KTU Researchers Overcome Major Drawback of Perovskite Solar Cells

Breakthrough in stability and efficiency paves way for widespread adoption of renewable energy source

Dr. Kasparas Rakšty, a researcher at Kaunas University of Technology (KTU), has faced the challenge of insufficient long-term stability of perovskite solar cells, which has hindered their commercial adoption, despite their great promise as a renewable energy source, in the context of global electricity consumption continuing to rise, with demand projected to surge by 2030, as of August 13, 2026.

Perovskite solar cells have shown great promise as a renewable energy source, but their commercial adoption has been hindered by a major drawback: insufficient long-term stability when exposed to moisture, heat, and oxygen. A team of researchers at KTU, led by Dr. Rakšty, has made a significant breakthrough in addressing this challenge.

The team has created a more stable interface between the different layers of the solar cell, enabling the device to operate more efficiently and maintain its performance for longer. This breakthrough has the potential to pave the way for the widespread adoption of perovskite solar cells as a renewable energy source.

Dr. Rakšty was direct: "a solar cell can be imagined as a multi-layered sandwich in which each layer is made of a different material and performs a specific function." The team's research has focused on improving the stability of the interface between these layers, which is critical to the overall performance of the solar cell.
