Aqueous PEDOT:PSS Formulation
Used for applications in OPV and perovskite solar cells
Clevios™ HTL Solar (CAS number 155090-83-8) is an aqueous PEDOT:PSS formulation designed for use in thin film electronics as an interfacial material. The advantage of the HTL Solar formulation is its improved wetting properties, particularly in inverted OPV cells, compared to the other PEDOT:PSS formulations in our catalogue.
PEDOT:PSS (HTL Solar) from Ossila was featured in the high-impact paper (IF 16.6), Ultra-high resolution imaging of thin films and single strands of polythiophene using atomic force microscopy, V. Korolkov et al, Nat. Commun., 10, 1537 (2019); DOI: 10.1038/s41467-019-09571-6; and paper (IF 17.6), Continuous, crystalline Sb2S3 ultrathin light absorber coatings in solar cells based on photonic concentric p-i-n heterojunctions, P. Büttner et al., Nano Energy, 103 (B), 107820 (2022); DOI: 10.1016/j.nanoen.2022.107820.

PEDOT and PEDOT:PSS Synthesis
PEDOT synthesis involves the oxidative chemical or electrochemical polymerization of EDOT monomer. The choice of counterions and polymerization method significantly affects the conductivity, work function, and stability of the resulting PEDOT polymer.
