Reduction Bending of Thin Crystalline Silicon Solar Cells
Reduction Bending of Thin Crystalline Silicon Solar Cells
摘要
Abstract
Reported are the results of reduction the bending of thin crystalline silicon solar cells after printing and sintering of back electrode by changing the back electrode paste and adjusting the screen printing parameters without effecting the electrical properties of the cell. Theory and experiments showed that the bending of the cell is changed with its thickness of substrate, the thinner cell, the more serious bending. The bending of the cell is decreased with the thickness decrease of the back contact paste. The substrate with the thickness of 190μm printing with sheet aluminum paste shows a relatively lower bend compared with that of the substrate printing with ordinary aluminum paste, and the minimum bend is 0.55 mm which is reduced by 52%.
