The Role of Driving Energy and Delocalised States for Charge Separation in Organic Semiconductors
Artem A. Bakulin, Akshay Rao, Vlad G. Pavelyev +6
The electron-hole pair created via photon absorption in organic photoconversion systems must overcome the Coulomb attraction to achieve long-range charge separation. We show that t…
Charge-Transfer State Dynamics Following Hole and Electron Transfer in Organic Photovoltaic Devices
Artem A. Bakulin, Stoichko D. Dimitrov, Akshay Rao +7
The formation of bound electron-hole pairs, also called charge-transfer (CT) states, in organic-based photovoltaic devices is one of the dominant loss mechanisms hindering performa…
Charge Trapping Dynamics in PbS Colloidal Quantum Dot Photovoltaic Devices
Artem A. Bakulin, Stefanie Neutzner, Huib J. Bakker +3
The efficiency of solution-processed colloidal quantum dot (QD) based solar cells is limited by poor charge transport in the active layer of the device, which originates from multi…
