monocrystalline silicon solar cells with traditional aluminum back surface field process have achieved efficiency of 19.8% and 18.5%, respectively [2–5], very close to the limit of the current crystalline silicon production line. In order to fur-ther enhance the cell
The light-generated current and short-circuit current for an ideal solar are identical. Therefore, the largest current that may be extracted from a solar cell is the short-circuit current. The short-circuit current depends on the following factors: Solar cell area: The area of a solar cell strongly affects the short-circuit current. Hence, to ...
