Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction

open access: yesAdvanced Materials, EarlyView.
Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.
