Single-nanowire solar cells with a unique light-concentration property are expected to exceed the Shockley–Queisser limit. The architecture of single nanowire is an important factor to regulate its optical performance. We designed a trilobal silicon nanowire (SiNW) with two equivalent scales that possesses superior light-absorption efficiency in the whole wavelength range and shows good tolerance for incident angle. The electric field distribution in this geometry is concentrated in the blade wi
