A forward-looking idea for the solar industry
With the SWARCO Indusferica Talent Award (SITA) 2024/25, SWARCO has launched its first-ever competition to recognise innovative ideas and forward-thinking projects. SITA is aimed at emerging talent who want to rethink and advance the potential of glass bead technologies.
Increasing efficiency with reflective glass beads
Amstetten, March 2025 – The first recipient of the SITA is Cornelia Marchfelder. She presented a concept that uses reflective glass beads in base coatings to significantly increase the efficiency of bifacial photovoltaic systems. Unlike conventional solar modules, these systems generate electricity not only from direct sunlight, but also from light reflected onto the rear side – a potential that has so far remained largely untapped. Marchfelder’s approach changes that.
By incorporating glass beads with reflectance levels of up to 95%, the light yield on the rear side of the module increases considerably. This results in up to 30% higher energy output compared to conventional PV systems. In addition, the robust beads protect the coating against mechanical wear and UV radiation. In view of the growing demand for sustainable energy, this solution could play a key role in shaping the future of the solar industry.
Voices from SWARCO leadership
Thomas Auinger, Head of Indusferica, is impressed: “This submission is a strong example of how glass beads can push technological boundaries.” Peter Tomazic, Vice President Road Marking Systems Region Europe, adds: “This approach links the strengths of our products with the needs of modern solar technologies – creating real value for our customers.”
Going forward, SWARCO Indusferica aims to present the SITA annually to pioneers who contribute to the advancement of glass bead technologies through innovation. The success of Cornelia Marchfelder shows: there is tremendous potential for innovation – and SWARCO Indusferica is ready to take bold steps forward.
