Sanan Optoelectronics limit even pull three bodies longing GaAs solar cells

Reserves GaAs solar cell project

After the suspension on Zhou Sanan Optoelectronics, United Securities released a report revealed that the company is planning to refinance the information; in that report, to raise funds to invest in addition to this the company announced Tianjin base, there GaAs solar cells.

Although the company has not announced the program will be included in the equity investment and the latter range, but yesterday Yuexiong Wei told the "Daily Economic News" reporter, said the business is expected in the future become another growth point.

GaAs concentrator solar cell is referred to the third generation solar cells, mainly by the GaAs solar cell chip, high condensing lens and the sunlight tracking components. Has been widely known to the market with silicon solar cells, the photoelectric conversion efficiency is 95% of the theoretical limit, which is only about 17% - the same size, 500-fold concentration efficiency GaAs solar cells, light-emitting efficiency about 1000 times can be improved for use in industrial power plants.

KGI is also optimistic about the three safety photoelectric GaAs solar cells. KGI Securities research report pointed out yesterday, concentrating solar power generation system suitable for large-scale 10MW ~ 100MW power plant system, suitable for light a long time, sunshine, high strength, low water vapor region, while China Qinghai, Tibet, Yunnan, Xinjiang, Sichuan, Gansu and southwestern regions are better.

KGI entire system is expected to cost 2 billion to 2.7 billion, while operating income last year was 2.13 billion yuan.

However, Yuexiong Wei also said, GaAs solar cell panel technology is not yet mature, and is expected to give the company a significant profit real point in time is after 2023. KGI Securities also said that he expected when the conversion efficiency of 35%, concentrating multiple times in 1000, the cost can be reduced to 0.68 yuan per kWh, then have a chance to challenge the traditional tariff levels. Sanan Optoelectronics currently set up in the factory test run condenser system, the conversion rate of about 25%, using 500 times the condenser.

KGI also noted that the three safety photoelectric current GaAs solar cell technology gap with foreign representatives enterprises have not, and are based on 500 times the condenser. Yuexiong Wei also said that the three safety photoelectric technical reserves in this area is good, they are currently only listed company engaged in the development of GaAs solar cells; while in the entire PV system, the battery is the most central parts, and a very high technical threshold also let the first two years of collective domestic enterprises to invest and polysilicon project is unlikely to be repeated this scene.
