Thin, Lightweight Layer Provides Radiation Barrier for Perovskites in Space, Protection from Elements on Earth

Introduction

Perovskites are a class of materials that have been gaining popularity in the field of solar energy due to their high efficiency and low cost. However, perovskites are also known to be sensitive to radiation, which can degrade their performance over time. In order to address this issue, researchers have developed a thin, lightweight layer that can provide a radiation barrier for perovskites in space, as well as protection from the elements on Earth.

What are Perovskites?

Perovskites are a class of materials that have a unique crystal structure, named after the mineral perovskite. They have been found to be highly efficient in converting sunlight into electricity, making them a promising candidate for use in solar cells. Perovskites are also relatively cheap to produce, which makes them an attractive alternative to traditional silicon-based solar cells.

The Problem with Radiation

One of the challenges with using perovskites in space is that they are sensitive to radiation. Radiation can cause defects in the crystal structure of the perovskite, which can degrade its performance over time. This is a particular concern for space applications, where the level of radiation is much higher than on Earth.

The Solution: A Thin, Lightweight Layer

To address this issue, researchers at the University of Cambridge have developed a thin, lightweight layer that can provide a radiation barrier for perovskites in space. The layer is made from a material called hafnium oxide, which has been shown to be effective at blocking radiation.

The hafnium oxide layer is only a few nanometers thick, which means that it does not add significant weight or bulk to the perovskite solar cell. This is important for space applications, where weight and size are critical factors.

Protection from the Elements on Earth

In addition to providing a radiation barrier in space, the hafnium oxide layer also provides protection from the elements on Earth. Perovskites are known to be sensitive to moisture and oxygen, which can degrade their performance over time. The hafnium oxide layer acts as a barrier, preventing moisture and oxygen from reaching the perovskite.

Conclusion

Perovskites have the potential to revolutionize the field of solar energy, but their sensitivity to radiation has been a major obstacle to their widespread use. The development of a thin, lightweight layer that can provide a radiation barrier for perovskites in space, as well as protection from the elements on Earth, is a significant breakthrough that could pave the way for the widespread adoption of perovskite solar cells.
