A Polymer Hole Extraction Layer for Inverted Perovskite Solar Cells from Aqueous Solutions

Poly(Phenylene vinylene) anionic polyelectrolyte (PVBT-SO 3 ) was found to be an efficient hole extraction layer for inverted perovskite solar cells. It can be cast from an aqueous solution and does not require thermal annealing for improved device performance. The devices show maximum solar cell efficiency of 15.9% and exhibit improved stability under ambient conditions and enhanced charge extraction.

Hydrophilic Conjugated Polymers Prepared by Aqueous Horner–Wadsworth–Emmons Coupling

The synthesis of hydrophilic conjugated polymers typically relies on organometallic coupling methodologies. Here we present an approach to prepare polar poly(arylene–vinylene)s (PAVs) in water using the Horner–Wadsworth–Emmons (HWE) reaction. Here, the additional preparation of discrete arylene vinylene (AVs) afforded insight into HWE kinetics and regioselectivity. Nine novel PAVs and AVs were synthesized, characterized by UV–vis absorption and ultraviolet photoelectron spectroscopy, and studied for their utility in sensing and photovoltaic applications.
