Abstract
Wurtzite.type ZnO nanocrystals are synthesized by simple technology in low temperature and are characterized bv HRTEM，XRD and PL technology.Hybrid organic/inorganic bulk heteroiunction solar cells with a structure of IT0/PE. DOT：PSS/ZnO：MDMO-PPV/AI are fabricated utilizing ZnO nanocrystals and polyl 2-methoxy一5.(3’，7’.dimethyloctyloxy)- 1，4.phenylenevinylene l(MDMO.PPV).As a comparison，pure organic solar ceils with a structure of ITO/PEDOT：PSS/MD. MO.PPV/AI are fabricated.The^V curves show that the energy conversion efficiency can be improved about 550 times by addition of ZnO nanocrystals.PL experimental results indicate that the reason might be higher possibility of charges separation by addition of ZnO nanocrystals with high electron affinity.Another possible reason which caused higher photovoltaic (PV)performance is higher electron mobilities in ZnO-polymer PV devices compared with pure organic solar ceils.In addi. tion，the reasons of lower photovoltaic performance of the kinds of solar cells than conventional solar eells are analyzed。and possible solutions are proposed. -
