Solar Energy at $1/Watt From 1366 Technologies

I was very happy wen i hear that a company like 1366 Technologies delivering solar energy at $1/Watt and to see the solid and simple technology behind this promise.
This company is working on improving multi-crystalline silicon solar panels.1366 Technologies
claim to have found ways to make them about as efficient as single-crystal silicon solar cells, which are more efficient but also more expensive, without losing the cost benefits. Three different innovations allowed them to produce their prototype 27% more efficient than conventional multi-crystalline silicon solar cells, bringing its total efficiency to 19.5%, about the same as single-crystal silicon solar cells.

First innovation is to add texture to the surface of the cells that allows the silicon to absorb more light,then the second innovation is that the silver wires harvest electrical current generated by the silicon,and the last:a set of wide, flat wires used to collect current from the thin silver wires.
It is very good invention.
