In Situ Study the Dynamics of Blade‐Coated All‐Polymer Bulk Heterojunction Formation and Impact on Photovoltaic Performance of Solar Cells

Nannan Yao, Qunping Fan, Zewdneh Genene, Heng Liu et autres

All‐polymer solar cells (all‐PSCs) have achieved impressive progress by employing acceptors polymerized from well performing small‐molecule non‐fullerene acceptors. Herein, the device performance and morphology evolution in blade‐coated all‐PSCs based on PBDBT:PF5–Y5 blends prepared from two different solvents, chlorobenzene (CB), and ortho‐xylene (o‐XY) …

A mesoscopic lattice model for morphology formation in ternary mixtures with evaporation

Mario Setta, Vì C. E. Kronberg, Stela Andrea Muntean, Ellen Moons et autres

We develop a mesoscopic lattice model to study the morphology formation in interacting ternary mixtures with the evaporation of one component. As concrete potential application of our model, we wish to capture morphologies as they are typically arising during the fabrication of …

In Situ Optical Spectroscopy Demonstrates the Effect of Solvent Additive in the Formation of All-Polymer Solar Cells

Yanfeng Liu, Qunping Fan, Heng Liu, Ishita Jalan et autres

1-Chloronaphthalene (CN) has been a common solvent additive in both fullerene- and nonfullerene-based organic solar cells. In spite of this, its working mechanism is seldom investigated, in particular, during the drying process of bulk heterojunctions composed of a donor:acceptor mixture. In this …

Quantitative analysis of phase formation and growth in ternary mixtures upon evaporation of one component

Stela Andrea Muntean, Vì C. E. Kronberg, Matteo Colangeli, Adrian Muntean et autres

We perform a quantitative analysis of Monte Carlo simulation results of phase separation in ternary blends upon evaporation of one component. Specifically, we calculate the average domain size and plot it as a function of simulation time to compute the exponent of …
