The second generation solar cells such as organic photovoltaics (OPVs), dye-sensitized solar cells (D-SSCs), and thin-film solar cells have been considered as promising candidate to replace conventional silicon solar cells because the second generation solar cells can reduce the power generation cost and find new applications. Among them, the sensitized solar cells have a unique deivce structure unlike the other pn junction solar cells because they are composed by electron conductors, sensitizers, and hole conductors. Therefore the sensitized solar cells could reduce the materials synthesis and processing cost. Recently, inorganic semicondurs such as CdS(e), PbS(e), Bi2S3, and Sb2S3 have been considered as new sensitizers owing to their prominent properties such as convenient bandgap tunability, easy charge separation, high absorptivity, and good stability. Here I would like to introduce the research trend of inorganic semiconductor-sensitized solar cells and share research progress in my group. |
