A forward-looking idea for the solar industry
The SWARCO Indusferica Talent Award (SITA) 2024/25 marks the launch of a new competition designed to recognize innovative ideas and pioneering projects. SITA is aimed at emerging talent seeking to rethink and advance the diverse applications of glass beads.
Increasing efficiency with reflective glass beads
Amstetten, March 2025 – The first recipient of the SITA 2024/25 award is Cornelia Marchfelder, who presented a concept focused on the targeted use of reflective glass beads in sublayer coatings to significantly increase the efficiency of bifacial photovoltaic systems. These modules not only generate energy from direct sunlight but also from light reflected onto the back of the module – a previously untapped potential that Marchfelder now brings into play.
By integrating glass beads capable of reflecting up to 95% of light, the rear-side energy yield is maximized. This could lead to up to 30% higher output compared to conventional PV modules. At the same time, the durable beads protect the coatings from mechanical wear and UV radiation. In a time where sustainable energy is more important than ever, this approach could help shape the future of the solar industry.
Voices from SWARCO leadership
Thomas Auinger, Head of Indusferica, was impressed: "This submission is a remarkable example of how glass beads can push boundaries and enable innovative solutions for sustainable technologies." Peter Tomazic, Vice President Road Marking Systems Region Europe, also underlined the idea’s relevance: "The concept combines the strengths of our glass beads with the demands of modern solar technology, creating real added value for our customers."
Through the SITA Award, SWARCO Indusferica aims to annually honor pioneers and creative minds who contribute to the development of new glass bead technologies. Cornelia Marchfelder’s success demonstrates just how much innovation potential lies in this field – and that SWARCO Indusferica is ready to break new ground.
