【摘要】 选择性发射极及快速热扩散是有前景的规模化晶体硅太阳电池生产技术。本文介绍了一种能用于丝网印刷的浆料,即用磷源及高聚物配制成高粘而稳定的磷浆,用于选择性发射极太阳电池正面电极区域的高掺杂用,通过自制丝网印刷涂源及RTP快速扩散后,特性基本满足选择性发射极的要求。更多还原

【Abstract】 Selective emitter and rapid thermal processing are promising techniques for fabricating solar cells in mass production, In this paper, we present a preparation method of a screen printable phosphorous diffusion paste which is made by adding a polymer solution to the phosphorous dopant and form a stable and transparent paste. It can achieve a relatively high dopant concentration under the metal contacts areas after diffusion, and meet the essential needs for the preparation of a selective emitter.更多还原
