Computer aids to the design of thin film circuits.
… a digital computer can assist in the design of thin film circuits. One of the main advantages of thin film technology is that very accurate resistors can be fabricated on the slice. A set of programs have been developed such that the resistor geometries can be synthesised entirely automatically. …

Characterization and simulation of three-dimensional solid-state solar cells
Introduction : The newest PV technology that uses less material and cheaper materials and deposition methods (in order to lower the cost even more) resulted in extremely thin absorber solar cells, or ETA-cells. Such ETA-layers need to be applied to a nano-structured substrate. Dye-sensitized solar …
