Photovoltaic Series Thermal Deposition Sources for Thin Film CIGS from Veeco azonano.com Background Thin film solar cells have attracted considerable interest from solar cell manufacturers because of their potential to significantly reduce manufacturing costs compared to current Si-based devices. However, one of the most demanding challenges is transitioning CIGS processes from R&D to high-volume manufacturing. Accordingly, manufacturing lines must have low capital costs, produce consistent solar devices and ramp quickly to generate revenue. Thermal Deposition Sources These factors are particularly important in relation to deposition equipment due to their impact on device efficiency. Deposition sources must be reliable and deliver stable flux over time in capacities sufficient for a week or more of uptime. Veeco provides this solution in our production-capacity PV-Series™ Thermal Deposition Sources for CIGS, capable of depositing across 120cm-wide substrates - providing the most innovative deposition technologies presently on the market. For over 20 years, Veeco has excelled at designing and manufacturing material-specific thermal deposition sources for both R&D and production thin film deposition systems. Our focus has been on providing reliable sources with high material utilization while ensuring the highest level of performance. Veeco thermal deposition sources demonstrate excellent thickness uniformity and compositional control in some of the most demanding electrical and optical applications. Veeco sources have become the production standard because of their large capacities, high temperature operation and long term stability - all critical factors in the CIGS deposition process. Veeco’s PV-Series Thermal Deposition Sources, incorporating patented design elements, are an ideal choice for R&D and high-volume manufacturing of CIGS solar cells - enabling you to meet your process goals today and tomorrow. Anatomy of a CIGS Deposition System Figure 1 shows a typical CIGS deposition module incorporating Veeco PV-Series Thermal Deposition Sources. The module is shown optimally configured with six SUMO® sources and one selenium valved source, providing high material utilization (50-60%) and low thickness non-uniformity (<±5%) on 120cm-wide substrates. Veeco PV-Series SUMO Sources and Valved Sources are available in production capacities, allowing for a week or more of continuous operation...
