Content processing apparatus and content display apparatus based on location information

Abstract: The present invention receives list content providing location conditions in a list organized by location conditions in which a reference destination of location-dependent content, being content assigned correspondence to geographical location information, is compiled for each location condition, sent from a content communication server; receives the sent location information; generates area-specific list content comprising information on location-dependent content corresponding to location information, by extracting a list organized by location conditions, in which location conditions matching location information are provided, from the list content; and outputs the area-specific list content.

Compositional Engineering for Thermally Stable, Highly Efficient Perovskite Solar Cells Exceeding 20% Power Conversion Efficiency with 85 °C/85% 1000 h Stability.

Abstract: Perovskite solar cells have received great attention because of their rapid progress in efficiency, with a present certified highest efficiency of 23.3%. Achieving both high efficiency and high thermal stability is one of the biggest challenges currently limiting perovskite solar cells because devices displaying stability at high temperature frequently suffer from a marked decrease of efficiency. In this report, the relationship between perovskite composition and device thermal stability is examined. It is revealed that Rb can suppress the growth of PbI2 even under PbI2 -rich conditions and decreasing the Br ratio in the perovskite absorber layer can prevent the generation of unwanted RbBr-based aggregations. The optimized device achieved by engineering perovskite composition exhibits 92% power conversion efficiency retention in a stress test conducted at 85 °C/85% relative humidity (RH) according to an international standard (IEC 61215) while exceeding 20% power conversion efficiency (certified efficiency of 20.8% at 1 cm2 ). These results reveal the great potential for the practical use of perovskite solar cells in the near future.

Electrochemical Characterization of Activated Carbon‐Fiber Cloth Polarizable Electrodes for Electric Double‐Layer Capacitors

Abstract: Electrochemical characterization has been carried out for two types of phenolic resin‐based activated carbon‐fiber cloths (ACFC)—ACFC(a) and (b)—as polarizable electrodes. The specific surface areas of ACFC(a) and ACFC(b) were 1630 and 1060 m2g−1, respectively. The differential capacitance of ACFC(a) in organic electrolyte, which was determined by cyclic voltammetry, was 113 F g−1 at 0.1V vs. SCE. The capacitive current of ACFC(a) was almost constant in the range between −1.5 and 1.5V vs. SCE at 25° and −25°C, while that of ACFC(b) decreased under cathodic polarization, especially at −25°C. In accordance with the result of cyclic voltammetry, the temperature dependence of capacitance in the electric double‐layer capacitors with ACFC(a) and an organic electrolyte was small, and that of the capacitors with ACFC(b) was large. It was found that the temperature dependence of the capacitors with ACFC and an organic electrolyte was mainly influenced by the pore size distribution of ACFC electrodes.

Electronic device, content reproduction control method, program, storage medium, and integrated circuit

Abstract: In order to play back a content while managing the right on use of the content, such as a total time of playback of the content, an electronic device stores right information in a right temporary storage unit 59 and judges whether or not use of the content is permitted, in a process of decoding a frame. Also, the electronic device updates the right information stored in the right temporary storage unit 59. When the frame to be played back is the one at apredeterminedposition in order, the electronic device stores the right information stored in the right temporary storage unit 59 into a storage area 20.
