Printed organic photovoltaic device with buffer layers
E-mail:
Fully printed organic photovoltaic (OPV) devices were fabricated using slot die coating, electro-spraying, and screen printing technologies. A fundamental study was performed to fabricate the organic photovoltaic device with the functional layers. In order to minimize the decrease of the device performance caused by printing, electron and hole extraction buffers were inserted. The insertion of the ethoxylated polyethylenimine electron extraction buffer layer between the cesium-doped TiO2 layer and active layer helped electron extraction by reducing the interlayer resistance. The insertion of a photo-curable hole extraction buffer layer between the active layer and metal electrode helped to reduce the leakage current. The series resistance decreased and the shunt resistance increased with the insertion of this hole extraction layer. The electron and hole extraction buffer layers improved the device performance of the printed OPV device.
