Holiday Wish

December 24 2020

The year 2020 was unprecedented in many ways. Unfortunately, it was largely 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 2021, we wish you good health, effective overcoming of new challenges and sustainable personal and business development.

Happy New Year!

Article in Journal Science

December 11 2020

An article entitledOver 29% -efficient Monolithic Perovskite / Silicon Tandem Solar Cell Enabled by Enhanced Hole Extraction was published today in the prestigious scientific journal Science. Co-authors of the article are also researchers from LPVO, namely doc. dr. Marko Jošt, dr. Gašper Matič in prof. dr. Marko Topič.

The paper discusses the fabrication and operation of a record monolithic tandem perovskite-silicon solar cell with an efficiency of 29.15%. This is a top achievement, as the cell without encapsulation retained a 95% share of the conversion efficiency after 300 hours of continuous operation, which predicts long-term stability of operation. Successful cooperation is co-financed by ARRS and Helmholtz Gemeinschaft Deutscher Forschungszentren, the latter within the bilateral TAPAS project.
