·ÒëÈçÏ£º 1.In the process of preparing the back membrane of solar cell , change the type and quality of diisocyanate in the chemical formulation ,and the Preparation Conditions of the sample that is to be tested. 2.Find a chemical formulation and a curing agent better than the exciting ones ,and the best way of using them by testing the peelstrength between back membrane and EVA ,to maximize the value of the peelstrength between back membrane and EVA , and ultimately to improve the property of the solar cell . 3.It is shown by the research that , as the ratio of iso-thio-cyano to hydroxy chaning from 0.8 to 1.2 , the cohesive force between back membrane and EVA decreased gradually ,which means the more the quality of residuary hydroxy ,the stronger the cohesive force between back membrane and EVA. ºÙºÙ£¬Â¥Ö÷£¬ÓÖÊÇÎÒ£¬Ïà¹Ø´Ê»ãÔÚÄãµÄÉÏÒ»Ïà¹ØÖ÷ÌâÖÐÒѾÌṩ£¬ÕâÀï¾Í²»ÔÙÖØ¸´ÁË¡£ ×¢Ò⣺̫ÑôÄÜµç³ØµÄ¡±±³Ä¤¡°µÄÓ¢ÎÄÊÇ¡° back membrane ¡± ![]() [ Last edited by zsw4882535 on 2010-6-17 at 16:31 ] |

ÎÒÓÐÒâ¼û£¡ 1.

A new curing agent better than that in existing formulation and its best service condition were found after testing in various condition, so that the membrane-EVA peel strength was maximized and the performance of solar cell was finally improved. 3. The result showed that back membrane-EVA cohesive force reduced as the ratio of isocyanate to hydroxy varied from 0.8 to 1.2, which means the more the excess quantity of hydroxy, the stronger the cohesive force between back membrane and EVA. |
