Abstract: In this photoelectric conversion element wherein group III-IV compound semiconductor single crystals containing zinc as an impurity are used as a substrate, the substrate is increased in size without lowering conversion efficiency. A heat-resistant crucible is filled with raw material and a sealant, and the raw material and sealant are heated, thereby melting the raw material into a melt, softening the encapsulant, and covering the melt from the top with the encapsulant. The temperature inside the crucible is controlled such that the temperature of the top of the encapsulant relative to the bottom of the encapsulant becomes higher in a range that not equal or exceed the temperature of bottom of the encapsulant, and seed crystal is dipped in the melt and pulled upward with respect to the melt, thereby growing single crystals from the seed crystal.

Abstract: Generating an interactive discovery feed of place of interest items (POIs) relevant to a user is provided. A relevant POI discovery feed system curates a collection of narratives about various POIs from multiple sources and generates a plurality of POI content feed items including content items (e.g., photos, maps, links to additional information or related POIs) extracted from the collection of narratives. The system determines a set of POIs relevant to a user based on user-selected topics of interest and user preferences inferred from signals generated from user interactions with the system, and generates a discovery feed of POI content feed items associated with the set of relevant POIs for display to the user. In some examples, the items are presented in a card-based UI. Users are enabled to easily discover new places, view photos, and learn more about POIs in a consistent presentation of POI-related content feed items.

Abstract: The present invention increases the conversion efficiency of a photoelectric conversion element that uses cadmium zinc telluride or cadmium telluride (Cd(Zn)Te) compound semiconductor single crystals containing a group 1A element as an impurity. A heat-resistant pot is filled with raw material and a group 1A element, which is reacted with a portion of the raw material, and the container is heated, thereby melting the raw material into a melt and diffusing the dissociated group 1A element in the melt, producing single crystals from the melt. Compound semiconductor single crystals for photoelectric conversion elements having a hole concentration of 4×1015 cm?3 to 1×1018 cm?3 are produced in this manner. Using a substrate (2) that has been cut out from the compound semiconductor single crystals for photoelectric conversion elements enables the conversion efficiency of a photoelectric conversion element (10) to be increased.
