What is a p/n/p solar cell?

In this work we propose the use of p/n/p (or n/p/n) structures instead, that exhibit the same limiting efficiency that a dual-junction solar cell, but without the need of using tunnel junctions or wafer bonding schemes for interconnecting the cells. The proposed solar cell structure has three-terminals.

What is a solar cell p-n junction diode?

A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics – such as current, voltage, or resistance – vary when exposed to light. Individual solar cells can be combined to form modules commonly known as solar panels.

What is a photovoltaic (PV) cell?
