dc.description.abstractIn this study we report on the photovoltaic performance of Cu(2-x)S (x = 1, 0.03) quantum-dot (QD) sensitized liquid-junction solar cells. The QDs were grown with successive ionic layer adsorption and reaction. The CuS phase in the as-grown QDs was transformed into Cu(1.97)S after annealing. The assembled Cu(1.97)S cells yielded a best power conversion efficiency eta of 0.90% under illumination of 100 mW/cm(2). The CuS cell had an eta similar to 75% lower than that of Cu(1.97)S. The external quantum efficiency (EQE) spectrum of Cu(1.97)S covers the spectral range of 350-1100 nm with a maximal EQE of 63% at gimel = 500 nm and an average EQE of 47% over the entire spectral range. This spectral range is also two times broader than that of N3 dye. The results show that Cu(2-x)S QDs can be used as highly efficient broadband sensitizers for solar cells. (C) 2011 Elsevier B.V.
