Method for synthesizing polyamic acid for manufacturing flexible amorphous silicon solar cell |
摘要 |
The present method provides a method for preparing the PI varnish which has the steps of: 1) preparing a mixed solution of 60-100% by weight aprotic solvent, and 0-40% by weight aromatic solvent; 2) adding into the mixed solution in a mole ratio of 1:9 two aromatic diamines; and 3) further adding in the mixed solution in a mole ratio of 1:5 two aromatic dianhydrides. Such PI has a suitable thermal expansion coefficient and characteristics different form those of the PI currently in use.
