Environmental Control

Definition

Environmental control refers to the management and regulation of environmental conditions to ensure optimal performance and stability in manufacturing processes, particularly in roll-to-roll processing for large-scale fabrication. This involves maintaining parameters like temperature, humidity, and cleanliness, which are crucial for the quality and efficiency of organic photovoltaic production. Proper environmental control helps minimize defects, enhance product uniformity, and ensure safety during fabrication.
