characteristics, under AM 1.5 solar spectrum irradiation (, 1 sun), of multilayer devices (ITO / HBL / porous (120 nm) / TPD(4M)-MEH-M3EH-PPV(50 nm) / PEDOT / Au) with or without the PEDOT layer. The inset shows the dark characteristics of the multilayer device with PEDOT (solid line) and without (dash line).
(a) characteristics under A. M. 1.5 conditions (1 sun) for both thick (200 nm porous , 100 nm polymer) and thin (100 nm porous , 50 nm polymer) devices. The inset shows the AM 1.5 power conversion efficiency for devices with different porous layer thicknesses for a constant polymer thickness (100 nm); (b) EQE spectrum of the thin multilayer device (filled squares) and the corresponding absorption spectrum of the polymer (solid line).
Comparison of the performance (AM 1.5) of our devices with that of the best previously reported hybrid / polymer solar cells.
