Semitransparent perovskite solar cells (ST-PSCs) for building-integrated photovoltaics (BIPV) face the challenge of achieving high efficiency due to significant light loss. The SnO2 electron transport layer (ETL), utilized in n-i-p PSCs and prepared via the sol-gel method, is susceptible to aggregation on substrate, resulting in light scattering that diminishes absorption of the perovskite layer. In this study, we propose a strategy that combines atomic layer deposition (ALD) and sol-gel solution to deposit a bilayer SnO2 structure to address these issues.

Introduction Occupational health hazards are a significant concern for pathologists due to their unique work environment. These professionals face risks from prolonged microscope use, exposure to chemicals such as formalin, and handling sharp instruments, leading to issues such as musculoskeletal disorders and needlestick injuries. Addressing these hazards is crucial for their well-being and the overall efficiency of medical diagnostics.

Background: Sensory impairments, notably hearing loss (68% in those aged 70+) and vision loss (24%-50%), are prevalent in older individuals. We investigated the correlation between visual and hearing impairments in older adults, considering sociodemographic factors, mental health, and social support.
Methods: The study is part of The Serbian 2019 National Health Survey, conducted in 2019.

Phosphor-converted micro-light emitting diodes (micro-LEDs) are a crucial technology for display applications but face significant challenges in light extraction because of the high refractive index of the blue pump die chip. In this study, we design and experimentally demonstrate a nanophotonic approach that overcomes this issue, achieving up to a 3-fold increase in light extraction efficiency. Our approach involves engineering the local density of optical states (LDOS) to generate quasi-guided modes within the phosphor layer by strategically inserting a thin low-index spacer in combination with a metasurface for mode extraction.
