This technology uses an ultra-thin oxide layer and a polycrystalline silicon layer as a novel passivation structure at rear side of the cell, and can be easily industrialized by upgrading the existing PERC production line. The key technology is the films formation of ultra-thin oxide and polysilicon by using low-pressure chemical vapor deposition (LPCVD) technology instead of expensive solutions, such as plasma enhanced chemical vapor deposition (PECVD) or reactive plasma deposition (RPD). At present, the open circuit voltage of the cell exceeds 700 mV, and the efficiency is up to 23.5％, which is one of the most competitive commercial high-efficiency solar cells.
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.
