Epitaxial Lift‐Off Process for Triple‐Junction Solar Cells Using Internal Push–Pull Stressors

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 3, Page 239-246, March 2026.
Epitaxial lift‐off of multijunction solar cells is achieved using internal push‐pull stressors to enable thin‐film release. An oxide sidewall protection layer ensures selective etching of the sacrificial layer while preventing damage to Al and P containing active layers.

Industrial Production of Perovskite–Silicon Tandem Solar Cells: The Characterization Challenge

Solar RRL, Volume 10, Issue 3, 13 February 2026.
Characterizing perovskite–silicon tandem solar cells industrially is challenging due to shared electrical terminals and perovskite metastability. We propose light‐emitting diode‐based external quantum efficiency and I–V measurements, model ion migration, and recommend light preconditioning for reliable cell measurements.

High stability near-broken gap junction for multijunction photovoltaics

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2018
High performance tunnel junctions were made from sputtered and annealed p-type CuAlO2 and n-type ZnSnO3 with suitable band alignment for both low resistance and alignment to typical inorganic materials needed for a tandem solar cell. The devices not only exhibit low resistance, they are also thermally stable, capable of sustaining postdeposition ...
