Emerging solar cells are attracting attention as a new alternative energy source, paying attention to their advantages such as light weight, flexibility and low cost. In recent years, their fields have moved to company which produce real products beyond the school or research institute, further raising the expectation for emerging solar cells. However, compared to conventional solar cells, low efficiency and stability still remain to be solved. In this thesis, I showed the design and fabrication results of tandem structure for fabricating high efficiency organic solar cell by utilizing doping technology of organic semiconductors. In addition, the stability of the quantum dot solar cell device can be greatly improved by using a small molecular thin film that is strong against oxygen and moisture. Furthermore, in order to take advantage of the flexibility of emerging solar cells, organic solar cells were fabricated using silver nanowire and graphene as transparent electrodes instead of conventional rigid indium tin oxide (ITO), and it was shown that ITO can be effectively replaced. These results are expected to further develop in the near future and will soon be able to see emerging solar cells around us, easily.
