Alignment and Transfer of Silver Nanowire Arrays onto Unconventional Substrates for Optoelectronic Devices via Dielectrophoresis Force

As for AgNWs arrays for solar cell applications, our goal is to deposit AgNWs arrays on solar cells for enhancing photovoltaic conversion efficiency. The resulting alignment is ideal when AgNWs arrays are aligned on interdigitated electrodes by dielectrophoresis force in previous experiments, but not for aligning AgNWs arrays directly on silicon solar cell with pyramidal structure texture. In order to solve the limitations, the alignment is integrated with the transfer printing technique, and the fabrication approach is low-cost, fast, and scalable to large-area NW arrays, which offers flexible applications for developing NW-based devices with unconventional substrates.
