- LPVO Celebrates 20 Years
This year, the Laboratory of Photovoltaics and Optoelectronics (LPVO) celebrates the 20th anniversary of its founding. Over the past two decades, the laboratory has grown into a well-established research group in the fields of photovoltaics, optoelectronics, and photonics, and today it has more than 30 members.
By participating in numerous research projects and collaborations with both local and international partners, we have made important contributions to the advancement of knowledge and research, while also publishing a number of impactful scientific achievements. Another important part of our laboratory is education. We actively involve students through academic activities (such as seminars, bachelor’s and master’s theses), as well as extracurricular initiatives (such as student projects and the EMC Workshop). Bachelor’s, master’s and doctoral graduates from our laboratory have gone on to successful careers in both research and industry.
On this important anniversary, we express our sincere gratitude to all current and former laboratory members, students, colleagues, partners, and friends of the laboratory. Through your knowledge, dedication, and collaboration, you all play an essential role in shaping our story.
Twenty years is an important milestone, but also an inspiration for the future. We will continue to pursue our mission of advancing cutting-edge research in photovoltaics and optoelectronics, educating new generations of researchers, and through our work contributing to the development of sustainable technologies.
Thank you to everyone who has been, or continues to be, part of the successful LPVO story. We look forward to new research challenges and shared successes in the years ahead.

- The 11th Slovenian Photovoltaic Conference SLO-PV 2025
The Laboratory for Photovoltaics and Optoelectronics and the Slovenian Technological Platform for Photovoltaics are organizing the 11th Slovenian Photovoltaic Conference SLO-PV 2025, which will take place on Wednesday, 18 June 2025 at the Faculty of Electrical Engineering, Tržaška cesta 25 in Ljubljana.
At the conference, lecturers will highlight current topics in the field of photovoltaics in Slovenia. Parallel to the conference, an exhibition will be held, where companies offering products and services in the field of photovoltaics and sustainable energy will present their portfoilo. Thanks to the sponsors, participation in the conference is free of charge.
You are cordially invited! - Seminar at NREL by Prof. Marko Topič
Prof. dr. Marko Topič gave a Seminar at the National Renewable Energy Laboratory (NREL) entitled PV Materials and Devices in Energy Transition – interplay of performance, cost and stability.
In the seminar, prof. Topič first reviewed the fascinating photovoltaic (PV) technology’s modularity and continuous cost reductions that path a way solar PV to become the largest source of electricity worldwide. Although with already proven economic and environmental competitiveness, PV is successfully addressing further challenges in science, engineering and technology as well as in materials and devices to fit everywhere. Latest R&D activities in silicon and perovskite photovoltaics globally were presented with a contribution from the Laboratory for Photovoltaics and Optoelectronics (LPVO).
- Start of the ShinePV Project
In January, LPVO began participating in the international Horizon Europe project ShinePV. The ShinePV consortium includes 17 partners from 10 European countries. The project is led by the Irish and the Italian branch of Applied Materials, a corporation that supplies equipment, services and software for the production of semiconductor chips for a wide range of electronics, including solar cells.
ShinePV will develop alternative technological routes to PV production for Silicon Heterojunction (SHJ) and Tunnel Oxide Passivared Contact (TOPCon) solar cells, covering the three key steps in the back-end manufacturing: metallization, post-processing and interconnection. The goal of the project is to reinforce the sustainability of the European PV value chain building a secure, resilient, and diverse domestic energy sector industrial base.
