Kerf-Less Exfoliated Thin Silicon Wafer Prepared by Nickel Electrodeposition for Solar Cells

AgInSe2 thin films prepared by electrodeposition process

In this work, the one step electrodeposition process was used to prepare Ag-In-Se thin films. The films were deposited at room temperature from a bath containing 1-3x10 M AgNO3, 6x10 -2 M InCl3 and 3x10 -2 M of H2SeO3. The KSCN at a concentration of 0.681 M was used as complexing agent. The pH value of the solution was 1.4. Applied potentials to SCE were chosen between -0.3 V and -1.1 V. Films ...

Thin-film Silicon Solar Cells

The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...

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 ...
