Power conversion efficiencies of organic photovoltaic cells are approaching conventional solar technologies, with reports of nearly 20% efficiency at the small-cell level. To improve these efficiencies, researchers are investigating ways to better manage how light interacts with the cell through coupling and retention strategies.
When these photons make contact with a PV cell, they transfer their energy to the electrons in the atoms of the cell''s material. These energized electrons break free from their atoms, creating an electric current. This process, known as the photovoltaic effect, is the basis of how solar energy is converted into electricity using PV systems.
