Longi Gains An Efficiency Of 26.81
LONGi Power is celebrating its 26.81% efficiency for HJT solar cells, which represents a significant milestone in the company’s efforts to develop low-cost and high-performance silicon solar cell technology.
A solar cell is a device that converts sunlight into electricity. The efficiency of a solar cell is the ratio of the amount of usable energy from the sun that it converts to electricity and the amount of electrical power converted.
The company said it had achieved the record by using its new manufacturing process, which is said to be twice as efficient as other manufacturing methods. This breakthrough, as confirmed by the Institute for Solar Energy Research in Hamelin (ISFH) was achieved by combining state-of-the-art technology with new production processes at LONGi’s advanced plant in Gansu Province, China. The company has been working on HJT since 2000, testing a variety of materials and processing technologies.
The founder and president of LONGi, Li Zhenguo emphasized that the company’s theme still remains to improve the efficiency and the cost of energy through the development of the photovoltaic industry.
He noted that for even a substantial efficiency of about 0.01 to be achieved, it requires a lot of dedication and commitment from the company. He said that nearly 95% of the photovoltaic market uses crystalline silicon cells, which are very essential in the industry. Previously, LONGi had announced an efficiency of 25.547 % in March 2022.
The active layer of a conventional silicon solar cell consists of a layer of n-type silicon doped with phosphorus, which absorbs photons and converts them into free electrons (positive charges). These free electrons flow through a p-n junction to the electrode where they are collected as electrical current.
An alternative material used in recent years is an HJT cell, which uses gallium arsenide instead of silicon. This material can be deposited in micron or nanoscale sizes to maximize its absorption coefficient at specific wavelengths, allowing it to convert more light into electricity than conventional silicon solar cells.
With more innovations in the solar system, let’s wait and see what LONGi has in store for its consumers. It surely won’t disappoint!
