Novel Additive Helps Improve Stability of Perovskite/Silicon Tandem Solar Cells

Perovskite/silicon tandem solar cells have the potential to revolutionize the solar industry by achieving high efficiency and low cost. However, the stability of these cells has been a major challenge, as perovskite materials are prone to degradation under environmental conditions.

Researchers at the University of California, Los Angeles (UCLA) have developed a novel additive that can improve the stability of perovskite/silicon tandem solar cells. The additive is a small organic molecule that can be easily incorporated into the perovskite layer during the fabrication process.

The researchers tested the stability of the cells under various environmental conditions, including high temperature, humidity, and light exposure. They found that the cells with the additive showed significantly improved stability compared to those without the additive.

The mechanism behind the improved stability is still under investigation, but the researchers believe that the additive helps to passivate defects in the perovskite layer and prevent moisture and oxygen from penetrating the layer.

This breakthrough could pave the way for the commercialization of perovskite/silicon tandem solar cells, which have the potential to achieve efficiencies of over 30% and significantly reduce the cost of solar energy.

Further research is needed to optimize the additive and improve the efficiency and stability of perovskite/silicon tandem solar cells. However, this development is a promising step towards a sustainable and affordable energy future.
