Summary: This study investigates recombination loss in dye-sensitized photoelectrochemical solar energy conversion systems using a computational model, finding that while electrolyte-electron reactions are efficient, they do not significantly impact photoanode performance. The chemistry of the solution-phase electrolyte plays a key role in reducing electron losses by cycling electrolyte species to produce I- within the photoanode pores. This functional adaptive response of chemistry may partly explain the success of the redox couple in dye-sensitized solar cells.

Summary: In this study, a post-lithium (Li) treatment on TiO2 films was performed to enhance the optoelectronic features and power conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs). The Li treatment reduced defects and improved the crystallinity of the TiO2 films. DSSCs fabricated using Li-treated TiO2 films as photoanodes showed a performance improvement of approximately 20% and a PCE of 10.5%, compared to the control DSSC with a PCE of 8.7%. The enhanced performance was attributed to improved structural properties, efficient charge transport, and suppression of recombination due to the passivation of trap states.
