• [001] facet exposed, were assembled and characterized in terms of the device performance, the kinetics of electron transport and back reaction. It was found that the TiO2-spheres-based DSCs generated an energy conversion efficiency of 7.57%, which is comparable to the conventional TiO2 nanoparticles

• ability of MWCNTs to serve as an energy-conversion material [9][10]. In this paper, we build up a simple photovoltaic device based on MWCNT–Si Schottky heterojunction. Photovoltaic measurements for the in-plane and top-down geometries of the device were performed. In particular, we find that the top-down

• also enhance scattering at their resonances. This effect has been exploited in solar cells, for example, enhanced scattering by arrays of silver nanoparticles permits a thickness reduction of Si solar cells without compromising the intrinsic energy conversion efficiency [44][45][46].
