Abstract
Polymer light-emitting electrochemical cells are demonstrated with circular driving electrodes and ring-shaped bipolar electrodes. The microfabricated electrode patterns enable the formation of seven to forty-nine concentric light-emitting rings across a large gap between the circular driving electrodes. Cells with BPEs exhibit vastly faster cell activation and much greater peak cell current. Cell activation in a PLEC constitutes in situ electrochemical doping and the formation of a light-emitting p–n junction. After junction formation, the PLEC can be discharged to produce an open-circuit voltage ( V OC ). Herein, we demonstrate that the discharging open-circuit voltage is directly proportional to the number of BPEs introduced and the number of junctions formed. A 49-junction cell exhibits a record-high discharging V OC of 98.5 V. Moreover, the activated cells can be frozen and operated as photovoltaic cells when exposed to light. Once again, a linear relation is observed between the photovoltaic V OC and the number of activated junctions. The 49-junction cell exhibits a photovoltaic V OC of 47.5 V, which increases to 64 V after partial dedoping to remove microshorts. These record-high V OC s are contributed by the multiple p–n junctions formed in series across the BPEs. This study showcases the versatility of polymer light-emitting electrochemical cells in both device configurations and functionalities. The planar cell electrode pattern is highly scalable. This device configuration offers potential for an all-in-one device that can generate, store, and output electrical energy with variable voltage, eliminating the need for additional wiring.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
