Free PhD position in LPVO

August 1 2022

In the Laboratory for Photovoltaics and Optoelectronics, we have a vacancy for a young researcher in the field of integrated photonics.

In this field, in the laboratory, we deal with the design, manufacture and characterization of photonic structures and photonic integrated circuits based on silicon technologies. We are involved in the Quantera project in the field of quantum photonics for the production of efficient quantum-photonic circuits produced with the help of microtransfer printing on a silicon-nitride platform. There are many new challenges for the doctoral dissertation in this field.

The PhD student will be involved in the current research in the field of integrated photonics at the Faculty of Electrical Engineering in cooperation with leading European institutions in the aforementioned field.

Welcome to the world of integrated photonics!

Contact person: Janez Krč

Kick-off of the qTP4Q Project

June 24 2022

The Quantera uTP4Q project partners met at the kick-off meeting of the project at the University of Ghent in Belgium (June 22 2022). The Laboratory for Photovoltaics and Optoelectronics (LPVO) acts as one of six partners on behalf of the University of Ljubljana.

The project entitled A versatile quantum photonic IC platform enabled by micro-transfer printing - uTP4Q extends to the field of integrated quantum photonics. Using the micro-transfer printing method, we intend to combine different components of quantum photonics (single-photon sources, modulators, photodetectors, optical couplers and other components), which are fabricated on different photonic platforms, into a single quantum-photon integrated circuit. You can read more about the project on the web link.

Tapas project meeting

June 17 2022

After the successful completion of the EuroReg PV workshop, we hosted a meeting of the Tapas project at the Laboratory for Photovoltaics and Optoelectronics within the Faculty of Electrical Engineering. The Tapas project is a project funded by the Helmholtz European Partnership programme, which focuses on strengthening the existing cooperation between Helmholtz Zentrum Beriln and University of Ljubljana. The topic of the Tapas project is the field of tandem perovskite-silicon solar cells with an emphasis on stability research, finding the source of degradation with advanced characterization techniques, development of dedicated characterization equipment and optoelectric modelling.

Holiday Wish

December 23 2021

The year 2021 was unprecedented in many ways. Unfortunately, it was still impacted by the epidemic that changed our way of working and international cooperation. Despite the limitations, in LPVO, we will remember it for positive achievements and new experiences.

Take the advantage of the upcoming holidays to renew stocks of positive energy and efficient rest in the circle of loved ones.

In the coming year 2022, we wish you good health, effective overcoming of new challenges and sustainable personal and business development.

Happy New Year!

Kick-off of the Aurora project

December 1 2021

On December 1, we launched the AURORA (Achieving a new European Energy Awareness) project, funded by the recognized EU Horizon 2020 programme. The Aurora project is an innovation action that will bring photovoltaics closer to the citizens. We will install solar power plants with a total capacity of 1 megawatt at five locations in the EU, in Denmark, Portugal, Slovenia, Spain and the United Kingdom. Solar power plants will be crowd-funded by citizens, thus reducing their carbon footprint. With the developed app, the participants will follow their carbon footprint and, with the help of the project, reduce it as much as possible in order to become "near zero-emission citizens".

The first project meeting will be held on December 14 by the coordinator, the Polytechnic University of Madrid.
