FIG. 1.

(a) Chemical structures of the used organic materials, a schematic diagram of the photovoltaic device structure, and the current density–voltage curves in dark (dash dot line) and under AM1.5G illumination (solid line) of the photovoltaic device with the structure . (b) Dark current (dash dot line) and photocurrent (solid line) density–voltage curves of the photovoltaic device with the same structure after heat treatment at in a glove box under nitrogen environment. The inset diagram shows the calculation of the series resistance of the heated device from the linear part of the dark curve.
