Two-dimensional (2D) layered nanomaterial heterostructures, arising from the combination of 2D materials with other low-dimensional species, feature a large surface area to volume ratio, which provides high density active sites for catalytic applications and (photo)electrocatalysis (PEC). Meanwhile, their electronic band structure electrical conductivity enable efficient charge transfer (CT) between material substrate, is essential activity. In recent years, researchers have demonstrated...
Metal halide perovskite materials have opened up a great opportunity for high-performance optoelectronic devices owing to their extraordinary properties. More than lead ones, stable and nontoxic bismuth perovskites exhibit more promise in future commercialization. In this work, we developed the first time photodetectors based on full-inorganic Cs3Bi2I9-xBrx modulate performance by varying x composition systematically. Among those self-powered photodetectors, Cs3Bi2I6Br3 shows best with...
Perovskite solar cells (PSCs) are demonstrating great potential to compete with second generation photovoltaics. Nevertheless, the key issue hindering PSCs full exploitation relies on their stability. Among strategies devised overcome this problem, use of carbon nanostructures (CNSs) as hole transporting materials (HTMs) has given impressive results in terms stability moisture, air oxygen, and heat.

Costs and toxicity concerns are at the center of a heated debate regarding implementation perovskite solar cells (PSCs) into commercial products. The first bottleneck could be overcome by eliminating top metal electrode (generally gold) underlying hole transporting material substituting both with one single thick layer conductive carbon, as in so-called carbon-based PSCs (C-PSCs). second issue, related to presence lead, can tackled resorting other structures based on less toxic metallic...
Within one decade, lead halide perovskite solar cells have reached power conversion efficiencies (PCEs) compatible with that of silicon cells.
