Figure 3From: Large-diameter titanium dioxide nanotube arrays as a scattering layer for high-efficiency dye-sensitized solar cellDSSC angle performance and IPCE. (a) Variation of efficiency with the angle of incidence of incoming light with respect to the three types of cells. (b) IPCE of the TP (3 L)-based DSSCs coupled with different scattering layers, i.e., LTNA and STNA.Back to article page
