Summary: To improve the stability and efficiency of perovskite-silicon tandem solar cells, reductions in recombination losses are necessary. This was achieved by combining a triple-halide perovskite with a piperazinium iodide interfacial modification, resulting in improved band alignment, reduced nonradiative recombination losses, and enhanced charge extraction. The tandem solar cells achieved high open-circuit voltages and certified power conversion efficiencies of up to 32.5%.

Summary: This study presents a monolithic hybrid tandem solar cell with an all-organic blend as the rear subcell, using metal-ion doped all-inorganic perovskite front subcells and a solution-processed ternary organic blend rear subcell. The use of dynamic hot-air deposition technology allows the fabrication and testing of the solar cells entirely in the open air, and passivation and selection layer treatments improve efficiency and reduce open-circuit voltage loss. The solar cells achieved a maximum efficiency of 23.07% and retained over 90% of the initial efficiency after 600 hours of continuous illumination.

Summary: This study investigates semitransparent inverted perovskite solar cells (PSCs) prepared with a spin-coated SnO2 buffer layer. The results show that the solution processed PCBM layer may not fully cover the perovskite film, leading to a band-bending effect at the PCBM/perovskite interface. The study helps to understand the dominant electrical losses in semitransparent inverted PSCs and can contribute to improving their performance.

Summary: This study discusses the performance limitations of concentrated perovskite solar cells (PCSCs) and proposes a solution to improve their efficiency. By performing optoelectronic simulations on low band gap PCSCs, the researchers find that increased light concentration leads to significantly increased bulk recombination, mainly due to the inferior transport ability of holes. By manipulating the perovskite layer and the hole transport layer (HTL), the carrier-transport capability is improved, resulting in PCSCs with high conversion efficiencies.

Summary: This paper reports on a bifacial all-perovskite tandem structure that achieves an equivalent efficiency of 29.3% under a back-to-front irradiance ratio of 30. By embedding a light-scattering micrometer-sized particle layer and using a nonacidic hole transport layer, the efficiency of semitransparent Pb-Sn cells is increased from 15.6% to 19.4%, enabling the fabrication of efficient bifacial all-perovskite tandem devices.

Summary: Unassisted solar water splitting by multijunction tandem photoelectrodes is achieved with the fabrication of monolithically integrated all-perovskite tandem photocathodes, delivering a high photovoltage of over 2 V and a photocurrentdensity of 12.5 mA cm(-2) at zero applied bias under simulated 1 sun illumination. The tandem photoelectrode demonstrates continuous operation in water for more than 120 h with less than 5% efficiency loss. Techno-economic analysis predicts a low levelized cost of hydrogen of less than $1/kg for all-perovskite tandem photoelectrodes, if device longevity is realized.

Summary: By studying the effect of seed layer thickness, growth time, and tin oxide coating on ZnO nanorods, the performance of dye-sensitized solar cells was optimized. The tin oxide coating significantly increased the short circuit current density, open circuit voltage, and fill factor of the cells, contributing to better electron transfer efficiency, increased dye loading, and reduced charge carrier recombination. The use of tin oxide coating on zinc oxide nanorods led to substantial improvements in PCE, J(sc), and V-oc, demonstrating the importance of tin oxide in enhancing the overall efficiency of the DSSCs.

Summary: Organic-inorganic perovskite solar cells have attracted attention due to their increased power conversion efficiency, but current density-voltage hysteresis remains a key challenge. Establishing a measurement protocol for reliable results is necessary. Hysteresis was found to be dependent on scan direction and time delay, with impedance spectroscopy revealing further insights into the effects of scan speed, delay, and frequency. Studies on hysteresis could help improve device performance and stability in the long term.

Summary: Research has shown that the photovoltaic performance and impedance spectra of perovskite solar cells vary significantly at different drying temperatures, with the best power conversion efficiency achieved at a drying temperature of 60 degrees Celsius. Determining the optimum drying temperature is crucial for ensuring the formation of perovskite crystals, increasing surface coverage of perovskite, and successfully extracting charges from the devices to achieve the highest performance.

Summary: This study reports a comparative investigation on quantum dot sensitized solar cells using polysulfide and iodide/triiodide as redox liquid electrolytes. The results show that the polysulfide-based device outperforms the iodide/triiodide-based cell in terms of overall power conversion efficiency, short circuit current, and fill factor. Additionally, significant improvements in series resistance and shunt resistance values were observed in the polysulfide-based device. This research demonstrates that using low-cost polysulfide electrolyte and carbon as counter electrode can achieve higher performance compared to using platinum as counter electrode in enhancing CdS QDSSCs.
