Silicon Materials

Our research aims to improve the quality of silicon materials used for solar cells, therefore increasing the efficiency and reducing the cost of silicon photovoltaics.

Low-cost silicon materials for solar cells, such as multicrystalline silicon wafers, or solar-grade silicon feedstocks, often contain significant quantities of unwanted impurities. Our research aims to understand the effects of these impurities, and to develop practical ways to reduce their impact, or remove them. There are several classes of important impurities: dopants (such as B, P and Al), which are very difficult to remove during purification; metals (such as Fe, Cr, Ni etc), which can create strong recombination centres; and light elements (such as O, C and N), which may create defects that cause recombination or shunting. Crystal defects such as grain boundaries and dislocations also play an important role, and can interact with the impurities, for example, by acting as preferred sites for precipitation of metals.

Even in prime quality monocrystalline wafers, intrinsic defects such as vacancies and self-interstitials, through their interactions with ever-present light elements such as O and N, can play a critical role in limiting cell performance, especially for high efficiency cell designs that are very sensitive to recombination.
