摘要： Multilayer organic electronic devices having an electron transport layer (ETL). The ETL is a film comprising an N-annulated perylene diimide (NPDI) compound having at least one pyrrole N—H bond and at least 1 equivalent of Cs2CO3 with respect to the NPDI compound and the number of pyrrolic N—H bonds in the NPDI compound. The ETL is positioned between the photoactive layer and the top electrode (cathode). Multilayer devices including the ETL are fabricated employing immiscible solvent methods. A method for making the ETL layers is provided which employs an ink formulation in which the NPDI compound is solubilized in a selected polar solvent by addition of at least one equivalent of Cs2CO3 respect to the NPDI compound. Exemplary polar solvents include ethanol, 1-propanol, ethyl acetate and mixtures thereof.

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.
