Organic solar cells (OSCs) have been studied because of their low cost and simple manufacture process. However, OSCs have some disadvantages such as unbalanced carrier mobility, low stability resulted from energy level mismatch between electrode and active layer. To solve these issues, many researchers replaced MoO3 to various HTLs materials. Through solution process, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is commonly used as HTLs by its high conductivity and solution processable properties. However, devices introduced PEDOT:PSS still attain lower power conversion efficiency (PCE) and stability than MoO3 deposited devices. Solution processable hybrid HTLs can be modified properties of carrier mobility and energy levels. In this study, we fabricated inverted structured OSCs with hybrid HTLs via solution process. As a result, the stability and performance of OSCs with solution processable hybrid HTLs were enhanced. |
