Here, we introduce a molecular co-doping strategy in which a brominated dithieno[3,2-b:2′,3′-d]pyrrole derivative (DTP-OMe-2Br) is incorporated into Spiro-OMeTAD to synergistically combine their advantages. Owing to its planar donor-rich framework and bromine functionalities, DTP-OMe-2Br preferentially localizes at the perovskite/HTL interface, enhancing hole mobility, passivating undercoordinated Pb²⁺ defects, and increasing hydrophobicity without disrupting Spiro’s film-forming properties. As a result, devices achieve a champion PCE of 24.41 %, surpassing the 23.06 % of the pristine Spiro-OMeTAD reference, and retain over 85 % of their initial efficiency after 2500 h in ambient air.

Their low toxicity and high stability endow them with potential medical uses, which hints at the need for CQDs in large quantities. Thus, a sustainable synthesis of CQDs has to be worked out to ensure the minimum use of energy and toxic chemical substances. A ‘top-down’ route to their synthesis involves the disintegration of relatively larger carbon structures like carbon nanotubes, nanodiamonds, and graphite, using energy-intensive processes, such as photoablation, arc discharge, and electrochemical techniques. An alternative to this is a ‘bottom-up’ method, which minimizes energy's utility, and can be achieved through the green synthesis of CQDs, from various plant sources, like herbs and the nightshades (family Solanaceae).
