Solar energy, due to its abundance and wide availability, will certainly play an important role in the future energy mix. In our research we explore novel ways of using nanomaterials to convert solar energy.  In particular, we aim to take advantage of the widely tuneable optical and electronic properties of quantum confined materials for energy conversion. We are interested in the preparation, advanced optical characterisation, and application of these materials.

Co-catalyst decorated semiconductor nanocrystals for instance can be used in the photocatalytic generation of solar fuels such hydrogen or carbon dioxide reduction products (methane, methanol etc.). A detailed fundamental understanding of their optical, electronic properties and charge carrier dynamics is important for the design and future applications of these materials. We are also interested in developing non-toxic and earth abundant nanomaterials such as pyrite nanocrystals for energy conversion applications. Such materials are particularly attractive for large scale applications.

In particular, we are intersted in materials which fall into the following categories:

i) Sustainable earth abundant semiconductor thin films for solar photovoltaics and photocatalysis. For example: SnS, ZnSnN₂, and CuSbS₂; quarternary kesterite semiconductors such as Cu₂ZnSnS(e)₄.

ii) Highly mismatched III-V semiconductors containing N and Bi, particularly those based on GaSb and InSb for thermophotovoltaics, mid-infrared (2-5 µm) and far-infrared (8-14 µm) applications.

iii) Transparent conducting oxides, such as ZnO, Ga₂O₃, CdO, In₂O₃ and SnO₂.
