Journal ArticleDOI
Realizing 19.05% Efficiency Polymer Solar Cells by Progressively Improving Charge Extraction and Suppressing Charge Recombination
TL;DR: In this paper , the authors improved the charge extraction and suppressed charge recombination of polymer solar cells through the combination of side-chain engineering of new nonfullerene acceptors (NFAs), adopting ternary blends, and introducing volatilizable solid additives.
Journal ArticleDOI
From binary to ternary solvent: morphology fine-tuning of D/A blends in PDPP3T-based polymer solar cells.
TL;DR: This work finds systematic variations in the surface texture, the bulk compositional morphology, and the crystallization behavior of the PDPP3T/PCBM system and relates them to device performance.
Journal ArticleDOI
Domain Purity, Miscibility, and Molecular Orientation at Donor/Acceptor Interfaces in High Performance Organic Solar Cells: Paths to Further Improvement
TL;DR: In this article, the authors used soft X-ray tools to study domain purity and interface structure for fullerene-based bulk heterojunction (BHJ) solar cells.
Journal ArticleDOI
10.8% Efficiency Polymer Solar Cells Based on PTB7‐Th and PC71BM via Binary Solvent Additives Treatment
TL;DR: In this paper, a polymer solar cell is fabricated based on the blend of PTB7-Th: PC71BM by using a mixed solvent additive of 1,8-diiodooctane and N-methyl pyrrolidone to optimize the morphology of the blend.
