摘要: Organic polymer semiconductor-based polymer solar cells (PSCs) have attracted considerable research interest due to having excellent electrical, structural, optical, mechanical, and chemical properties. In the past 20 years, considerable efforts have been made to develop PSCs. Generally, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is used as a hole transport layer (HTL) of the PSC to enhance hole extraction efficiency, but highly acidic PEDOT:PSS destroys an indium tin oxide (ITO) electrode and an active layer and thus reduces the lifetime of the device. To avoid this problem, some attempts have been made to develop inverted PSCs having different electron transport layers (ETLs). However, such a device has limited power conversion efficiency (PCE) due to low electron mobility of the ETL. Therefore, attempts have been made to enhance the PCE of inverted PSCs using indium gallium zinc oxide (IGZO) having optimized indium (In), gallium (Ga), and zinc (Zn) contents. Accordingly, inverted PSCs that have ZnO or IGZO (having varying In:Ga:Zn molar ratios) as an ETL and have an ITO/ETL/PTB7:PC71BM/MoO3/Al structure have been constructed. The PCE of the inverted PSC can be increased from 6.22% to 8.72% using IGZO having an optimized weight ratio of In, Ga, and Zn.

摘要: A method of measuring a distance to a satellite, which is performed by an electronic device, according to an exemplary embodiment of the present invention, the method comprises receiving a linearly polarized photon from and angular momentum per unit mass of the satellite the satellite; measuring an amount of rotation of the polarized photon, the rotation being induced by a space-time warpage due to gravity; and calculating a distance to the satellite by using the rotation amount of the polarized photon and the angular momentum per unit mass of the satellite. The distance to the satellite may be calculated by the following equation, sin Θ ( r ) ≅ - l obs rr s 1 - r s r , wherein ‘2Θ’ is the rotation amount of polarized photon, ‘lobs’ is the angular momentum per unit mass of the satellite, ‘r’ is the distance to the satellite, and ‘rs’ is the Schwarzschild radius of the Earth.
