The first autonomous photovoltaic system on a global scale with innovative graphene-perovskite frames, has been introduced with an article and a coverpage in the approved scientific journal Nature Energy – 7th issue of 2022- with a special of report on Nano@HMU research team of Prof. Emmanuel Kymakis of the Hellenic Mediterranean University.
The research team of HMU together with the team of Prof. Aldo Di Carlo of the University of Tor Vergata (Italy) and the company Bedimensional (Italy) headed by Dr. Francesco Bonaccorso worked together in the field of Energy Production of Graphene Flagship and succeeded to built the world’s first autonomous photovoltaic system using graphene-perovskiti technology along with a very low construction cost, just 40 €/m2!!
The Nano@HMU team had a key role pursuing this goal. The first author of the study, Mr. George Viskadouros together with Dr. Konstantinos Rogdakis, as well as the graduate students Ioannis Kalogerakis and Emmanuel Spiliarotis were responsible for the design of the autonomous photovoltaic system and for the construction of the special electronic equipment and software (through algorithms) required for the real-time monitoring of this new photovoltaic technology. At the same time, they carried out a comparative study and evaluation with other commercial photovoltaic technologies showing that innovative PV modules have better thermal behavior in terms of operating voltage especially at high temperatures throughout the day.
The prototype autonomous photovoltaic system, total surface 4.5m2, was installed at the “OpenAir Lab” at HMU campus, while its operation was monitoring for more than 12 months. During the experimental period Cretan researchers were able to extract valuable information in real operating conditions. Based on the experimental results, a Life Cycle Assessment Study was produced, an important step towards the complete industrialization of technology.
Another impressive element of the experiment is that the autonomous solar park achieved a remarkable stable energy production while maintaining 80% of the original power output for 5,832 hours (8 months)!!
The stability of the GRAPE PV modules is the best performance of perovskite technology worldwide.The research paper can be found at the following link: https://lnkd.in/euTMKD3Z
