This chapter analyses the photoelectron movement and storing energy characteristic in the process making hydrogen. The change of solar energy chiefly has two kinds of forms: solar energy is changed into the electric energy using the solar cell and solar energy is changed to thermal energy using the solar energy collector. The changing efficiency of these methods is low and storing the energy is also difficult. The influence of time, season, weather, and region is very notable. The function of high polymer material as photoactive preparation and quenching preparation can decompose water into hydrogen and oxygen in the photoelectron movement reaction, so as to change solar energy into the chemical energy. This method uses chemical way to store energy. On oxidizing efficiency and difficulty, the oxidizing reaction of four electrons shift is better than single electron.
