In recent years, researchers have been experimenting with a wide range of solar cell designs in the hope of facilitating their widespread deployment. Organic solar cells based on perovskite materials have been found to exhibit various advantages over conventional solar cell designs based on conventional silicon, including lower costs of fabrication, greater flexibility and tunability.

So far, organic solar cells have achieved a maximum certified power conversion efficiency (PCE) of 19.4%, which is lower than that exhibited by silicon solar cells. A proposed strategy …
