Summary: With the development of optoelectronic devices towards miniaturization and flexibility, conventional submillimeter rigid encapsulation techniques are inadequate. This study proposes a nanometer to micrometer scale organic/inorganic hybrid thin film encapsulation (TFE) with self-cleaning ability, low water vapor transmittance rate, and super-hydrophobic performance. The TFE shows excellent barrier improvement and optical properties, making it a promising solution for the development of optoelectronic devices.

Summary: This study focuses on improving the flexibility of thin film encapsulation (TFE) for flexible OLEDs by selecting appropriate polymers. The elastic modulus and surface energy of four different polymers were compared, and it was found that lowering these factors improved flexibility. The interaction between the polymer and aluminum oxide (Al2O3) did not greatly influence flexibility, but the penetration depth of Al2O3 was important.

Summary: In this study, a flexible silicon thin-film transistor (TFT) on a plastic substrate was fabricated to analyze the major influencing factors of flexible devices under bending conditions. Experimental and modeling results showed that the bending radius and device dimensions significantly affected the radio-frequency (RF) performance of the flexible TFT. The carrier mobility and electric field increased with larger bending strains, leading to better RF performance.

Summary: Indoor photovoltaics (IPVs) are promising for powering the Internet of Things. The power conversion efficiency depends on the match between indoor light spectra and the band gap of the light absorbing layer. Metal-halide perovskites, with tunable band gaps, show potential but high bromine content leads to low open-circuit voltage (V-OC). By introducing iodine-rich compounds, the V-OC of perovskite IPVs can be increased up to 1.05 V under 1000 lux illumination, setting a record efficiency of 36.36%.
