Replacing gold and boosting stability: carbon as Holy Grail for perovskite solar cells.

In the quest for sustainable materials quasi-solid-state (QS) electrolytes in aqueous dye-sensitized solar cells (DSSCs), novel bioderived polymeric membranes were prepared this work by reaction of preoxidized kraft lignin with poly(ethylene glycol)diglycidylether (PEGDGE). The effect PEGDGE/lignin relative proportions on characteristics obtained was thoroughly investigated, and clear structure-property correlations highlighted. particular, glass transition temperature found to decrease...

Manufactured globally on industrial scale, cyclodextrins (CD) are cyclic oligosaccharides produced by enzymatic conversion of starch. Their typical structure truncated cone can host a wide variety guest molecules to create inclusion complexes; indeed, we daily use CD as unseen components food, cosmetics, textiles and pharmaceutical excipients. The synthesis active material composites from resources enable or enlarge the effective utilization these products in battery industry with some...

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...

Indeed, spectra a-DSSCs show two peculiar (and unreported) features that not observed in organic-based DSSCs. higher frequency one (R45°) likely associated slowdown diffusion...

An essential component of a working electrode is the conductive additive: whether it used in very low amounts or constitutes matrix, its electrochemical response not negligible. Commercially diffused carbon black species (i.e., Super P, C65, and C45) still lack an in-depth characterisation emerging field potassium-ion battery systems, which are on way towards large-scale stationary storage application. Thus, this work aims to provide strong tools discriminate their active role such secondary...
