Managing iodine formation is crucial for realising efficient and stable perovskite photovoltaics. Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a widely adopted hole transport material, particularly for perovskite solar cells (PSCs). However, Improving the performance and stability of PEDOT:PSS based perovskite optoelectroni...
While recent advances have demonstrated highly efficient and stable perovskite light-emitting diodes (LEDs), blue perovskite LEDs still show low performance compared to green, red, near IR counterparts. Despite perovskites being well-known for their defect tolerance, blue perovskites are highly vulnerable to defects, which introduce deep trap state...
Self-powered near-infrared (NIR) photodetectors are essential for surveillance systems, sensing in IoT electronics, facial recognition, health monitoring, optical communication networks, night vision and biomedical imaging. However, silicon commercial detectors need external power to operate and cooling to suppress large dark currents. This work de...
We report the photothermal actuation of 4D-printed tools which are SLA-printed employing a customized photocurable resin. The tools can be applied in soft robotic applications stimulated by a heat lamp at a near ambient temperature of 15–45 °C.

Although the use of verditer, a synthetically produced copper carbonate pigment chemically analogous to azurite (Cu3(CO3)2(OH)2), in early modern wall paintings is regularly reported in grey literature, its detection in wall paintings is typically unavailable in a public forum. This article focusses on two particular samples (M9 and T1) initially s...
The fabrication of scalable all-perovskite tandem solar cells is considered an attractive route to commercialize perovskite photovoltaic modules1. However, the certified efficiency of 1-cm2-scale all-perovskite tandem solar cells lags behind their small-area (approximately 0.05-cm2) counterparts2,3. This performance deficit originates from inhomoge...
Obtaining micron-thick perovskite films of high quality is key to realizing efficient and stable positive (p)-intrinsic (i)-negative (n) perovskite solar cells1,2, but it remains a challenge. Here we report an effective method for producing high-quality, micron-thick formamidinium-based perovskite films by forming coherent grain boundaries, in whic...
This prospective and performance summary provides a view on the state of the art of emerging non-volatile memory (eNVM) in the semiconductor industry. The overarching aim is to inform academic researchers of the status of these technologies in industry, so as to help direct the right academic research questions for future materials and devi...
