Perovskite Material to Replace Silicon in the Near Future

Silicon has been dominating the electronics and solar energy industry for years. The reason behind this is not because it is the most efficient element but it is the only available element that has the desired stability to be utilized in commercial sectors.

However, several researchers are finding other elements than could probably replace silicon on grounds of cost-effectiveness, physical, and chemical properties and cost parameters.

In this wake, various scientists at the international research collaboration, Shanghai Jiao Tong University, the Okinawa Institute of Science and Technology Graduate University (OIST), and EcolePolytechniqueFédérale de Lausanne (EPFL) collaborated to find a material that is equally efficient as that of silicon.

Perovskite Material Has High Energy Stability

According to them, perovskite material could replace silicon in semiconductors and other industries. Previously, researchers have studied CsPbI3 in the alpha phase, but this time the researchers studied its properties in beta phase. The found that perovskite has higher energy stability in its alpha phase. In addition to this, the structure is more stable and has low power conversion efficiency as compared to other phases.

The scientist figured out a substantial way to deal with the low power conversion efficiency of perovskite. They treated the element with a choline iodide solution that helps in controlling electron loss by healing the cracks. The process of healing the cracks in the perovskite element is termed as energy level alignment.

With the simple processing, CsPbI3 into could offer tough completion to rival silicon solar materials in the coming years. The main agenda of scientists would be to increase the efficiency of energy transfer by using the perovskite material. There are several factors that scientists need to work on to achieve their goals. Only time will tell what could be the future when it comes to replacing silicon with perovskite.
