摘要

以紫外臭氧处理超薄Ag复合MoO

或PEDOT：PSS修饰ITO电极的高效柔性有机太阳能电池。通过优化紫外臭氧处理Ag薄膜的时间，提高了以P3HT：PCBM为有源层的器件的功率转换效率，从1.68%（未经过紫外臭氧处理）提高到2.57%（紫外臭氧处理Ag 1 min）。提高的原因推测是紫外臭氧处理形成了AgO

薄膜，提高了电荷提取并使器件具有高光学透明度、低串联电阻和优异的表面功函数等一些性能。并且，紫外臭氧处理Ag薄膜与MoO

或者PEDOT：PSS复合修饰ITO的器件效率分别得到提高，Ag薄膜与MoO

复合修饰ITO的器件效率从2.02%（PET/ITO/MoO

）提高到2.97%（PET/ITO/AgO

/MoO

），Ag薄膜与PEDOT：PSS复合修饰ITO的器件效率从2.01%（PET/ITO/PEDOT：PSS）提高到2.93%（PET/ITO/AgO

/PEDOT：PSS）。此外，以PBDTTT-EFT：PC

BM为有源层的柔性聚合物太阳能电池效率可达6.21%。基于ITO的柔性光电器件效率的提高主要归于ITO被Ag/PEDOT：PSS或Ag/MoO

修饰后功函数的提高。

Abstract

Highly efficient heterojunction polymer solar cells based on ITO flexible electrode were developed with an UV-ozone-treated ultrathin silver interlayer combined with MoO

/PEDOT:PSS as modification materials. By optimizing UV-ozone-treated time of silver thin films

it could improve the power conversion efficiency (PCE) of the device based on the blend of poly(3-hexylthiophene) (P3HT):[6

6]-phenyl C

-butyric acidmethyl ester (PC

BM) from 1.68% (without UV-ozone treatment) to 2.57% (Ag with 1 min UV-ozone treatment)

which might be an AgO

layer formation that improves hole extraction and several promising characteristics

including high optical transparency

low sheet resistance and superior surface work function. Meanwhile

the devices with UV-ozone treated thin Ag layer together with MoO

or PEDOT:PSS improves PCEs from 2.02% for the device with PET/ITO/MoO

to 2.97% for the device with PET/ITO/AgO

/MoO

and from 2.01% to 2.93% for device with PEDOT:PSS. In addition

the PCE of 6.21% of the flexible polymer solar cells based on poly[4

8-bis(5-(2-ethylhexyl)thiophen-2-yl)-benzo[1

2-b;4

5-b'] dithiophene-2

6-diyl-alt-(4-(2-ethylhe-xyl)-3-fluorothieno[3

4-b]

thiophene-)-2-carboxylate-2-6-diyl(PBDTTT-EFT):[6

6]-phenyl C

-butyric acid methyl ester (PC

BM) as an photoactive layer was obtained. The efficiency improvement of the flexible OPV based on ITO is due to the increase of the work function of ITO by ITO/Ag/PEDOT:PSS or MoO

composition.
