中文摘要	efficient charge collection is one of the most important factors to achieve high power conversion efficiency for the bulk-heterojunction solar cells based on polymer blend films. we report enhanced hybrid polymer solar cells based on blends of a semiconducting polymer poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene] (meh-ppv) as electron donor and crystalline n-type zno nanoparticle as electron acceptor by using p-type semiconducting cu2o nanocrystal as an anode buffer layer between the indium tin oxide (ito) anode and the meh-ppv:zno blend layer. the p-type cu2o nanocrystals of 30-40 nm diameter dispersed on ito anode surface percolate into the meh-ppv:zno blend layer serving as hole collection antenna to efficiently collect holes. the results show that the charge recombination in the meh-ppv:zno blend layer resulting from low charge mobility of meh-ppv is effectively restrained via hole-transport bypass of cu2o nanocrystals. compared to the control device with poly(ethylenedioxythiophene):poly(styrenesulfonate) (pedot:pss) as a flat anode buffer layer, the short-circuit current increases 45% for the device with cu2o nanocrystal as an anode buffer layer. moreover, the lower ionization potential of cu2o nanocrystal renders the device a high open-circuit voltage compared to the device with pedot:pss as an anode buffer layer. the optimal device with cu2o nanocrystal as an anode buffer layer shows a power conversion efficiency of 2.0%, a 132% increase compared to the device with pedot:pss as an anode buffer layer.
