CoSe2纳米材料在染料敏化太阳能电池中应用研究
Application research of CoSe2nanomaterials in dye-sensitized solar cells
摘要
Abstract
In order to further explore the electrocatalytic performance of cobalt selenide counter electrodes (CEs), cobalt diselenide (CoSe2) CEs were constructed by using sodium hydrogen selenide as selenide source, cobalt chloride hexahydrate as cobalt source. So, CoSe2nanomaterials were synthesized by a hydrothermal method at firstly. CoSe2CEs were fabricated by a spray method. Then the electrocatalytic activity of CoSe2CEs was systematically investigated. And the effect of CoSe2CEs on photoelectric performance of dye-sensitized solar cells (DSCs) was also systematically investigated. The results from structure morphology show that CoSe2nanomaterials with pure phase have an amorphous structure composed of numerous nanoparticles. In addition, CoSe2CEs exhibit high electrocatalytic activity by electrochemical performance test. Furthermore, the power conversion efficiency of the DSC with CoSe2CE as high as 5.77% is obtained (short-circuit current density of 13.88×10-3A·cm-2, open-circuit voltage of 0.65 V, fill factor of 0.64), which is similar to that of the DSC with Pt CE (power conversion efficiency of 5.99%, short-circuit current density of 14.62×10-3A·cm-2, open-circuit voltage of 0.64 V, fill factor of 0.64).关键词
