Co-sensitisation of methylammonium lead tri-bromide perovskite solar cells with red (D205) and blue (SQ2) organic dyes improves device efficiencies and allows device colour tuning. Sensitising the film after perovskite crystallisation produces higher device efficiencies (2.6% SQ2, 3.1% D205) than perovskite-only devices (2%) and devices sensitised before the perovskite layer deposition (1.5% SQ2, 2.0% D205).
甲脒铅三溴化混合染料敏化钙钛矿太阳能电池可以同时敏化红光（D205）和蓝光（SQ2）有机染料，从而提高器件效率并实现器件颜色可调。在钙钛矿结晶后对薄膜进行敏化，产生的器件效率高于仅用钙钛矿（2%）和在钙钛矿层沉积前敏化的器件（SQ2 为 1.5%，D205 为 2.0%）。
