New diodes drive green energy technology

The development needs of green energy technology
Environmental policies promote the development of new energy
Global environmental policies are accelerating the popularization of green energy technologies. For example, the Paris Climate Agreement requires countries to reduce carbon emissions, which has led to an explosive growth in the application of renewable energy sources such as solar and wind power.
