Solar cell structure with by-pass diode and wrapped front-side diode interconnection

摘要

A solar cell structure includes a solar cell having a front side and a back side and an active semiconductor structure. The solar cell produces a voltage when the front side is illuminated. The solar cell is protected by a by-pass diode structure including a by-pass diode positioned at the back side of the solar cell. A first electrical interconnection structure extends between the back side of the solar cell and the first diode terminal, and a second electrical interconnection structure extends between the front side of the solar cell and the second diode terminal. An entire length of the second electrical interconnection structure contacts the solar cell.
