Summary: A new secondary deposition approach was developed to increase quantum dot (QD) loading and enhance the performance of QD sensitized solar cells (QDSCs) without introducing new recombination centers. By creating a metal oxyhydroxide layer around QD presensitized photoanodes, the photovoltage, fill factor, and efficiency of the ZCISSe QDSCs were remarkably improved. This innovative method achieved a new certified power conversion efficiency (PCE) record of 15.20% for liquid-junction QDSCs.

Summary: In this study, a CuxS/GO composite hole transport layer is used to modulate the charge transfer efficiency of quantum dot-sensitized solar cells. The introduction of the CuxS/GO composite layer significantly reduces the normalized PL intensity of TiO2/CuInS2 photo-electrodes, indicating excellent charge separation properties. The charge recombination traps are also reduced under the CuxS/GO composite layer, leading to an effective improvement in the charge transfer efficiency of the solar cells. As a result, TiO2/CuInS2 quantum dot-sensitized solar cells with the CuxS/GO composite layer exhibit higher V-oc, FF and J(sc) values, resulting in an enhancement of the photovoltaic conversion efficiency from 4.85% to 6.07%.

Summary: Solar cells made of organic-inorganic metal halide perovskite have the potential to replace traditional silicon-based solar cells, but their efficiency is a major hurdle in commercialization. The use of suitable organic hole transporting materials can improve the efficiency of perovskite solar cells. Spiro-OMeTAD is the standard hole transporting material used, but its complex synthesis and purification steps make it cost-ineffective. Recently, hole transporting materials made of organic small molecules, such as carbazole, have shown better photovoltaic properties and cost-effectiveness. This review focuses on the design and synthesis strategies of carbazole-based hole transporting materials and evaluates their performance in perovskite solar cells.

Summary: Quantum dot-sensitized solar cells (QDSSCs) have unique characteristics that make them a promising solution to the energy-economy-environment dilemma. Researchers have been strategically addressing the challenges faced by QDSSCs, such as back transfer of electrons, recombination, and photocorrosion, to improve their performance. Interfacial layers (ILs) have proved beneficial in addressing these challenges, providing surface passivation, seeding quantum dots, and controlling back electron transfer. This review discusses the multifunctional roles of ILs in QDSSCs, characterization techniques, and future prospects.

Summary: We studied the exciton properties of the Mo0.6W0.4S2 alloy compared to pure MoS2 and WS2. The energy and line width of the exciton peaks in optical transmission spectra were found to decrease and increase, respectively, with increasing temperature. The exciton-phonon interactions in the alloy were closer to MoS2 than WS2, suggesting a larger amplitude of exciton wave functions on Mo atoms. TDDFT calculations successfully reproduced the experimental absorption spectra and indicated that Mo and W atoms are uniformly distributed among all layers in the alloy.

Summary: Rutile-TiO2 microspheres were synthesized by hydrothermal method and annealed at different temperatures. The influence of annealing temperature on the structural, optical, morphological, and humidity sensing performance of the microspheres was investigated. The study found that annealing temperature did not significantly affect the bandgap of rutile-TiO2, but it did affect the surface area, pore volume, and pore radius. The humidity sensor made from microspheres annealed at 600 degrees C showed excellent sensitivity, fast response, and recovery time.

Summary: Metal chalcogenide-based photodetectors have been extensively studied, but their performance is still unsatisfactory. In this work, thin films of Indium selenide (gamma-In2Se3) were synthesized using RF magnetron sputtering technique. The effects of annealing temperature on the properties of the synthesized thin films were thoroughly investigated. The results showed that higher annealing temperature improved the crystalline quality and optical properties of the films. Photodetectors fabricated using the synthesized gamma-In2Se3 thin films exhibited excellent stability, repeatability, and photoresponsivity.
