Granular Silicon
Silicon is the main component in crystalline solar cells, the dominant form of solar cells on the market today. In order to generate electricity from the sun for a cost equal to or less than carbon emitting sources of electricity like coal fired plants, the cost to manufacture a solar cell must decrease and the efficiency of those cells must increase. This is often called “grid-parity.” A better process to manufacture silicon is the key to solving both of those problems and to making grid-parity a reality.
Peak Sun Silicon is in business to solve these problems. Peak Sun’s unique tribromosilane-based, fluid-bed polysilicon meets all the requirements for mass deployment of solar electricity. Our high purity product delivers high conversion efficiency of sunlight directly into electricity. This means better performance of your solar cells and panels.
Peak Sun uses a continuous-manufacturing process that operates at near atmospheric pressure and lower temperatures than competitive processes, and energy costs are significantly reduced compared to competitive technologies. Further, Peak Sun's silicon is delivered in dense spherical-bead form with uniform particle size. These qualities make it the ideal feedstock for the continuous substrate manufacturing processes essential for rapid solar cell capacity expansion and cost reduction.
