Figure Lengend Snippet: Absorbance ( a , c ) and normalized photoluminescence (PL) ( b , d , excitation wavelength: 355 nm) spectra of copper indium sulfide (CIS) nanocrystals (NCs) prepared using different synthesis times at 150 °C (Cu-In-S ratio = 1:1:2) ( a , b ), and using different synthesis temperatures ( c , d ). At 175 °C for longer reaction times precipitation occurs.
Article Snippet: For solar cell preparation, first, activated mesoporous TiO 2 electrodes were immersed into concentrated colloidal solutions of CIS NCs for a given time followed by rinsing and passivation coating with a thin ZnS layer obtained by SILAR deposition.
