Why are silicon solar cells a popular choice?

What is a silicon PV cell?

A typical silicon PV cell is a thin wafer, usually square or rectangular wafers with dimensions 10cm × 10cm × 0.3mm, consisting of a very thin layer of phosphorous-doped (N-type) silicon on top of a thicker layer of boron-doped (p-type) silicon. You might find these chapters and articles relevant to this topic.

How efficient are silicon solar cells?

As one of the PV technologies with a long standing development history, the record efficiency of silicon solar cells at lab scale already exceeded 24% from about 20 years ago (Zhao et al., 1998).

What happens if a solar cell is made of silicon?

These higher energy photons will be absorbed by a silicon solar cell, but the difference in energy between these photons and the silicon band gap is converted into heat (via lattice vibrations — called phonons) rather than into usable electrical energy. The most commonly known solar cell is configured as a large-area p–n junction made from silicon.

How much voltage does a solar cell produce?

When there is no external load applied, most silicon solar cells produce roughly 0.5 to 0.6 volts DC, which is the main characteristic of a pn-junction. A solar cell creates its maximum output voltage, also known as its open-circuit voltage, VOC, when there is no load connected or a very low current demand.
