Built-in Voltage: Course Photovoltaics #07

Let's take a closer look at the pn-junction. We explain how band bending occurs and what the band diagram of a pn junction looks like. We will also learn about the built-in voltage of a pn junction and explain how to calculate it. ---------------------------------------------------- This video is part of the PViTeach program, which offers many free courses on photovoltaics and even offers the opportunity to earn an official certificate.
