PTEBS (CAS number 744198-90-1), sodium poly[2-(3-thienyl)-ethoxy-4-butylsulfonate], is a water soluble, environmentally friendly conjugated polythiophene and it has proven to be effective for enhancing the performance of hybrid solar cells.

Absorption spectrum of the PTEBS can be tuned by acid doping. When PTEBS is acidified, self-doping happens, and it leads to optical and infrared absorption changes with increased conductivity. These new absorption bands in return could improve efficiencies for photovoltaic device performance.

PTEBS can also be employed as a cathode interfacial material for perovskite solar cells. Ultrathin coating of PTEBs can lead to effective energy level aligning with improved film morphology. With a better ohmic contact between the perovskite layer and the cathode, device charge extraction and transport can be enhanced.
