If you’re looking to find suitable materials for efficient solar cells, you’ll want to get in touch with a trusted silicon wafer supplier. They can provide you with the substrates you need to produce solar cells that are effectively matched to the spectrum of available light.While some solar cells are specifically designed to convert wavelengths of solar light that reach the surface of the Earth, others are specifically optimized to absorb light beyond the Earth’s surface.

Facts About Solar Wafers You Should Know

Solar Cells Are Made from Different Types of Materials

Multiple physical configurations operate several types of light-absorbing materials to take advantage of various charge light absorptions and charge separation mechanisms. Some of the most commonly used materials for photovoltaic solar cells include the following:

  • Monocrystalline silicon
  • Polycrystalline silicon
  • Amorphous silicon
  • Cadmium telluride
  • Copper indium selenide/sulfide

These bulk materials are cut into wafers that measure between 180 to 240 micrometers thick before they’re processed like other types of semiconductors.

Silicon Is the Only Well-Researched Material for Solar Cells

Some materials are used to create thin-films layers and organic dyes and polymers that are deposited on supporting substrates. However, others that are made from nanocrystals are used as electron-confined nanoparticles or quantum dots. In both thin-film and bulk forms, silicon remains to be the only well-researched material.

Solar Cells’ Fabrication Requirements Are More Relaxed

Although solar cells share some of the manufacturing and processing techniques as computer and memory chips, they have less stringent requirements for quality control and cleanliness. In other words, the fabrication requirements for solar cells are more relaxed than other semiconductor devices. For this reason, today’s large-scale commercial solar cell factories create screen-printed single-crystalline or poly-crystalline silicon solar cells.
