Title: Growth of high-quality Si ingots for solar cells using the dendritic cast method

Speaker: Kazuo Nakajima

Inviter: Academician Deren Yang

Abstract:

• Motivation to develop the dendritic cast method

• Growth and behavior of dendrite crystals using the in-situ observation system

• Ingot growth controlled by dendrite crystals grown along the bottom of a crucible

• Effect of angle between dendrite crystals with several orientation

• Control of arrangement of dendrite crystals

• Generation of dislocations

• Quality and solar-cell performance of Si ingots using the dendritic cast method

• Pilot furnace for manufacturing industrial scale ingots

• Keypoints for improvement and impact on development of seed-assisted cast methods
