Solar cells with grid wire interconnections

A plurality of solar cells is connected together in a shingled fashion. Each of the solar cells includes grid wires that are attached to an electrode of the solar cell so as to receive charge carriers produced when photons are absorbed by the solar cell. The grid wires are then interconnected with adjacent solar cells when the solar cells are shingled together. The grid wires may be applied to the solar cells via a laminate and the electrical interconnection of the grid wires may be achieved by the use of a conductive epoxy.

Electric conductive silver paste and manufacturing method thereof

The invention discloses electric conductive silver paste and a manufacturing method of the electric conductive silver paste. The electric conductive silver paste comprises, by mass percentage, 35 - 65 % of micron-sized silver powder, 1-10 % of nanometer-sized silver powder of or 1-20 % of nanometer-sized silver and other metal alloy powder, and 1-10 % of an organic carrier; for ceramics, solar cell silver paste comprises 2-15 % of unleaded glass powder, each component is manufactured in parts, weighed, mixed and stirred or mixed and rapidly scattered, and ultrasonic-vibrated or fine adjusted of viscosity of solvent, and therefore the electric conductive silver paste is obtained. Due to the fact that the nanometer-sized silver powder or the nanometer-sized silver alloy powder is mixed with the micron-sized silver powder, intensity of conductivity and a circuit is improved, adhesive force of crushing resistance and a base plate is improved, at the same time unleaded slurry good in thixotropy, low in contacting resistance and low in piece-needed slurry amount replaces lead slurry materials, the electric conductive silver paste is used for manufacturing crystalline silicon solar cells, improves photoelectric conversion efficiency, accords with environmental-protection ideas, and can be produced in large scales continuously.

Engineered structure for charge storage and method of making

Engineered structure for charge storage. An electrolyte is disposed between two electrically conducting plates, each plate serving as a base for an aligned array of electrically conducting nanostructures extending from the surface of each plate into the electrolyte. The nanostructures have diameter and spacing comparable to the dimension of an ion of the electrolyte. An electrically insulating separator is disposed between the two plates. A CVD process (or other processes yielding similar results) is used to make the aligned array of electrically conducting nanostructures.
