Abstract:
A photoelectric conversion element comprises a solar-energy epitaxial layer, a bond layer and a LED epitaxial layer, which are stacked sequentially. The bond layer has a plurality of holes allowing light to pass. The solar-energy epitaxial layer receives light via the holes and generates electric energy, and an external secondary battery stores the electric energy. When environmental illumination disappears, the LED epitaxial layer is powered by the external secondary battery to emit light. When the photoelectric conversion element of the present invention applies to outdoor traffic signs, advertisement signboards and indicators, they can operate without external power supply.
