Effect of Chemical Modification of Fullerene-Based Self-Assembled Monolayers on the Performance of Inverted Polymer Solar Cells
TL;DR: In this paper, a series of fullerene-based self-assembled monolayers (C60-SAMs) containing different anchoring groups (catechol, carboxylic acid, and phosphonic acid), linkage location, and functionalization was investigated by processing the SAM through either a solution immersion technique or a solution spin-coating method.
Journal ArticleDOI
Low-temperature processed high-performance flexible perovskite solar cells via rationally optimized solvent washing treatments
TL;DR: In this article, a planar-heterojunction (PHJ) perovskite (CH3NH3PbI3) solar cells fabricated through low-temperature annealing are demonstrated.
Journal ArticleDOI

TL;DR: In this article, the authors show that incorporating a third component with lower miscibility and higher lowest unoccupied molecular orbital (LUMO) level into the state-of-the-art PM6:Y6 system can significantly enhance the performance of devices.
Journal ArticleDOI
High Performance Amorphous Metallated π-Conjugated Polymers for Field-Effect Transistors and Polymer Solar Cells
TL;DR: The best solar cell performance is based on a high field effect mobility (μh = 1.0 × 10−2 cm2 V−1 s−1) polymer blended with PC71BM leading to a power conversion efficiency of PCE = 4.13% as discussed by the authors.
