What are the skills and competencies required for a solar cell efficiency engineer or analyst?

When light hits the solar cell, it excites electrons in the semiconductor material, creating electron-hole pairs. The electric field at the p-n junction separates these electron-hole pairs, with the electrons flowing to the n-type layer and the holes flowing to the p-type layer. This separation of charges creates a potential difference, or voltage, across the solar cell. When the solar cell is connected to an external circuit, this voltage causes the electrons to flow through the circuit, generating an electric current.
