Scientists from universities in Podkarpacie have developed a coating that extends the operation of photovoltaic panels. The project of scientists from the University of Rzeszów and the Rzeszów University of Technology received nearly 200,000 co-financing in the Podkarpackie Innovation Centre grant programme.

According to the scientific team leader Dr. Małgorzata Pociask–Biały, as part of the project, the researchers want to use a multi-layer, polymer coating with air bubbles enclosed between two layers of film with the characteristics of solar radiation micro concentrators.

'Although the thickness of this layer does not exceed 30 μm, it will be a durable coating, the transmissivity of which will correspond to a filter made of a system of air microlenses enclosed between polymers - films, during the process of their application to glass or a transparent polymer', she explains.

The result of the work of scientists from Podkarpacie is a coating that will enable longer operation of photovoltaic modules. This system can be used, for example, in terrestrial systems that produce electricity for the needs of powering electric car batteries, emergency power supply for aircraft cockpits, systems that analysing the composition of the atmosphere at different altitudes above the Earth's surface and other systems placed in space.

According to Dr. Pociask–Biały, the project will allow to easily use concentrators to amplify the short-circuit current of the cells, without embedding glass lenses into the space between the photovoltaic cells.

'Mass-produced silicon photovoltaic modules operate in the visible range, and the solution we propose improves their operating parameters, extends the scope of their use during the day and enables their adaptation by other industries', she adds.

The project received funding in the amount of PLN 200,000 in the third call for the grant programme of the Podkarpackie Innovation Centre. Work is currently underway to commercialise the project. (PAP)
