Companies say they are close to commercializing cheap perovskite films that could transform the solar energy sector – but are they being overly optimistic?
The robotic hotel in Japan tests new solar cells
The Henn na hotel in Nagasaki, Japan, is one of the hotels experimenting with futuristic technology. It claimed to be the world’s first hotel operated by robots in 2015 – but it scaled back automation after the robots garnered negative reception from some guests and didn’t reduce costs. Now, Henn na hotel is testing another innovation that is drawing attention: since December, the hotel’s billboard has been powered by a wall of standard solar cells installed on the hotel grounds. These cells utilize micrometer-thin technology made from materials called perovskites, which have evolved in just a decade from being a lab curiosity to a promising new opportunity in solar energy.
Companies’ optimistic forecasts
Companies claim they are very close to commercializing cheap perovskite films that could revolutionize the solar energy field. However, are these expectations overstated? There are some doubts about the ability of these films to achieve the required performance and long-term stability. This technology may face commercial and technical challenges before it is ready for widespread use.
Potential applications of perovskite
Thin perovskite films are extremely promising solar cells, as they can be used in a wide range of applications. They could be useful in places where it is difficult to install traditional solar cells, such as windows, glass surfaces, and wearable devices. This technology could contribute to increasing energy sustainability and reducing energy costs in the future.
Technical and commercial challenges
Despite the growing interest in perovskite films, there are technical and commercial challenges that need to be overcome before this technology is ready for widespread use. Among the technical challenges are ensuring long-term performance stability and durability, in addition to improving photovoltaic conversion efficiency. Commercially, manufacturing processes must be improved and production costs reduced to make this technology more economically attractive.
Future developments in perovskite films
As advancements in perovskite films continue, this technology may become more ready for widespread use in the future. Improvements in photovoltaic conversion efficiency, performance stability, and lower production costs could make this technology a sustainable and economical alternative to traditional solar energy.
