How perovskite in solar cells recrystallizes and why modified carbon nanotubes can help overcome the reproducibility problem by making use of this
Scientists at Tokyo Institute of Technology (Tokyo Tech) conducted an in-depth study on how carbon nanotubes with oxygen-containing groups can be used to greatly enhance the performance of perovskite solar cells. The newly discovered self-recrystallization ability of perovskite could lead to improvement of low-cost and efficient perovskite solar cells.
Our search for sustainable energy generation technology has led researchers to investigate various materials and their combinations in many types of devices. One such synthetic material is called “perovskite”, which is low-cost and easy to produce, and can be used in solar cells. Perovskite solar cells have attracted much attention because their power conversion efficiency (that is, their efficiency at turning sunlight into electricity) has seen dramatic improvements in recent years. However, it has proven difficult to implement them for large-scale energy generation because of a handful of issues.
