二面要求做个research关于solar module，可这句话实在没搞懂什么意思。。。When come to solar cell interconnection, zoom in and study the details of various interconnection techniques. Elaborate more on the different heating techniques and working principle used in this market, like IR heating, magnetic induction heating, hot-air, laser heating。是指在连接solar cells时有很多种加热融化焊料的方式？？？可没找到啊。。。。
没找到最合适的版面，只能发职业版了，求太阳能电池行业的大神给指点指点~~~~
