In this work, we obtain the highest reported power conversion efficiency (13.3%) for sulfur-free CIGSe solar cells by solution processing. Intentional sodium incorporation is achieved directly by dissolving sodium salts in the ink. The effect on sola

Liquid film processing of Cu(In,Ga)Se 2 absorber layers has the potential to lower the cell production costs significantly namely because of the absence of vacuum steps and high material utilization. In this work an ink system based on metal carboxyl

In this work, a low cost solution-based method for the deposition of uniform Cu-In-Ga layers compatible with roll-to-roll processing is described. As ink system we use metal carboxylates dissolved in a mixture of a nitrogen containing base and an alc

Sm(II)-modified periodic mesoporous silica (PMS), Sm[N(SiHMe2)2]2(THF)x@MCM-41, was used for the synthesis of Sm(II) alkyl, alkoxide, and indenyl surface species via secondary ligand exchange. The performance of the novel Sm(II)-based organometallic

Cu 2 ZnSnSe 4 films were prepared by selenization of metallic precursors obtained by a new wet process involving metal formates. Cu(HCOO) 2 and Zn(HCOO) 2 were used as copper and zinc sources respectively, while tin was introduced as a methoxide. The

The synthesis of highly ordered cubic mesoporous silica MCM-48 with tunable pore sizes in the range 1.6−3.8 nm is reported. Pore size control has been achieved by using (mixtures of) gemini surfactants, [CH3(CH2)nNMe2(CH2)mNMe2(CH2)nCH3]2+2Br-, of

High-quality MCM-48 materials were prepared by employing C16-12-16 and C22-12-22 gemini surfactants, respectively, and hydrothermal post-treatment methods. Metalorganic titanium reagents comprising alkoxide and amide complexes were grafted onto the d
