Flexible, Polymer‐Supported, Si Wire Array Photoelectrodes
Source abstract
Abstract
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.

25. Efficiency η= (Jsc)(Voc)(FF)/P whereP= 100 mW cm−2andJscis assumed to be 35 mA cm−2. From Table 1 for a polymer‐supported wire array at 60 mW cm−2(approximately the same above‐bandgap photon flux as 100 mW cm−2AM 1.5) the uncorrected FF = 0.35. BecauseVoc= (kT/q)ln(Jsc/Jo) increasingJscfrom 7.9 to 35 mA cm−2would increase theVocby 38 mV toVoc= 428 mV. The result isη= 5.2%.
