| Outline of Final Research Achievements |
Size-quantized semiconductor nanocrystals, so-called quantum dots (QDs), have attracted much attention for the application of light energy conversion systems. For the purpose of solar cell application, it is expected that the control of their arrangement of QDs, that is stuck structure of QDs, will improve the energy conversion efficiency of the cells because a preferable energy gradient can be obtained to drive the photogenerated electrons in semiconductor QDs array toward the collecting electrode.
In this study, I tried to achieve that by the development of ZnSe-AgInSe2 solid solution QDs having widely-controllable-electronic-energy structure. Thus-prepared QDs were assembled onto electrode using dip-coating technique and investigated the electronic energy structures-related photocurrent generation.
