<p>One embodiment relates to a dopant material for manufacturing solar cells. The dopant material includes a primary carrier and a dopant system. The primary carrier is a solid at a lower temperature, a liquid at an elevated temperature, and decomposes at a third temperature higher than the elevated temperature. The dopant material is dispensible in a controlled manner at the elevated temperature to a defined area of a silicon substrate at the lower temperature. The dopant system includes a dopant carrier and dopant source. The dopant source is stable at the third temperature. Other embodiments, aspects and features are also disclosed.</p> |
