    Superstrate-type photovoltaics with copper indium sulfide (CuInS2) fabricated by solution processes: correlation between interfacial charge transfer and solar cell performance

    Copper indium sulfide, CuInS2 (CIS) semiconductors have currently attracted a great deal of attention as photosensitizers for solar cells. In this study, CIS/CdS/TiO2 solar cells were prepared by a simple, low-co...

    Lattice Vibrational Modes in 1222 Phase of Pb-Sr-La-Ln-Cu-O System (Ln; Gd, Dy, Ho, Er)

    Measurements of infrared absorption in insulating compounds of the 1222 phase of Pb-Sr-La-Ln-Cu-O system have been made. Lanthanoid (Ln) ions of Er, Ho, Dy and Gd have been used. Absorption peaks near 600 cm−1 an...

    Infrared Absorption in Single Crystals of Bi-Sr-(Ca)-Cu-O System

    Lattice absorption measurements in the spectral region between 750 cm−1 and 400 cm−1 have been made in single crystals of semiconducting Bi2Sr2CuO6 and superconducting Bi2Sr2CaCu2O8. The phenomenon known as the “...
