Event details

Organic electronics now supports a rapidly growing industry, including organic light-emitting diode, OLED, displays as used in cell phone displays and up-market TVs.  This has been enabled both by successful engineering of materials and devices, and also, through the design of new device architectures that allow control of electron spin.  This is a rapidly moving field, and some recent advances in the basic semiconductor science are likely to enable new applications.

This meeting will focus on the role of the spin state of the bound electron-hole pairs (excitons) that provide light emission in LEDs or separate to give free charge in solar cells.  It is centred on two recent developments.  Using materials engineered to reduce the spin exchange energy, spin triplet excitons can be harnessed for efficient light generation in LEDs.  Conversely, large exchange energies can allow splitting of singlet excitons to pairs of spin-entangled triplet excitons that can be harnessed in solar cell architectures that may exceed the single-junction Shockley-Queisser limit.
