Arrays of oriented, crystalline Si wires are transferred into flexible, transparent polymer films. The polymer‐supported Si wire arrays in liquid‐junction photoelectrochemical cells yield current‐potential behavior similar to the Si wires attached to the brittle growth substrate. These systems offer the potential for attaining high solar energy‐conversion efficiencies using modest diffusion length, readily grown, crystalline Si in a flexible, processable form.
