Lui et al.1 report new ‘perovskite-based’ solar cells having a photon-to-electron-conversion-efficiency (PCE) of a remarkable 15.4%. Traditional photovoltaic technology is dominated by c-Si, with inorganic thin film entrants CdTe, CIS and GIGS making substantial market inroads. Pipeline technologies such as dye-sensitized solar cells (DSSCs) and organic solar cells (OSCs)2 promise ultra-low manufacturing costs as well as light-weight, flexible modules. As yet, the ‘pipeline’ is yet to deliver commercial product with long-term stability and module-scale PCEs being hurdles. The perovskite technology emerged from DSSCs as p-type materials, and then as combinatorial replacements for the dye and hole-transport components.3 |
