Used ROTH & RAU SiNA #186034 for sale

ROTH & RAU SiNA is the most advanced, world-leading solar production equipment currently available on the market. By combining the cutting-edge precision of modern laser processing with unmatched process control and monitoring systems, it allows the production of fully automated, high efficiency solar cells with outcomes that are significantly superior compared to the alternatives. The key feature of SiNA is its short process time -from 1 to 6 minutes- that allows the production of a high quantity of photovoltaic wafers in a significantly reduced amount of time. This is achieved by using all-in-one laser dicing, front- and back-side patterning, and pattern recognition, without the need for manual labor. Additionally, the precision and alignment of the laser, with an accuracy of +/- 5 μm, combined with the advanced process control and monitoring systems, guarantee an optimal production of solar photovoltaic cells. In terms of physical components, ROTH & RAU SiNA includes a laser dicing station, a roll-to-roll automatic front-side laser patterning station, a back-side laser patterning station and a highly efficient pattern recognition station. The laser dicing station utilizes a multimode pulsed fiber laser tuned to the solar cell material of choice. This allows a process time of up to 200 μs per cell with an average laser ablation of just 0.8 μm. The laser patterning station combines chemical-mechanical polishing (CMP) technology with laser patterning to drastically reduce process time while ensuring an excellent step coverage on the wafer. Lastly, the pattern recognition station uses a combination of optical and piezoelectric sensors to inspect each cell and determine the exact layout of the photovoltaic cell's different layers. This helps to avoid any defective products and ensures highly efficient solar cells. SiNA is the premier choice for solar production and provides the most advanced, efficient and cost-effective solar cell production solutions available. The combination of superior quality, precision and speed, makes it the perfect choice for any high throughput solar production line.
