Dendritic Electrode Formation Via Liquid Overlayers
Electrical structures which interact with light, such as solar cells and optical sensors, generally employ electrodes to collect a generated current (or to apply an external field) however, the electrode designs commonly used suffer from a number of disadvantages. For example, the wide spacing of electrodes in conventional solar cells, necessary to...
