VIP: Metal–Polymer Hybrid Architectures as Novel Anode Platform for Microbial Electrochemical Technologies
Habitat for electro-bacteria: The feasibility of using polymer–metal hybrid structures as anode materials for bioelectrochemical systems, such as microbial fuel cells, is demonstrated. The potential of such hybrid materials lies in virtually unlimited possibilities of designing structured, porous high-performance electrodes with low gravimetric density, low amount of necessary metals like copper, and high specific conductivity.

Dig deeper–Solution at the bottom! Recent developments of metal oxide-based electron-transporting layers (ETLs) for high performing, stable perovskite solar cells (PSCs) are reviewed. Various methodologies to modify existing ETLs, the first deposited layer in regular architecture PSCs, are highlighted, and the effects of these modifications are considered towards the design of a cell structure with high performance and stability.

Now in 3D! A three-dimensional structure comprising a graphene aerogel decorated with cobalt phosphide nanoparticles (CoP/GA) is prepared to serve as electrocatalyst in the hydrogen evolution reaction (HER). The unique structure efficiently prohibits the dissolution/aggregation of the CoP nanoparticles, exposes a large active surface area, and provides multidimensional electron/ion transport pathways, resulting in excellent catalytic activity with high stability.

Mix, spin, go! Perovskite solar cells based on pinhole-free perovskite–C70 fullerene blend films deposited on fluorine-doped tin oxide (FTO)-coated glass substrates, without a specific electron-transporting/blocking layer, are fabricated and characterized. Enhanced photovoltaic performance and stability with respect to traditional compact TiO2-based cells is achieved for these simplified devices under continuous AM 1.5 G simulated sunlight, without the need for encapsulation.

PolyTPAs for stable PSCs: Poly(triarylamine) with methylphenylethenyl functional groups (V873) is used as a hole-transporting material in perovskite solar cells (PSCs). Devices employing V873 reach a power conversion efficiency of 12.3 % without any additives, and enable stable operation under 1 sun at maximum power point tracking and under elevated temperature (85 °C). This result shows remarkable progress towards stable PSCs under real working conditions and industrial stress tests.

Under cover: Perovskite solar cells are fabricated using perovskite active layers doped with fluorinated imidazolium-based molecules. These additives significantly increase the stability of the resulting solar cell device owing to the electron-withdrawing character of the fluorinated salt together with its hydrophobicity, and induce structural and functional changes to the resultant perovskite, leading to stable power conversion efficiency.
