Energy Transfer towards Engineered Organic Dyes that Prevent Charge Carrier Trapping (A04)

• Subject Area: Experimental Condensed Matter Physics ; Polymer Materials
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 465145163

For efficient energy transfer from a host to a sensitizer to occur, sensitizers have by definition a smaller bandgap as compared to the host. With regard to charge transport in the host, these sensitizers will therefore act as defects that will severely trap charge carriers. In this project a solution is proposed where energy transfer from host to sensitizer takes place without the negative contribution of additional charge trapping. The difference in characteristic distance between energy transfer and trapping will be utilized to selectively suppress trapping by organic dyes and nanodiamonds.
