2019 journal article

Efficient Thick-Film Polymer Solar Cells with Enhanced Fill Factors via Increased Fullerene Loading

ACS APPLIED MATERIALS & INTERFACES, 11(11), 10794–10800.

By: C. Duan*, Z. Peng n, F. Colberts*, S. Pang*, L. Ye n, O. Awartani n, K. Hendriks, H. Ade, M. Wienk*, R. Janssen

author keywords: polymer solar cells; thick films; fill factor; fullerene loading
TL;DR: The results suggest enhanced electron mobility and suppressed bimolecular recombination upon increasing fullerene content in thick polymer:fullerene blend films, which are the result of larger fulleren aggregates and improved interconnectivity of the fullererene phases that provide continuous percolating pathways for electron transport in thick films.

Competition between Exceptionally Long-Range Alkyl Sidechain Ordering and Backbone Ordering in Semiconducting Polymers and Its Impact on Electronic and Optoelectronic Properties

ADVANCED FUNCTIONAL MATERIALS, 29(5).

author keywords: molecular design; organic electronics; polymer crystals; semiconducting polymers; sidechains
TL;DR: The observed influence of ordering between the moieties implies that improved molecular design could produce synergistic rather than destructive ordering effects and should greatly improve the coherence length of backbone ordering and thereby improve electronic and optoelectronic properties such as charge transport and exciton diffusion lengths.
