Investigation of P Type Emitters for Future Generation Photovoltaics

Continued improvements in the cost-competitiveness of solar cells require increases in their efficiency through the use of improved materials. N type silicon is known to be a superior material for solar cell applications which offers higher conversion efficiencies compared to the almost exclusively used p type silicon. A prerequisite to widespread commercial application of n type silicon is the realization of high quality emitter structures in this material. This project will comprehensively investigate such emitters, and then use the understanding gained to develop and optimise fabrication processes to enable their implementation. This will result in higher efficiency photovoltaic devices.
