摘要：首先制备出量子点(QDs)/TiO_2涂料,分别采用丝网印刷法与刀刮法将涂料涂覆于ITO/PET柔性基底上,结果表明刀刮法制备量子点敏化太阳电池(QDSCs)效果更佳,且具有普适性。基于铜片对电极所组装的ZnCuInSe,CdSe和CdSeTe量子点半柔性QDSCs最高效率分别达2.83%,2.46%和1.99%。另外,我们对石墨纸进行表面化学修饰以提高亲水性,再通过简单的连续离子交换吸附法(SILAR)在石墨纸上负载Cu_xS纳米粒子,制备出Cu_xS/GP柔性对电极,进一步组装成全柔性QDSCs,获得了2.13%光电转化效率。
The pastes containing quantum dot(QDs)/TiO2 were first synthesized,and then screen printing and doctor blading were employed for coating the pastes onto ITO/PET flexible substrates.The results show that doctor blading was universal and more effective to obtain high efficiency quantum dot sensitized solar cell(QDSCs).The assembled ZnCuInSe,CdSe and CdSeTe semi-flexible QDSCs obtained high conversion efficiencies of 2.83%,2.46%and 1.99%respectively when brass-based counter electrodes(CEs)were used.Furthermore,surface chemical modification was first carried out on graphite paper(GP)to improve the hydrophilicity,then CuxS nanoparticles were grown on GP via successive ionic layer adsorption and reaction(SILAR).The as-prepared flexible CuxS/GP CEs exhibited satisfactory performance and the assembled fully flexible ZnCuInSe QDSCs obtained high efficiency of 2.13%.
