Overview of Organic Photovoltaics
Organic photovoltaics — Aqueous-based fabrication

First, it is important to present—or review—the fundamentals of the physical mechanisms underlying organic photovoltaics. To understand how an organic solar cell works, we can break it down into its various components (see Figure 1 a): the core of such a device is its active layer, sandwiched between transport layers (for holes and electrons), which are themselves in contact with electrodes (cathode and anode). These layers share a common goal—the generation of an electric current—but each...
