Best poster award at ECIO23
April 22 2023
At the 24. European Conference on Integrated Optics the member of Laboratory for Photovoltaics and Optoelectronics as. dr. Andraž Debevc recieved the third prize for the best poster at the conference along with coatuthors of the contribution prof. dr. Marko Topič and prof. dr. Janez Krč. The comitee awarded 3 best posters out of a total of 46 posters that were presented at the conference.

Article in Journal Science
April 7 2023
The prestigious scientific journal Science published the article Photovoltaics at multi-terawatt scale: Waiting is not an option, which was signed by the most prominent American, Asian and European experts in the field of photovoltaics, including Prof. dr. Marko Topič from the Laboratory for Photovoltaics and Optoelectronics together with five colleagues of the European Technology and Innovation Platform (ETIP PV), to which Prof. Topič presided until recently.
The article talks about the important contribution of photovoltaics to the transformation of energy, which was prepared by the aforementioned experts after the third international Terawatt Workshop. The article substantiates the reasons for the exponential growth of photovoltaics, which exceeded the total power of 1000 GW of solar power plants by 2022 and, based on current research and innovation, projects that in the next decade we will maintain a 25% annual global growth of photovoltaics and reach 75 TW of installed solar power by 2050 power plant. Given the climate crisis, hesitation is out of the question. At this rate, photovoltaics will play a key role in limiting climate change and in the transition to sustainable energy. Not only in the field of electricity production, but also with the electrification of other energy sectors and the production of solar fuels with hydrogen at the forefront.
December 23 2022
The year 2022 was exceptional for photovoltaics in Slovenia, as the current estimate of newly connected solar PV power plants exceeds 250 MW. This is a 50% increase in the cumulative installed PV power, which mostly comes from private investments in small solar PV power plants in net-metering scheme.
The year 2022 was also exceptional for the Laboratory for Photovoltaics and Optoelectronics. We will remember it for the excellent achievements of its members:
- Prof. Em. Dr. Franc Smole – elected as a Professor Emeritus of University of Ljubljana
- Prof. Dr. Marko Topič – Becquerel Award for outstanding merits in Photovoltaics
- Assoc. Prof. Dr. Marko Jankovec – Vidmar's Award
- Asst. Prof. Dr. Marko Jošt et al. – Recognition for one of the top 10 research achievements of the University of Ljubljana in 2022
At the end of the year, we wish you to take the advantage of relaxing holidays for an effective rest, which will ensure the renewal of positive energy and prepare you for a healthy, successful and happy coming year 2023!
Happy New Year!
