High-efficiency facilities for PERC, TOPCon, HJT and next-generation photovoltaic technologies.
The global transition toward renewable energy is accelerating the demand for high-efficiency solar cell manufacturing facilities. From mono PERC to advanced technologies such as TOPCon and HJT, modern solar manufacturing requires precision-controlled environments, high-throughput production lines, and robust utility infrastructure.
At Nexiom, we design and engineer state-of-the-art solar cell manufacturing facilities that integrate process requirements, cleanroom environments, and industrial-scale infrastructure. Our solutions enable manufacturers to achieve high yield, operational efficiency, and scalability, while aligning with global sustainability and ESG goals.
Engineering Philosophy: Throughput, Precision & Sustainability
Solar cell manufacturing combines semiconductor-like precision with industrial-scale production.
Solar cell manufacturing demands a unique engineering approach that bridges semiconductor-level precision with industrial-scale throughput. Each process step from wafer texturing through final testing requires tight environmental control, optimized material flows, and integration of both wet chemistry and high-temperature thermal processes.
Our engineering philosophy centers on three pillars: throughput optimization for competitive cost-per-watt, process precision for high cell efficiency and yield, and sustainability for energy and water efficiency aligned with ESG objectives. Every facility design decision is evaluated against its impact on production capacity, quality consistency, and environmental performance.
Key principles that guide our solar facility engineering:
- High-volume, continuous production lines
- Controlled environments for critical processes
- Integration of wet chemistry and high-temperature processes
- Efficient material flow and automation

Process & Facility Design Engineering
Our engineering integrates process efficiency with industrial scalability.
Process and facility design for solar manufacturing begins with end-to-end process flow analysis that maps every step from wafer receiving through cell testing and sorting. Zoning strategies separate wet chemistry areas, high-temperature diffusion and firing zones, and cleanroom metallization processes while maintaining efficient material flows that minimize handling damage and contamination risk.
Cleanroom design addresses ISO-classified environments for critical processes where particle control directly impacts cell efficiency. Utility infrastructure including DI water, process gases, compressed air, and vacuum must be designed with capacity, purity, and reliability that match process requirements at full production scale.
Our process and facility design engineering scope includes:

We design integrated facilities that support the complete production flow from wafer texturing through final cell testing and sorting, with optimized layouts that minimize material handling and maximize throughput.
Each process area is designed with appropriate environmental controls, utility infrastructure, and safety systems. Wet process areas require chemical containment and exhaust, while high-temperature diffusion and firing zones need thermal management and specialized ventilation. Metallization areas demand cleanroom conditions for consistent screen-printing quality.

We design ISO-classified cleanrooms for metallization, PECVD, and other critical process areas with temperature, humidity, and air quality controls that meet process specifications.
Air filtration and contamination control address both particle counts and chemical contaminants that can affect cell performance. Process exhaust systems safely remove process byproducts while maintaining the environmental integrity of adjacent clean zones. Temperature and humidity control ensures process stability across seasonal variations and equipment heat loads.
