Metallized arrays of three-dimensional (3D) nanoarchitectures offer new and exciting prospects in nanophotonics nanoelectronics. Engineering these repeating nanoarchitectures, which have dimensions smaller than the wavelength light source, enables in-depth investigation unprecedented light-matter interactions. Conventional metal nanomanufacturing relies largely on lithographic methods that are limited regarding choice materials machine write time restricted to flat patterns rigid structures....

Carbon nanotube electrode–laminated perovskite solar cells in combination with n‐type tunnel oxide–passivated contact silicon demonstrate a high power conversion efficiency (PCE) of 24.42% when stacked tandem. This is compared conventional indium tin oxide/MoO x ‐deposited which give an 22.35% the same four‐terminal tandem system. Despite higher transmittance carbon electrode than that infrared range, electrode‐laminated devices show lower region due to total internal reflection and...
Abstract Plasmonic nanostructures, which exhibit prominent localized surface plasmon resonance (LSPR) properties, are highly desirable for organic solar cells (OSC) and light‐emitting diode (OLED) devices.
