The problem of cooling the upgrading of China's photovoltaic manufacturing technology needs to be solved urgently

China's photovoltaic investment is concentrated in the construction of photovoltaic power plants, and the transformation and upgrading of key technologies in the manufacturing industry is cold, and this problem needs to be solved
urgently.
There is a view that the development of photovoltaic manufacturing technology in China should be promoted by the national level, or the model of joint development of enterprises is better
.

Wang Bohua, secretary-general of the China Photovoltaic Industry Association, pointed out that after the domestic photovoltaic market has become larger, it is urgent to need technical support for further development
.
Under the premise of the return of manufacturing, European and American companies focus on the improvement
of photovoltaic manufacturing technology through acquisition of related industries or investment research.
For example, SolarCity previously announced the acquisition of Cyon Power and the construction of a 1GW photovoltaic module plant in New York, precisely because of the latter's composite silicon-based thin-film tunnel heterojunction technology
.

However, Hong Wei, executive vice president of the China Energy Economics Research Institute, believes that the current processing technology and cell conversion rate of China's photovoltaic industry are not inferior to foreign countries
.
It may be slightly backward in the slicing link of precision processing, but in other aspects, whether it is polysilicon purification or high-end equipment processing and production level, it is not lost to foreign countries
at all.

In addition, Hongwei also pointed out that after the industry downturn from 2010 to 2013, China's photovoltaic industry has gradually changed
from price to performance.
It may not be like Huawei, which invests 14.
2% of its revenue in research and development, but from the perspective of the industry background, domestic companies will focus on scientific research and technology
.

In terms of continuous investment in technology research and development, many domestic companies do not have enough energy and personnel to operate, even if they have invested, after the technical personnel are "dug", the technology is basically taken away for free
.
Therefore, in his view, the development of photovoltaic manufacturing technology should be promoted by the national level, or it is better to take the joint development of enterprises as a model
.
To promote research and development without relying on the national engineering technology research center under a large company, or the joint development of several large enterprises with scale and strength in the industry, multiple technical routes are carried out at the same time, competing with each other, or will be the solution to concentrate on the technological upgrading of the photovoltaic industry
