The present invention is a photosensitized electrode which absorbs sun light to obtain pairs of separated electron and hole. The photosensitized electrode is fabricated with simple procedure and has low cost. The electrode has excellent chemical resistance and is fitted to be applied in a solar cell device with enhanced sun-light absorbing ability. The present invention can be applied in an optoelectronic device or a hydrogen generator device too.

A sun-tracking apparatus has a photo sensor. The apparatus can precisely track the sun. The apparatus uses two tracking modes for different conditions and weathers. By doing so, a maximum power efficiency is obtained.

Hybrid mode sun-tracking apparatus having photo sensor

A structure of an optical switch makes the optical switch capable of receiving broadband signals. And the manufacturing procedure is simplified.
