-precision technological solutions that meet the highest requirements of experimental physics

One of the main advantages of the SRITAS is the ability to control the entire development cycle, starting from the most important stage - the creation of our own unique materials. They become the basis for all our subsequent high-precision components, which allows us to achieve record performance and flexibility in solving problems.

Unique aluminum-polyimide materials
For the first time in Ukraine, we have developed and implemented a technology for manufacturing our own adhesive-free layered materials for flexible printed circuit boards. Our patented technology allows us to create materials that are significantly cheaper than global counterparts and are capable of operating in an extreme temperature range (from -200°C to +250°C).
Flexible multilayer cables and boards
Based on our own materials, we create ultra-thin and flexible multilayer power cables and connecting loops. Their innovative design provides increased radiation resistance, minimal weight, eliminates corrosion and significantly simplifies installation in complex detector systems.
Multi-sensor detector modules
Our patented technology for creating modules on flexible circuit boards allows us to achieve exceptional characteristics - minimal impact on the particle trajectory (radiation length up to 0.1-0.2 %X₀), high spatial resolution (up to 5-10 μm) and a significant reduction in sensor noise. Using ultra-modern thin silicon sensors, our modules allow us to obtain the most accurate indicators in physical experiments.

Prospects

Our priorities are constant development and the search for new horizons for the application of our developments

Our work in the field of high-energy physics is not limited to already implemented projects. We work within the framework of long-term framework agreements (for 3-5 years) with our international partners, which involves the constant improvement of existing developments and the creation of new solutions for future experiments.

In addition, the experience gained in creating electronics for extreme conditions is an invaluable asset of the institute and our specialists. Technological approaches and solutions tested in radiation and critical temperature conditions find their direct application in other science-intensive areas, in particular in the aerospace industry and precision industrial instrument-making.

Our main contribution, regardless of the field of application, is the creation of reliable tools that allow obtaining accurate data in the most difficult conditions. We create technologies that enable both ambitious scientific research and complex engineering projects, expanding the boundaries of human knowledge and capabilities and accelerating technological progress.

Concentrating Solar Power

Efficiency multiplied by a thousand - developing solutions for concentrator photovoltaics

A standard solar panel has physical efficiency limitations. To overcome them, there is a more complex and science-intensive approach - concentrator photovoltaics (CPV). Its essence lies in focusing sunlight using lenses or mirrors onto a very small, but extremely efficient solar cell. This allows you to get much more energy from a smaller area, but creates huge technological challenges, including the need for effective heat dissipation and the development of unique materials.

It is on solving these problems that our developments are focused. We create a key functional unit of such systems - high-tech solar receivers, capable of withstanding ultra-high light concentrations and efficiently converting it into electricity. Our solutions are based on advanced gallium arsenide solar cells and our own innovative collection technologies.

Key developments

From innovative materials to finished solar receivers certified according to world standards

Our work in this area covers the entire product development cycle, which is confirmed by participation in international research programs, such as the APOLLON project (FP-7 EU). Our key developments include:

High-efficiency solar receivers
A number of receiver designs have been created based on the world's best triple-junction gallium arsenide solar cells (efficiency 36-38%). Our unique aluminum-polyimide Chip-On-Flex (COF) assembly technology ensures the reliability and durability of the entire system.
Advanced optical solutions
Comprehensive research and development of secondary optical elements (SOE) have been carried out, which allow for the most efficient use of focused light. In addition, we have proposed an innovative approach using achromatic Fresnel lenses, which simplifies and reduces the cost of the module design without losing efficiency.
Reliability testing and certification
Our developments have undergone a full cycle of accelerated thermal cycling tests for reliability and durability. The results confirmed the full compliance of our solar receivers with the strict international standard IEC 62108. The expected service life of our products is at least 20 years.

Key developments

Prospects

The goal of our institute is to make concentrator photovoltaics commercially effective

We do not stop there and continue to improve our technologies. Our main priority is to achieve the optimal combination of maximum efficiency and commercial attractiveness of concentrator solar energy.

Our new developments are aimed at using solar cells with an efficiency of over 46%, which will allow creating concentrator modules with a final efficiency of more than 40% at a concentration degree of over 500 times. This will potentially allow achieving a competitive cost of generated electricity at the level of 0.2-0.5 Euro per W, which meets the highest global requirements and paves the way for the widespread implementation of this technology.
