Silver nanowire flexible ITO-free polymer solar cells

摘要

Flexible ITO-lree P3HT:PC61BM solar cells with spin-coated silver nanowire transparent electrode are demonstrated. For conventional structure type of solar cells, the power conversion efficiency (PCE) of devices based on silver nanowire can reach around 2.29%. As for inverted structure type, the PCE of devices can reach 3.39%. The conventional and inverted flexible ITO based P3HT:PC61BM solar cells are also fabricated as a reference for comparison. For both type of solar cells, the PCE of ITO-free devices are very close to those of ITO based polymer solar cell.
