This paper investigates the crystal structure and optical absorption of Ge/TiO2 composite thin films for next-generation solar cells. X-ray diffraction patterns reveal that an anatase-dominant structure of TiO2 matrix is successfully obtained by compositional optimization. The optical absorption spectra are obviously shifted to visible- and near-infrared-regions due to the presence of Ge nanogranules, suggesting that Ge/TiO2 composite thin films are therefore capable of converting solar radiation to electrical power. Accordingly, the two valuable properties of anatase-dominant structure and favorable absorption are found to be retained simultaneously in the Ge/TiO2 composite thin films.
