An exciting area of solar research is exploring the new materials that will become the next generation of solar cells: more efficient, more powerful and with a longer lifespan. The silicon-based tandem solar cell is widely regarded as a leading contender in the field, and our group works to develop stable, environmentally friendly, and abundant new materials on silicon to achieve these aims.
We have established a computational modelling capability to evaluate the electrical and optical properties of new PV materials. Our synthesis approaches for simulating promising PV materials have been developed using various chemical and physical methods. Leveraging our advanced characterization technologies, material quality improvement and device structure optimization are both under investigation in order to achieve high performance new PV materials for the next-generation silicon-based tandem solar cells, which will be made of abundant and non-toxic materials.
