Photovoltaic Effect
Photovoltaic cells have been successful in the field of clean energy and are now an important means of harvesting clean energy. The tribovoltaic effect is similar to the photovoltaic effect, the only difference is that the tribovoltaic cell converts mechanical energy into electrical energy, instead of light energy to electric energy.

8.7: Diodes, LEDs and Solar Cells
Diodes are semiconductor devices that allow current to flow in only one direction. Diodes act as rectifiers in electronic circuits, and also as efficient light emitters (in LEDs) and solar cells (in photovoltaics). The basic structure of a diode is a junction between a p-type and an n-type semiconductor, called a p-n junction.

The first optimization step consisted in varying the volume percentage ratios of the two ionic liquids. As reported in Table 1 (see also Figure S.1 of the Appendix A for the J-V curves), the best photovoltaic performance was obtained with a 50/50 vol% ionic liquid ratio. This result was due to the considerable increase of the photocurrent density, …
