作者展示了并五苯/C60异质结有机太阳能电池，利用MoO 3掺杂的并五苯薄膜作为界面层在阳极和并五苯和C60之间的多电荷分离层，分别。与参考器件相比，短路电流密度和开路电压同时提高，导致功率转换效率从0.97%提高到2.29%。通过吸收光谱测量、表面形貌分析以及空穴主导型器件阳极侧的界面评价，揭示了MoO 3掺杂并五苯薄膜在OSC中的作用。
The authors demonstrate a pentacene/C60 heterojunction organic solar cell utilizing MoO3-doped pentacene thin films as an interfacial layer at anode and a multicharge-separation layer between pentacene and C60, respectively. The short-circuit current density and the open-circuit voltage were improved simultaneously compared with the reference device, resulting in an improvement in power conversion efficiency from 0.97% to 2.29%. Absorption spectra measurement, surface morphology analysis, and interfacial evaluation at anode side in the hole-dominant devices were carried out to reveal the functions of MoO3-doped pentacene films in OSCs.
