Roll-to-roll fabrication of flexible printed perovskite solar cells under ambient conditions

Researchers have been able to successfully replace the expensive metal layer of the top electrode of perovskite solar cells with a less-expensive carbon-based electrode that can also be applied using roll-to-roll techniques. This new electrode deposition method involves the deposition of carbon and silver on a detachable plastic (PET) substrate first, with the dried electrode then pressed onto the top of the perovskite solar cell. The PET layer is then removed and can be reused.

MXene with its X factor may help downscaling 2D transistors

Researchers show how MXenes' rich chemistry can be used to create doping-free 2D transistors with intrinsically low resistive contacts while maintaining balance mode operation. With a suitable functional termination, MXenes can become a semiconductor or a metal with a different work function. The researchers exploit this unique property of MXene to propose a Schottky barrier transistor, which can be implemented with a bare MXene by converting it to a semiconductor in the channel region with strategic functionalization.
