Abstract

The invention provides a polymer / inorganic nano-crystal hybrid solar cell and a manufacture method thereof. P type inorganic nano-crystal cuprous oxide is induced to be taken as a cavity-collecting layer. The cuprous oxide nano-crystal improves ITO surface work function, enhances open circuit voltage, and improves the energy conversion efficiency of the solar cell. Compared with the cell which takes the traditional poly (3, 4-ring dioxide ethylthiophene): polystyrene sulfonate as a cavity transportation layer, the cell which takes the cuprous oxide as the cavity-collecting layer improves the open circuit voltage by 32.5%, short-circuit current by 49% and energy conversion efficiency by 171%; and compared with the cell which not use the cavity transportation layer, the device which takes the cuprous oxide as the cavity-collecting layer improves the open circuit voltage by 55.9%, short-circuit current by 57.2% and energy conversion efficiency by 222%.

Description

technical field [0001] The invention relates to a polymer / inorganic nano crystal hybrid solar cell and a preparation method thereof. Background technique [0002] Polymer / inorganic nanocrystalline hybrid solar cells using conjugated polymers as electron donors and inorganic semiconductor nanocrystals as electron acceptors combine the advantages of solution processing of organic semiconductor materials and high carrier mobility of inorganic semiconductors. research hotspots in this field. Zinc oxide (ZnO) is an environmentally friendly material with high electron mobility and simple preparation methods, which make ZnO have broad application prospects in polymer / inorganic nanocrystalline hybrid solar cells. In 2004, J. Janssen used the blend of zinc oxide nanoparticles and [2-methoxy-5-(3,7-dimethyloctyloxy)-p-styrenevinylidene] (MDMO-PPV) for the first time ( Adv.Mater.2004, 16, 1009-1013) structure heterojunction hybrid solar cells, at 100mW / cm 2 The conversion efficiency...
