Redox “B”ees : Rational design of a new series of boron‐functionalized Ni III /Ni IV –bis(dicarbollide) clusters results in a family of robust and tunable redox shuttles (see diagram; EDG and EWG denote electron‐donating and ‐withdrawing groups, respectively). This offers a means to rationally control the redox properties in dye‐sensitized solar cells (DSCs), leading to exceptionally high open‐circuit voltages.
