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