(HJT-101型立式双面热丝CVD/Vertical Bifacial HWCVD (model HJT-101)

一、概况
Outline
本设备由南昌大学光伏研究院与帕萨电子装备有限公司联合研制。用于非晶硅/晶体硅异质结(HJT)太阳电池研发与制造,制备本征及掺杂非晶硅薄膜,同时作为150MW产线设备开发雏形。
(发明专利:ZL201821326540.9,ZL201821326561.0,201821331132.2)
Jointly developed by Indtitute of Photovoltaics, Nanchang University (IPV) and DG Plasma, for research and pilot-scale fabrication of full size a-Si/c-Si heterojunction (HAC) solar cells, and as a prototype for production line of 150MWp/a scale.
(Patent: ZL201821326540.9,ZL201821326561.0,201821331132.2)



二、主要优势
Major advantages
1、可在不破真空情况下实现硅片双面的i/n、i/p四层薄膜的连续制备;
2、无绕镀问题;
3、特殊设计延长热丝寿命;
4、与现行产线i/n和i/p非晶硅薄膜需分两台装备完成相比,可节省一组unload/load 腔和上下料自动化;
5、产能扩展空间大。
l Bifacial continuous deposition of i/n and i/p a-Si:H films
l Free of round deposition problem
l Prolonged hot wire life through a special design
l Saving a set of unload/load chambers and automation, compared with other  current models, which requires two sets of CVD to perform i/n and i/p a-Si:H films respectively
l Good scalability
