(731a) Multiple Criteria Productivity Analysis Applied to Perovskite Solar Devices from Lab to Factory Production

The process of understanding the consequences and impacts of industrial scale manufacturing decisions is highly time consuming, requires multiple areas of expertise and a variety of different, and occasionally conflicting, philosophies. Multiple Criteria Productivity Analysis consolidates a variety of methodologies to create a single holistic method for assessing the time, cost and environmental impact of manufacturing decisions. MCPA is an approach which uses life cycle inventory data in combination with activity-based analysis to understand the relationship between output productivity as a measure of output per unit time and environmental productivity as a measure of output per unit environmental impact. A tool has been created in conjunction with the development of the MCPA methodology. Significant advances have been made in understanding the requirements of and relationship to each of the distinctive data subsets which exist, creating a rich data flow from the environmental impact of raw materials to the capital and operational costs of machines and tools through to the time taken to undertake each individual activity. The MCPA method is herein demonstrated for the production of perovskite devices in a university lab environment and a full scale production scenario with detailed results on the trade-offs between increased output productivity on environmental productivity within the film deposition process based industry, providing the evidence for holistic industrial decision making alongside product design focussed outcomes.
