Characterization of tandem organic solar cells [PDF]

open access: yesNature Photonics, 2015
The tandem solar cell approach is a promising concept for organic photovoltaics (OPVs). However, efficiency determination or, in general, electrical characterization of multi-junction solar cells is challenging. We performed a literature survey of publications reporting tandem OPV characterizations over the period January 2009 to September 2014 and ...

A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

open access: yesAdvanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...
