A photovoltaic cell is the component of a solar panel that converts sunlight into electricity. These cells are typically made of a crystalline silicon wafer. When sunlight hits the silicon, electrons in the cell are energized and begin to move, initiating a flow of electricity.
However, there are differences between the two kinds of solar panels in their cell composition. Solar cells used on monocrystalline panels are made of silicon wafers where the silicon bar is made of single-cell silicon and they are sliced into thin wafers. The electrons have more space to move around thereby allowing a greater flow of energy.

Defining Photovoltaic Wafers a.k.a Solar Cells. Photovoltaic wafers or cells, also known as solar cell wafers, use the photovoltaic effect to convert sunlight to electricity. These cells come in various types, from the non-crystalline amorphous silicon to the more efficient single-crystal monocrystalline silicon.
Cell Fabrication – Silicon wafers are then fabricated into photovoltaic cells. The first step is chemical texturing of the wafer surface, which removes saw damage and increases how much light gets into the wafer when it is exposed to sunlight.
