Perovskite: the material that allows a greener fabrication of transistors

Scientists make transistors using perovskite, overcoming a long-standing ion obstacle - Physicists find a way to make components for low-cost electronics using a material that's highly rated for its performance in next-gen solar cells and LEDs. Last updated on Tuesday 17 August 2021 - Physicists have found a way to make transistors using materials that are highly rated for their performance in next-generation solar cells and light-emitting diodes (LEDs). The researchers have overcome the problem of the material's ion content interfering with the flow of electronic current through a transistor. This breakthrough may pave the way for research into greener electronic components for low-cost electronic devices. Over the past decade, solution-processed metal-halide perovskites (a hybrid metal-organic material) have been a major focus of research into low-cost, high-efficiency solar cells and LEDs. Because of their ability to process at relatively low temperatures, perovskites are considered a greener alternative to silicon, not only for the fabrication of solar cells but also for transistors. A transistors is the building blocks of an integrated circuit, and the key component in many electronic devices.
