The efficiency of antimony selenide (Sb2 Se3 ) solar cells is still limited by significant interface and deep-level defects, in addition to carrier recombination at the back contact surface. This paper investigates use lithium (Li) ions as dopant for Sb2 films, using hydroxide (LiOH) a medium. Surprisingly, LiOH solution not only reacts surface film but also penetrate inside along (Sb4 Se6 )n molecular chain. First, Li modify grain boundary's type create an electric field between p-type...
Abstract Perovskite solar cells have become a leading contender in next‐generation photovoltaic technologies due to their high efficiency and low‐cost potential. Managing the deep defects present effectively crystal lattice at interfaces is essential for enhancing performance longevity of perovskite cells. Here, perovskite's crystallization modulation interfacial defect passivation are achieved by developing guanidinium iodide (GAI)‐based surface strategy. The integration GAI passivates...
The brain's function can be dynamically reconfigured through a unified neuron–synapse architecture, enabling task-adaptive network-level topology for energy-efficient learning and inferencing. Here, we demonstrate an organic neuristor utilizing ferroelectric–electrolyte dielectric interface. This enables tunable short- to long-term plasticity reconfigurable logic-in-memory functions by controlling the interfacial interaction between electrolyte ions ferroelectric dipoles. Notably, short-term...
The wide-bandgap and p-type semiconductor layer plays a crucial role in the antimony selenide (Sb2Se3) solar cells, as it can provide carrier confinement inhibit interface recombination. In this work, tellurium (Te) thin is innovatively applied superstrate Sb2Se3 which further situ oxidized to (3.67 eV) oxide (TeOx). Experimental results indicate that both Te TeOx layers enhance built-in potential depletion width of devices reduce nonradiative recombination at back interfaces. Furthermore,...

A Sb<sub>2</sub>Se<sub>3</sub> device based on SnO<sub>2</sub> with the highest efficiency has been obtained by adding ultrathin CdS between FTO and film.
Antimony selenide (Sb2Se3) has attracted considerable attention for its simple composition, nontoxic nature, and abundance. However, the efficiency of Sb2Se3 solar cells is limited by low carrier concentration high recombination rate at interface between Au layer. For this paper, KOH solution used as etchant was to increase cells. The not only reacts with (etching surface) but also diffuses inside film. This study unexpectedly demonstrates that increases doping density improves back contact...

Neuromorphic optoelectrical synapses have shown great potential in edge artificial intelligence (AI) for energy-efficient sensory computing. However, environmental noise and device nonidealities pose immense challenges to the inference accuracy robustness of neuromorphic devices networks. Here, inspired by hierarchical biological vision system, self-powered organic optoelectronic synaptic devices, which benefit from a simple asymmetric-electrode structure, are demonstrated. The...
