Effect of Rheological Property of Silver Conductive Paste on
Electrical Property of Si Solar Cells
- Received Date:
Abstract: Different silver conductive pastes were prepared and applied in solar cell. Their rheological properties were adjusted by changing ethyl-cellulose contents in the organic vehicle. With the measurement of rheological properties of silver conductive pastes and grid morphologies as well as electrical properties of the cells, it was found that rheological properties of silver conductive pastes affected the electrical properties of the cells. When the ethylcellulose in the organic vehicle was as high as 6%, the paste had high viscosity in low shear rate and low viscosity in high shear rate, whose frontal electrodes had slicker fringe, higher height and smaller width, while the cells had better electrical properties with high filled factor(FF) and conversion efficiency(η).
