High Open‐Circuit Voltage Cs₂AgBiBr₆ Carbon‐Based Perovskite Solar Cells via Green Processing of Ultrasonic Spray‐Coated Carbon Electrodes from Waste Tire Sources

Abstract

Invited for this month cover is the group of Teresa Gatti at the Justus Liebig University (JLU) in Giessen, Germany, the group of Federico Bella at Politecnico di Torino (POLITO), Italy, and the group of Francesco Lamberti at the University of Padova (UNIPD), also in Italy. The image shows how waste tires can be converted in a conductive carbon powder that undergoes a green processing step to produce carbon electrodes for lead‐free perovskite solar cells. Similar devices can be employed to harvest indoor light in order to power the Internet of Things (IoT) ecosystem. The Research Article itself is available at 10.1002/cssc.202201590.

First-Principles Study of Group VA Monolayer Passivators for Perovskite Solar Cells

“…The PSCs have also been used for converting light to electricity for electrocatalytic hydrogen production . Despite their excellent performance, , long-term operational stability remains the main obstacle for its commercialization. The exposure to moisture and oxidation, thermal stress, and ion migration would deteriorate the PSCs and cause the efficiency loss .…”

Myth behind Metastable and Stable n-Hexylammonium Bromide-Based Low-Dimensional Perovskites

“…Perovskite solar cells (PSCs) have achieved rapid progress with the best certified single-junction power conversion efficiency (PCE) of 25.7% . Perovskites exhibit outstanding optoelectronic properties including a high optical absorption cross-section, low exciton binding energies, long-range charge carrier diffusion lengths, and easy tuning of the band gaps. − Nevertheless, the improvement in device efficiency and stability is always the main challenge for the commercialization of PSCs, and the solution to both issues is highly related to the reduction of defects. , For example, the open-circuit voltage ( V oc ) of PSCs can be unfavorably lowered by the occurrence of non-radiative recombination at defected sites, the ion migration under a working built-in electric field, and light-soaking-induced structural degradation. − For large-scale applications of lead halide perovskites, the use of a toxic lead element and the heavy consumption of other related raw materials are another critical consideration for the environmental-friendly and sustainable development of this photovoltaic technology. , Recently, using recycled materials for the device fabrication and recycling the chemical components in used PSCs have been reported as some promising means for practical resource saving and recovery. − …”

The effect of boron doping on the optical, morphological and structural properties of Cu3SbS3thin films preparedviaspin coating

“…14,15 To overcome these hurdles, new PV absorber materials based on inexpensive, non-toxic, chemically stable and earth-abundant elements have been investigated to produce materials with easily controllable stoichiometries, low defect densities and good optoelectronic properties. 13,[16][17][18] Copper antimony sulfide (CAS) compounds have been recently seen as a good alternative to conventional materials as they have suitable optical and electrical properties for PV applications, and good-quality crystals can be grown at lower temperatures (B400-600 1C), unlike commonly used CIGS (B986 1C), CdTe (B1041 1C) and CZTS (B990 1C) thin films (Fig. 1).…”
