RTP-like processing, in which an increase in the temperature of the semiconductor sample is produced by the absorption of the optical flux, is now used for a host of solar cell fabrication steps, ncluding phosphorus diffusion for N/P junction formation and impurity gettering, hydrogen diffusion for impurity and defect passivation, and formation of screen-printed contacts using Ag-ink for the front and Al-ink for back contacts, respectively. Some solar cell companies have successfully applied our advanced Rapid Thermal Processing (RTP) technology to its process for creating highly efficient and durable CIGS solar cells. This eliminates a key process bottleneck found in many state-of-the-art process implementations and enables the use of low-cost substrates in ways that were not considered possible before. In Rapid Thermal Processing, a layer is heated for a very brief period only in a highly controlled way. For instance, RTP techniques can flash-heat a layer for just several picoseconds and put energy just into the top several nanometers of a layer in a highly controlled way *- while leaving the rest of the layer unaffected. RTP has a secondary benefit of reducing the energy payback time of their solar cells to less than two months (for the full panel). By comparison, a typical silicon solar panel has an energy payback time of around three years, and a typical vacuum-deposited thin-film cell has one of **2 years.
