Adhesion of antireflective coatings in multijunction photovoltaics [PDF]

2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC), 2016
The development of a new composite dual cantilever beam (cDCB) thin-film adhesion testing method is reported, which allows the measurement of adhesion on the fragile thin substrates used in multijunction photovoltaics. We address the adhesion of several antireflective coating systems on multijunction cells. By varying interface chemistry and morphology,

Steering perovskite precursor solutions for multijunction photovoltaics

Nature
Abstract Multijunction photovoltaics (PVs) are gaining prominence owing to their superior capability of achieving power conversion efficiencies (PCEs) beyond the radiative limit of single-junction cells1–8, for which improving narrow-bandgap (NBG) tin–lead perovskites is critical for thin-film devices9. Here, with a focus on understanding the
