Wafers: the building blocks of photovoltaic panels

  1. Diamond-edged wafers: Diamond-edged wafers are manufactured using a cutting technique that reduces internal stresses and micro-cracks in the wafers. This method improves wafer quality and reduces breakage rates during the solar cell manufacturing process.
  2. Textured wafers : Texturing solar wafers increases their ability to capture light by reducing reflection and trapping light inside the solar cells. This improves the efficiency of solar cells and, consequently, of solar panels.
  3. Black wafers: Black wafers, also known as black silicon wafers, are treated with special methods to further reduce light reflection and improve light absorption. This leads to higher energy efficiency in solar cells.
  4. Heterojunction wafers: Heterojunction wafers are an innovation that combines amorphous and crystalline silicon layers to create a solar cell with enhanced energy efficiency. This technology offers advantages such as higher open-circuit voltages and improved temperature tolerance.
