Summary: Wide-bandgap perovskite solar cells are crucial as top cells in perovskite-based tandem solar cells. However, poor band alignment with the charge transport layer and unwanted parasitic absorption in the top semitransparent perovskite solar cells limit the power conversion efficiency of tandem solar cells.

Summary: Tunable bandgaps in halide perovskites make them promising for developing tandem solar cells, which can surpass the radiative limit of single-junction solar cells. Combining perovskites with crystalline silicon can potentially achieve a high efficiency limit of 46%. However, current perovskite/c-Si tandem solar cells only achieve an efficiency of about 32.5%, indicating challenges and opportunities. This review discusses the operating mechanism, efficiency limit, and challenges in developing highly efficient and stable wide-bandgap perovskite front cells for commercialization.

Summary: This study investigates the influence of substrate temperature on Zinc Oxide (ZnO) thin films synthesized on glass substrates using low-cost spray pyrolysis technique. The results show that the films deposited at 450 degrees C have the best crystallinity and altered surface morphology. The increase in substrate temperature improves the crystallinity and reduces defects. Additionally, the films deposited at 450 degrees C exhibit minimum defects and can be used as ultraviolet photodetector material.

Summary: Multijunction solar cells can surpass the efficiency limits of single-junction devices. Metal halide perovskite solar cells, in combination with silicon and copper indium gallium selenide (CIGS) or as all-perovskite tandems, have shown promising results. Narrow-gap non-fullerene acceptors have also significantly improved the efficiencies of organic solar cells. In this study, perovskite-organic tandem cells with high efficiency and voltage are demonstrated, utilizing optimized charge extraction layers and an ultrathin metal-like indium oxide layer for interconnection. This milestone work outperforms the best perovskite single junctions and is comparable to perovskite-CIGS and all-perovskite multijunctions.

Summary: In this study, a tandem process of catalytic pyrolysis and catalytic chemical vapor deposition (CVD) was used to investigate the conversion of waste plastics to carbon nanomaterials, oil, and hydrogen. The effects of plastic types and feeding rate on the products and quality of carbon nanomaterials were explored. Results showed that high-density polyethylene (HDPE), lowdensity polyethylene (LDPE), and polypropylene (PP) produced carbon nanomaterials with fewer defects, making them more favorable for hydrogen and carbon nanomaterial production. The proposed tandem process shows great potential for upcycling waste plastics.

Summary: We developed a three-terminal ion-sensitive device (TTISD) as a sensor for the detection of glucose and arsenic dissolved in water. The device was fabricated using the e-beam evaporation and glancing angle deposition (GLAD) technique. The TiO2 nanowires (NWs) were grown by GLAD on the conducting nafion channel of the TTISD to immobilize the test specimens. This work presents a nano-hybrid platform for the detection of low-concentration glucose and high-concentration arsenic in drinking water, with a rapid response time of approximately 1 second.

Summary: This study modeled and analyzed perovskite solar cells based on Cs2AgBiBr6 with different electron transport layers and hole transport layers. The power conversion efficiency (PCE) reached saturation after the perovskite thickness reached 700 nm. Decreasing the carrier lifetime from 10(3) ns to 10(-1) ns led to a decline in PCE from 21.88% to 1.58%. Deep-level defects in the perovskite layer trapped carriers and increased carrier recombination. The carrier capture cross-sectional area greatly affected cell performance. Increasing temperature reduced carrier mobility and lowered the built-in potential (V (bi)) from 1.17 V to 0.98 V when raised from 300 K to 400 K. The optimal device, FTO/ZnO/Cs2AgBiBr6/NiO/Au, showed a maximum efficiency with V (oc) = 1.29 V, J (sc) = 20.69 mA cm(-2), fill factor = 81.72%, and PCE = 21.88%.

Summary: Metal halide perovskites are highly promising for photovoltaic applications in the solar industry due to their high efficiency, processability, chemical characteristics, and cost-effectiveness. However, their stability is a major concern, and potential-induced performance degradation (PID) has emerged as a prevalent risk. This study investigates the influence of PID on different perovskite device structures and evaluates their performance. The results show that CsPbI3-based solar cells exhibit the highest defect tolerance limit and the FTO/TiO2/CsPbI3/NiO/Au structure demonstrates better stability under PID.

Summary: Although perovskite solar cells (PSCs) have achieved a high efficiency of 25.7% after extensive research, their commercialization is hindered by the short lifespan of the organic part and charge transporting layers. To achieve long-term device stability, inorganic perovskite aligned with the hole transporting layer (HTL) could be an alternative. Delafossite CuCrO2 was synthesized using a green method and characterized. The simulation study using CuCrO2 as HTL in a Pb-free RbGeI3-based inorganic perovskite device showed a maximum efficiency of 23.8% under optimized conditions.

Summary: Phototransistors based on blended MAPbI3 perovskite nanocrystals and P3HT exhibit higher absorption coefficient and unique optical properties, resulting in faster response time and more stable photoresponse compared to pure P3HT phototransistors. The optimized device with a 2:1 weight ratio of MAPbI3 nanocrystals to P3HT achieves an ILIGHT/IDARK ratio of 123, which is 63% higher than in pure P3HT phototransistors. These phototransistors may have potential applications as tunable photosensors due to their ease of fabrication and high sensitivity.

Summary: A facile electrodeposition technique was used to design a copper sulfide/cobalt sulfide biphasic composition on nickel foam for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The bi-phasic CoSx/CuSx@NF catalyst showed minimal overpotentials of 230 mV at 10 mA cm-2 and 390 mV at 100 mA cm-2 for OER, and 113 mV at 10 mA cm-2 for HER. The interconnected nanosheet and nanoflower structure in CoSx/CuSx@NF provided high surface area and lowered interfacial resistance, leading to improved OER and HER activity.
