A radioactive waste acid is recycled. The waste acid is a fluoboric waste acid. The waste acid contains a lot of oxides and radioactive nuclei. The waste fluoboric acid is processed to obtain a purified fluoboric acid. The amount of radioactive nuclei is greatly reduced. Thus, the present invention has a simple procedure with low cost and reduced power consumption.

Method of recycling radioactive waste acid

The present invention is a photosensitized electrode which absorbs sunlight to obtain electron-hole pair. The photosensitized electrode is fabricated with simple procedure and has low cost. The electrode has excellent chemical resist 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.

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 distribution layer of silicon quantum dots are fabricated. After the layer is exposed to sun light for a while, the layer absorbs energy and produces pairs of electron and hole. By limiting the movement of the electrons and their moving directions through the structure obtained, the efficiency of an optoelectronic conversion is enhanced.
