본문내용
WHAT IS A SOLAR CELL?
Devices that convert solar energy to electric energy.
WHAT IS PHOTO ELECTRIC EFFECT?
The photoelectric effect is a phenomenon in which electrons are emitted from matter as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength, such as visible or ultraviolet light
Absorption and generation of exciton
Dissociation and separation
Transport and collection
PCBM has a drawback and thus contributed very little to the absorption of solar light.
- using other acceptors which absorbs at longer wavelengths
- stacking solar cells based on materials that absorb in different wavelength region
