Optical cavity controlled fluorescent photovoltaic cell

摘要

A photovoltaic cell comprising top (5) and bottom (8) electrodes and a photosensitive material (6, 7, 9) with a high quantum yield fluorescence between 0.3 and 1 is provided. The top electrode is of a semi-transparent material adapted to form an open optical cavity with a bottom electrode. The cavity controls the fluorescence of the photosensitive material.
