방법 할 일 당신 이해 그의 많은 새로운 태양광 기술?

Firstly, we classify the new technologies according to four dimensions: efficiency plus cost reduction, pure efficiency, pure cost reduction, and cost reduction but efficiency reduction, with the numerator side of the dosage cost reduction and the denominator side of the dosage cost reduction receiving different levels of attention at different times, The only technologies that can simultaneously improve efficiency and reduce costs are 0BB and copper plating.

Secondly, whether a new technology can have mass production value needs to be compared with other new technologies for comprehensive consideration, such as {{0}}BB plus silver clad copper plus steel plate printing vs laser transfer vs copper plating in metallisation, and needs to be placed in the same time dimension for comparative analysis, such as the same long-term dimension, 0BB plus silver clad copper single W metallisation cost is 0.06 yuan / W, copper plating metallisation cost is also 0.06 yuan / W. W, which in reality does not improve efficiency compared to silver-clad copper, i.e. the main significance of copper plating for HJT is actually a 0.2 percent -0.3 percent efficiency improvement.
