Organic solar cells (OSCs) have been studied prospective energy converting devices for their low cost and various materials application. However, OSCs have some disadvantages such as limited absorption properties, low carrier mobility and energy level mismatch between electrode and active layer. MoO3, good performance as hole transporting layer(HTL), needs essential deposit process in inverted solar cell. Although using solution process with PEDOT:PSS can reduce process cost, its acidic property can decrease stability of device. This problem can be overcome by introducing organic-inorganic hybrid HTL. To introduce this organic-inorganic hybrid HTL, the energy level between active layer and electrode can be modified and carrier mobility can be increased. In this study, we fabricated inverted structured OSCs with organic-inorganic hybrid HTL via solution process. As a result the stability and performance of OSCs with organic-inorganic hybrid HTL were enhanced. |
