BPhO lecture: Photovoltaics, solar energy: present status and emerging perovskites

Most of the world’s solar cells rely on silicon, and convert roughly 17–25% of the light that falls on them into electricity — almost 10 times better than the humble leaf does through photosynthesis. But their thick chunks of pure silicon make them expensive to build. Thin-film solar cells, containing leaner slivers of other semiconductors, are cheaper but generally less efficient; it has taken decades for their efficiencies to creep above 15%. Perovskite cells combine the best attributes of both and are easy to make.

This talk will explore perovskite solar cell research and their potential impact.

Professor Henry Snaith

Prof. Henry Snaith is the Group Leader of 'The Photovoltaic and Optoelectronic Device Group', Department of Physics at Oxford University. His research is at the forefront of perovskite solar cell research. Nature named him as one of the top 10 people making scientific break-throughs in 2013.

Snaith was elected a Fellow of the Royal Society (FRS) in 2015. His certificate of election reads:

Professor Henry Snaith has pioneered the development of hybrid materials for energy and photovoltaics through an interdisciplinary combination of materials synthesis, device development, advanced optoelectronic characterisations and theoretical studies. He has created new materials with advanced functionality and enhanced understanding of fundamental mechanisms. His recent discovery of extremely efficient thin-film solar cells manufactured from organic-inorganic metal halide perovskites has reset aspirations within the photovoltaics community. His work has started a new field of research, attracting both academic and industrial following, propelled by the prospect of delivering a higher efficiency photovoltaic technology at a much lower cost than existing silicon.
