Infrared absorbing polymer, infrared absorbing/blocking film, photoelectric device, organic sensor, and electronic device

A sensor includes a first electrode, a second electrode facing the first electrode, and a light absorbing layer between the first electrode and the second electrode. The light absorbing layer may have a first absorption spectrum having a first absorption peak in a first infrared wavelength region and a second absorption peak in a second infrared wavelength region, the second infrared wavelength region being a longer wavelength region than the first infrared wavelength region. The second absorption spectrum does not at least partially overlap with the first absorption spectrum. The second absorption spectrum may have a lower absorption intensity than the first absorption spectrum. An external quantum efficiency (EQE) spectrum that is amplified in the second infrared wavelength region is exhibited in the sensor.

Sensors and electronic devices

A solar cell includes an active layer between a first electrode and a second electrode, and a transport layer between the active layer and one of the first or second electrodes. A plurality of nanoparticles are included in at least one of the active layer or the transport layer. The nanoparticles may have the same or different shapes or sizes and may be spaced differently based on location. The nanoparticles may be made of metal or a different material and the active layer may be made from an organic photovoltaic material.

Organic solar cell and manufacturing method thereof

A method of forming a thin film includes coating one side of a transferring stamp including a hydrophilic polymer layer with a hydrophilic solution to form a transfer layer, and transferring the transfer layer to the substrate.

Method of forming a thin film and an electronic device

Disclosed is a method of reading data from a memory including a NAND cell array for performing communications via a serial peripheral interface (SPI) bus. The method includes sequentially receiving inputs of a block address, a word-line address, and a bit-line address of the NAND cell array; and starting to output data written in the NAND cell array immediately after the bit-line address is completely input. In this case, the sequential receiving of the inputs is performed via one input terminal.

Memory, and method of reading data from the memory

A composition for an organic thin film may include a first compound having a linear alkylene oxide moiety and a haloalkyl moiety, and a second compound having conductivity and being capable of controlling a work function.

Composition for organic thin film, organic thin film, and electronic device including the organic thin film
