Synthesis of four-armed triphenylamine-based molecules and their applications in organic solar cells
TL;DR: In this paper, two wide band gap four-armed triphenylamine (TPA)-based molecules (SM1 and SM2) with a donor-acceptor-donor structural core and a thiophene (Th) or TPA-Th segment as the arm have been designed and synthesized by use of Stille coupling reaction to further study the relationship between the structure and properties of 4-Argonne-TPA-based molecules.

Self-assembled monolayer modified copper(I) iodide hole transport layer for efficient polymer solar cells
Abstract: The morphology of the copper iodide (CuI) film as an inorganic p-type material has an important influence on enhancing the performance of polymer solar cells (PSCs). A self-assembled monolayer of 3-aminopropanoic acid (C3-SAM) was used on the surface of indium tin oxide (ITO) before depositing the CuI films. Consequently, a well-distributed and smooth CuI film was formed with pinhole free and complete surface coverage. The root mean square of the corresponding CuI film was reduced from 3.63 nm for ITO/CuI to 0.77 nm. As a result, the average power conversion efficiency (PCE) of PSCs with the device structure of ITO/C3-SAM/CuI/P3HT:PC61BM/ZnO/Al increased significantly from 2.55% (best 2.66%) to 3.04% (best 3.20%) after C3-SAM treatment. This work provides an effective strategy to control the morphology of CuI films through interfacial modification and promotes its application in efficient PSCs.
