Article in Journal Science

December 11, 2020

An article entitled Over 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.
