Organic solar cells possess multiple desirable traits, such as low cost, flexibility, and semitransparency, which opens up potential avenues unavailable to other technologies, a prime example of this being window applications. For specific application, delicate balance between the transmission light through device power conversion efficiency (PCE), dependent on amount absorbed, must be optimized. Here, we report high-efficiency semitransparent based novel fullerene-free material system. Using an active layer system PBDB-T:ITIC, optimized devices exhibited PCEs exceeding 7% while also achieving average visible transmittance (AVT) 25%. The concurrent demonstration high with AVT 25% represents notable step forward for organic cells. Additionally, influence thickness color rendering properties these was studied. Optimization can lead cells, well ability display image accurately.
