Recent trend of solar cells is transparent solar cells. Organic solar cells (OSCs) have been studied for transparent solar cells, because of its printable and transparent characteristics. However, it’s still not enough efficient and transparent for commercialization. The main reason for insufficient transmittance is active layer’s visible area absorption and opaque electrodes. To solve this problem, thin metal electrode method is introduced to enhance the transmittance. However, as the transmittance is increased, the conductivity is decreased simultaneously. Consequently, the power conversion efficiency (PCE) is also decreased. The hybrid hole transporting layers with composite materials can help thin electrode growth to maintain high conductivity. In this study, we fabricated Inverted structured OSCs with hybrid hole transporting layers with composite materials. As a result, the optical and electrical properties of OSCs with hybrid hole transporting layers have enhanced. |
