![]() This emerging technology has several distinct advantages such as providing potent candidates for top cells in a tandem solar cell architecture with Si as the bottom cells. The world energy and economy can be changed with the development of stable perovskite materials which are easily deposited onto Si solar cells without the need of lattice matching. The World Economic Forum in 2016 recognized them to be among the top 10 technologies in 2016. However, the perovskite solar cells (PSCs), with lab-scale PCE of 22.7%, have recently emerged as one of the most exciting fields of research of our time. ![]() ![]() Si-based solar cells have dominated the terrestrial solar panel market with an average panel power conversion efficiency (PCE) of around 20%, while the record cell efficiency stands just above 26%, which is very close to the Shockley-Quiesser (S-Q) limit of single-junction solar cells (29% for silicon).
