Silicon solar cells: Electrical properties of copper nanoclusters positioned in micropores of silver stripe-geometry elements
- 47 Downloads
Heterogeneous copper-silver contact stripe-geometry elements (SGEs) of solar cells are obtained by the chemical deposition of small copper particles on a silver surface and gaining access to silver micropores. Copper clusters are regularly distributed over the silver surface and enter the pores over the entire depth of the silver SGE arranged at the silicon solar cell. The morphological and electrical properties of the contact SGEs of porous silver are studied. In the absence of an applied electric field, 450- and 900-μA luminous currents and a 5-μA dark current are detected flowing along the porous metal.
