Scientists from the École Polytechnique Fédérale de Lausanne in Switzerland have recently developed low-cost perovskite solar panels that have 11.2 percent power-conversion efficiency and capable of operating for more than a year, without loss in performance.

The solar panel, described in a paper published in the journal Nature Communications, is a combination of 2D and 3D perovskite solar cell. Perovskite cells can mimic the structure of calcium titanate (CaTiO3) crystals. However, these kinds of solar cells have a range of light-capturing capacities depending on its elements.

Perovskite solar cells do not need any substantial quantities of expensive materials nor high-temperature processes, making it extremely cheap to produce. With over 22 percent power-conversion efficiency, perovskite cells have great potential for commercialization. However, there…
