INKS FOR SOLAR CELL INVERTED STRUCTURES

摘要

Compositions and devices comprising at least one conjugated polymer and at least one fluorosurfactant, providing improved wettability. Compositions can be applied to substrates and used in HTL layers in organic electronic devices such as inverted photovoltaic devices. The conjugated polymer can be a polythiophene. The fluorosurfactant can be a perfluorobutane sulfonate fluorosurfactant. Improved methods of making and using the HTL ink composition are provided.
