Perovskite-perovskite tandem photovoltaics with optimized band gaps [PDF]

open access: yesScience, 2016
Tandem perovskite cells The ready processability of organic-inorganic perovskite materials for solar cells should enable the fabrication of tandem solar cells, in which the top layer is tuned to absorb shorter wavelengths and the lower layer to absorb the remaining longer-wavelength light.

Curtailing Perovskite Processing Limitations via Lamination at the Perovskite/Perovskite Interface [PDF]

open access: yesACS Energy Letters, 2018
Standard layer-by-layer solution processing methods constrain lead–halide perovskite device architectures. The layer below the perovskite must be robust to the strong organic solvents used to form the perovskite while the layer above has a limited thermal budget and must be processed in nonpolar solvents to prevent perovskite degradation. To circumvent
