The back surface of solar cell is passivated by atomic-layer-deposited Al2O3 to enhance open-circuit voltage and short-circuit current. The back side contacts are formed by laser-opening technology and the Back Surface Field could be formed locally. This technology could increase efficiency 0.5~1％, and the maximum efficiency could up to 20.8％.
Responsibilities include the formulation of energy policies and regulations; forecasting, planning, and promoting energy supply and demand; reviewing matters related to energy development, production, storage, conversion, distribution, sales, and utilization; proposing energy tariff schemes and reviewing pricing mechanisms; granting permits, registration, management, guidance, and supervision of energy-related enterprises; registration and oversight of certified energy professionals; establishment and management of energy data systems; promotion of energy conservation measures, technical services, and public awareness initiatives; research, development, and dissemination of new energy, renewable energy, and energy-saving technologies; coordination and cooperation in international energy affairs; and other matters related to energy administration.
