Prof. Snaith has striven to develop new low cost photovoltaic technologies based on simply processed materials, which have promised to deliver solar energy at a fraction of the cost of incumbent silicon modules. Since 2012, his research has led to a transformation in the photovoltaics research community. Through a series of key discoveries, he found that metal halide perovskite materials, which had been overlooked for decades because of their very low photovoltaic energy efficiency in earlier days, can be employed as thin film absorber layers in highly efficient solar cells. Prof. Snaith has significantly raised the energy efficiency of the perovskite solar cells from 10.9% in his first publication to over 22% in single junctions, and more recently to 25% by combining perovskites with crystalline silicon cells. Potentially, the perovskite-on-silicon tandem cells may deliver a photovoltaic technology capable to surpassing the 30% efficiency mark, making them very promising for industrial applications. Another huge benefit of these perovskite solar cells Prof. Snaith has found is their low cost, thanks to the solution based materials processing method and the simple layered device structures. He has also significantly improved long-term stability of perovskite solar cells and discovered numerous key fundamental aspects of the perovskites semiconductors, which helped broaden the application range of these materials to light emission, radiation detection, memory, and sensing. Prof. Snaith’s work toward a significant cost reduction in photovoltaic solar power and semiconductor industry will propel the human society to a sustainable future.
“I have been remarkably fortunate to discover that this previously unexplored family of materials, metal halide perovskites, are like no other semiconductor material studied before, and promise to be transformative in photovoltaic solar energy. It is a huge honor to be the inaugural Blavatnik UK Laureate in the Physical Sciences.”
