High fabrication yield organic tandem photovoltaics combining vacuum- and solution-processed subcells with 15% efficiency

High fabrication yield organic tandem photovoltaics combining vacuum- and solution-processed subcells with 15% efficiency, Published online: 23 April 2018; doi:10.1038/s41560-018-0134-z

Organic tandem solar cells combining solution- and vapour-deposited layers are difficult to fabricate due to the degradation of the underlying subcell during the deposition of the next subcell. Here, Che et al. design a charge recombination layer that protects the underlying cell and leads to 15% average PCE for 2 mm2 devices and 11.5% PCE for 1 cm2 devices.

Since the first publication of all-solid perovskite solar cells (PSCs) in 2012, this technology has become probably the hottest topic in photovoltaics. Proof of this is the number of published papers and the citations that they are receiving—greater than 3,200 and 110,000, respectively— in just the last year (2017). However, despite this intensive effort, the working principles of these kind of devices are not yet fully understood. The manuscript of Ravishankar et al. will contribute significantly to this debate, as the authors have shown that the work function of the electron selecting layer plays a minor role on the final open circuit voltage, V oc .
