Empa researchers push boundaries with perovskite solar cells

All-perovskite tandem solar cells could soon pick up where silicon solar cells reach their limits. These highly efficient, lightweight and flexible cells have already proven themselves in the laboratory – now, Empa researchers are working on scaling them up and making them ready for the real world.

Empa researchers are developing all-perovskite tandem solar cells that could surpass the limitations of silicon solar cells. These cells have proven to be efficient, lightweight, and flexible in the laboratory.

Swiss roofs are increasingly being adorned with large black and blue rectangles that convert sunlight into electricity, with the blue color coming from silicon crystals. Silicon-based photovoltaic cells are reaching their efficiency limits, with a theoretical upper limit of 33 percent.

Empa researchers are working on scaling up perovskite solar cells for real-world applications, with projects funded by the Swiss National Science Foundation and the Swiss Federal Office of Energy. They aim to improve the efficiency and stability of perovskite cells and scale them up to industrial sizes in the next five to ten years.

Dr. Fan Fu and Dr.

Yaroslav Romanyuk from Empa are leading research on perovskite solar cells. Progress is being made in the development of these cells, which have been researched for under 15 years compared to silicon cells, which have been researched for nearly 70 years.

The researchers are optimistic about the potential of perovskite-based solar cells and anticipate industry interest in their development..
