Provided is a solar cell including a pair of electrodes, and a photoelectric conversion layer of chalcopyrite structure sandwiched between the pair of electrodes. At least one of the pair of electrodes, adapted to serve as a transparent electrode, has a nitrogen-containing layer composed with the use of an organic compound containing a nitrogen atom, and an electrode layer containing a metal of the Group 11 of the periodic table, which is provided to be laminated on the nitrogen-containing layer, thereby improving the photoelectric conversion efficiency.

Solar cell and transparent electrode

A flexible secondary battery having flexibility, wherein the flexible secondary battery is constituted by a lithium ion secondary battery, and contains one or more kind of softening agent(s) selected from acrylic-based polymers and diene-based polymers in an active substance layer of at least one of a positive electrode and a negative electrode, and the lithium ion secondary battery has an internal depressurization degree of from 10 to 1,000 Pa, is constituted.

Flexible secondary battery with polymer softening agent and internal depressurization

A radiographic image detector to detect radiation applied thereto and obtain radiographic image information, includes: an internal power supply to supply power to drive units at least upon imaging; a communication unit to perform communication with an external device; a connection terminal connectable to a connection unit which performs at least one of charging of the internal power supply and the communication with the external device; a storing unit to store at least one of an image and information; a connection detecting unit to detect whether the connection terminal is connected to the connection unit; a state checking unit to check a state of each unit; and a control unit to control the state checking unit such that the state checking unit checks the state of each unit when the connection detecting unit has detected that the connection unit is connected to the connection terminal or disconnected therefrom.
