Many researchers have tried to achieve flexible solar cells, organic light emitting diodes, flexible displays, e-paper, thin-film transistors and so on. Especially flexible solar cells are getting mass appeal. To achieve the flexible solar cells, however, many factors should be considered like stability, sealing problem, efficiency, processibility. Perovskite solid state solar cells are perfect device which could fulfill these requirements. Perovskite have been used in nanostructured solar cells as the sensitizer as well as hole transporter. It cna prepared in easy way. Besides, it showed efficient electron and hole transport ability. We employed the ITO/PEN/TiOx/Al2O3/spiro-OMeTAD use as a hole transporting material. Flexible solid state solar cell showed excellent stable efficiency when they bended. In this report, we assembled perovskite solar cells on the flexible substrate and it showed bright future of the flexible solar cells. |
