photovoltaic power generation

solar cells is that the semiconductor absorbs photons and converts them into photogenerated carriers and transmits them to the electrode, thereby generating photovoltage and photocurrent. Therefore, the effective extraction and transport of photogenerated carriers before reaching the electrode is very important to the conversion efficiency of solar cells.

waste gas waste water treatment

Waste gas wastewater environmental protection engineering program design needs to consider the industrial production process and chemical principles, combined with the existing environmental protection laws and regulations, the use of advanced technical means and equipment, design for a variety of different enterprises waste gas wastewater environmental protection engineering program.

artificial diamond

artificial diamond is a synthetic diamond made by cutting real diamond into thin slices, polishing, fixing, and polishing. Then hydrogen and methane are injected under high temperature and high pressure to increase its volume ten times. Finally, it is cut and polished to form a shining artificial diamond.
