| Sumario: | <div> In this work we have synthesized and characterized four indoline-based small organic molecules</div> <div> for their use as electron donor moiety in bulk-heterojunction solution processed</div> <div> organic solar cells combined with PC70BM as electron acceptor. Our results show a wide</div> <div> range of light to energy efficiencies from 0.8% to 3.5% under standard measurement conditions.</div> <div> An initial analysis suggests that the main limitation is the device photocurrent due to</div> <div> the device film thickness. Yet, charge transfer dynamics were studied to correlate charge</div> <div> loss mechanisms to p-bridge structural variations and, moreover, mobility measurements</div> <div> were also carried out to fully explain these device limitations.</div> |
