Outline of Final Research Achievements

The purpose of this research is to develop organic solar cells and perovskite solar cells using graphene and graphene oxide (GO), which are the nano-carbon materials, as anode electrodes. First, we tried to used GO layer for a hole transport material (HTM) in substitution for conductive polymer. We fabricated the perovskite solar cells and found that GO layer act as an efficient HTM. We also found that variability of solar cell performances using GO was smaller than that using conductive polymer. It is expected that solar cells using all-nanocarbon anode made from graphene transparent electrode and graphene oxide HTM in the near future.
