The present invention provides a solar cell including: a laminate having an electrode, a counter electrode, and a photoelectric conversion layer disposed between the electrode and the counter electrode; and an encapsulation material covering the counter electrode to encapsulate the laminate, the photoelectric conversion layer including an organic-inorganic perovskite compound represented by the formula: R-M-X, R representing an organic molecule, M representing a metal atom, X representing a halogen atom or a chalcogen atom, the encapsulation material including a resin having at least one skeleton selected from the group consisting of polyisobutylene, polyisoprene, and polybutadiene.

Solar cell

The present invention aims to provide a method of producing a solar cell which can produce a porous inorganic oxide layer that has a high porosity and contains less impurities even by low-temperature firing. The present invention also aims to provide a solar cell produced by the method of producing a solar cell. The present invention directs to a method of producing a solar cell. The method includes: applying an inorganic oxide paste that contains inorganic oxide fine particles, a binder resin, and an organic solvent to a surface of a base to form an inorganic oxide layer on the base, the base including a conductive layer as an outermost layer thereof, the surface being a conductive layer-side surface; firing the inorganic oxide layer; irradiating the inorganic oxide layer with active energy rays or subjecting the inorganic oxide layer to ozonolysis to form a porous inorganic oxide layer; and laminating a semiconductor on the porous inorganic oxide layer.

Method for manufacturing solar cell, and solar cell

A design information providing system, which does not allow continuation of manufacturing of products unless a patent license contract is concluded, includes a terminal apparatus () of a user manufacturing a product (BD player ()) and includes a patent license issuing server () issuing, to the terminal apparatus (), a contract certificate () certifying the conclusion of the contract, when a contract for a license necessary for manufacturing the BD player () is concluded with the user of the terminal apparatus (). Further, the design information providing system includes a design information providing server (an encryption key issuing server ()) transmitting an encryption key () to the terminal apparatus () on condition of the confirmation of the contract certificate (), when a request for design information (encryption key ()) unique to the BD player () is transmitted from the terminal apparatus ().

Information providing system and design information providing server

A DVD terminal () makes a request for sending a sub-content to an authentication server () (in this case, attaches the 'model name and serial number' of the DVD terminal ()) (S). The authentication server () generates a random number R (S) and sends it to the DVD terminal () (S). The DVD terminal () reads a terminal key and a terminal ID that are stored in a terminal information memory unit (), decrypts the received random number R using a terminal key (SK_X) (S) and sends this and the terminal ID (ID_X) to the authentication server () (S). The authentication server () verifies the random number R and the terminal ID that are received from the DVD terminal () and encrypted, and judges whether the DVD terminal () is the authenticated terminal or not (S).

Authentication server, method and system for detecting unauthorized terminal

A method and an apparatus are provided, which enable a user's standby time to be shortened or utilized effectively in the course of recording/reproduction of information with respect to an optical disk. Information recorded on a disk is reproduced preferentially, and after counting for a predetermined period of time, recording learning is conducted. Alternatively, management information is reproduced preferentially over recording learning, and recording learning is conducted while a user is confirming this information. Alternatively, the possibility of recording on a disk is identified, and reproduction preference or recording learning preference processing is conducted based the possibility. Alternatively, a rotation speed of a disk is controlled to be variable or constant, based on the possibility of recording.
