Silicon Nanoantennas Enhance Perovskite Solar Cells Efficiency

• Revolutionary method using silicon nanoantennas boosts efficiency of perovskite solar cells, paving the way for indoor lighting and space industry applications.

Researchers from Harbin Engineering University, ITMO University, and Hellenic Mediterranean University have developed a method using silicon nanoantennas to enhance perovskite solar cells. By increasing the concentration of light in the material at specific wavelengths, the team was able to improve the efficiency of the solar cells. This advancement could potentially lead to the creation of solar cells for indoor lighting and even for use in the space industry.

Perovskite solar cells are lightweight, thin, and easy to produce, making them a promising option for solar energy generation. However, like other semiconductors, perovskites absorb only a fraction of the spectrum, resulting in lower energy generation. The use of silicon-based optical resonant nanoantennas in perovskite solar cells has shown promising results in increasing efficiency, with some samples achieving up to a 20.5% conversion rate. Further research will focus on expanding the range of applications for these improved solar cells, potentially including underwater and space environments.
