P-type nitrogen-doped ZnO nanoparticles stable under ambient conditions.

Zinc oxide is considered as a very promising material for optoelectronics. However, to date, the difficulty in producing stable p-type ZnO is a bottleneck, which hinders the advent of ZnO-based devices. In that context, nitrogen-doped zinc oxide receives much attention.

Synthesis of p-type transparent LaOCuS nanoparticles via soft chemistry.

We report here for the first time on the synthesis of nanoparticles of the p-type transparent conductor LaOCuS. Nanoparticles were obtained via a solvothermal route in ethylenediamine with dehydrated lanthanum chloride (LaCl(3).7H(2)O), copper monooxide, and elemental sulfur as precursors.

Simple and reproducible procedure to prepare self-nanostructured NiO films for the fabrication of P-type dye-sensitized solar cells.

Porous and nanostructured thin films of NiO (3.5 microm thick) were prepared on FTO coated glass by annealing nickel acetate films obtained by recrystallization under hydrothermal conditions in the presence of hexamethylenetetramine. The photovoltaic performances of the NiO films were optimized with coumarin C343 as sensitizer and iodide/triodide as redox mediator and led to the following values of V(OC), J(SC), ff, and eta: 117 mV, 0.
