Halide perovskite photovoltaics

AbstractHalide perovskites are a new class of materials that can be processed at low cost yet exhibit excellent optoelectronic properties – a combination rarely seen in semiconductors. This review highlights their exciting promise for inexpensive and efficient solar photovoltaic technologies. The work details the rapid progress in efficiency of solar cells – with efficiencies already rivalling commercial leading technologies such as silicon – and describes the physics of the materials and devices that lend themselves to photovoltaic applications. This work also describes the challenges to realise their true potential as disruptive photovoltaic technologies that could play a key role in decarbonisation in the coming decades, including stabilising long-term operation and furthering understanding of this fascinating class of semiconducting materials.KEYWORDS: Halide perovskitesphotovoltaicsrecombinationoptoelectronics AcknowledgementsTerry Yang, Chieh-Szu Huang and Xian Wei Chua for helpful feedback on the manuscript.Disclosure statementThe author is a co-founder of Swift Solar, a company commercialising high-performance perovskite photovoltaics.Additional informationFundingThe author acknowledges support from the Royal Society and Tata Group (UF150033) and the Engineering and Physical Sciences Research Council (EPSRC, EP/S030638/1 and EP/V027131/1).Notes on contributorsSamuel D.
