Economic pulse electrodeposition for flexible CuInSe2 solar cells

ONE STEP ELECTRODEPOSITION OF CuInSe2 THIN FILMS

Formation of CuInSe2 (CIS) thin films from aqueous solution containing citrate as complexing agent is reported. The surface morphology and the composition of the deposited films are characterized by scanning electron microscopy (SEM). The texture of the deposits and their compositions are analyzed by X-ray diffraction and transmission electron microscopy (TEM). Annealing of the films at 350°C i...

Pulsed electrodeposition of CuInSe2 films for photovoltaic applications

Copper indium diselenide thin films have been prepared onto ITO (In2O3:Sn) substrates by a newly developed pulsed electrodeposition method. The proposed scheme consists of a cyclically repeated pulsed potential sequence at the corresponding deposition potentials of elemental Cu, Se and In. When the potential is stepped back to the initial Cu electrodeposition potential after a full cycle to sta...

Electrodeposition of Photoactive Silicon Films for Low-Cost Solar Cells

Here we demonstrate progress on electrodeposition of photoactive silicon films from an environmentally friendly molten CaCl2 electrolyte, which is the first step of a new route to a practical low-cost silicon solar cell. We report electrodeposition of severalmicron thick silicon films on a graphite substrate in a bath of molten CaCl2 containing SiO2 nanoparticles. The best silicon deposits was ...

Triboelectric-generator-driven pulse electrodeposition for micropatterning.

By converting ambient energy into electricity, energy harvesting is capable of at least offsetting, or even replacing, the reliance of small portable electronics on traditional power supplies, such as batteries. Here we demonstrate a novel and simple generator with extremely low cost for efficiently harvesting mechanical energy that is typically present in the form of vibrations and random disp...
