Abstract: A sensor may include a reflective electrode, a photoelectric conversion layer on the reflective electrode and including one or more photoelectric conversion materials, a semi-transmissive electrode on the photoelectric conversion layer, a light transmitting buffer layer on the semi-transmissive electrode, and a semi-transmissive auxiliary layer on the light transmitting buffer layer.

Abstract: A vehicle body includes a floor member, a support member coupled to an upper surface of the floor member, and a frame member coupled to an upper end of the support member to define a space between the floor member and the frame member, wherein the space is configured to house an item. The item may include a high-voltage battery.

Abstract: There are provided a high-strength hot-rolled steel sheet having excellent weather resistance used for containers and a method of manufacturing the same. A high-strength hot-rolled steel sheet having excellent weather resistance includes, by weight: C: 0.05 to 0.07%, Mn: 2.5% or less, Nb: 0.04 to 0.06%, Ti: 0.08 to 0.10%, Cu: 0.30 to 0.60%, Cr: 0.5 to 1.0%, and Ni: 0.15 to 0.30%, and the balance of Fe and other inevitable impurities. A method of manufacturing the hot-rolled steel sheet is also provided. A hot-rolled steel sheet provided has weather resistance by addition of Cu, Cr, and Ni and material characteristics of a tensile strength within the range of 800 to 900 MPa and a yield strength within the range of 700 to 800 MPa.
