We don’t venture into Austrian solar territory much, but a new project is coming together with the mild goal of revolutionizing the entire PV system. No big deal. Dubbed the Infinity project, its aim is to adapt the entire photovoltaic system, including the materials, components and processes involved, to the requirements in different climates and regions.
The project unites five scientific partners and nine leading partners in industry. The project is subsidized by the Climate and Energy Fund.
“Research and development is an important strategic factor in expanding renewable energies and achieving global climate protection goals,” says Technology minister Alois Stöger. “As effective climate policy needs innovative energy technologies, Austrian solar expertise is in demand on the global market. We therefore trust the Infinity project will continue to expand this strong position.”

The demand for photovoltaic (PV) systems has increased over the past few years, and future growth markets outside the temperate zones in particular, for example desert, (sub)tropical or alpine regions, also intend to use solar to a greater extent for generating electricity. However, there is currently only one standardized PV system for all climate zones. No options are available that can be adapted to different climate or grid conditions in specific applications.
“What we want to achieve in the Austrian lead project is to create the basis for the next generation of PV components, systems and processes. Our research is therefore into adapting both the materials and the whole PV system to different climate conditions and special regional features. In our work, we also take such factors into account as extreme temperatures, sand and instable electrical grids,” says project manager Christina Hirschl from the research center CTR Carinthian Tech Research. “If we are to achieve the energy transition, we need smart PV systems that are long lasting, energy-efficient and also affordable. The project is also aimed at improving climate protection and making companies more competitive at an international level.”
Adaptive systems deliver higher yield
The team of researchers will start off by conducting an in-depth error analysis to identify the mechanisms affecting how various materials, modules and inverters react in different climate zones both individually and as an overall system. They will then use the results gained to take a different approach to designing new, improved, climate-specific PV energy generation systems.
“A special feature of the project is the holistic research method employed along the entire PV value chain – from the PV materials and comonents to module manufacture, PV system installation and maintenance,” Hirschl says. “The scientific findings will be used to develop further process, service and maintenance strategies. Our goal is to create new energy-efficient products and also new services.”

Research is aimed at prolonging service life, reducing system costs and ultimately also yielding more electricity. Lead scientist Michael Schwark from AIT adds: “The various inputs along the value chain will significantly improve the quality of the mathematical-physical models, enabling climate-related aging predictions to be given for all parts of a PV system. Apart from optimizing the overall system, these models will also mean more accurate acceptance and maintenance recommendations for individual climate zones.”
The research work provides an important basis for developing competitive, innovative products, such as flexible materials and PV modules that can be adapted to defined climate conditions as required.
As a whole, it will give the Austrian and European photovoltaics industry the opportunity to secure a competitive edge on the global market in terms of quality and above all establish sustainable research structures with scientific experts.
