1. Towards a Circular Economy with Environmental Product Policy : Considering dynamics in closing and slowing material loops for lighting products
Abstract : A Circular Economy (CE) can help to achieve the sustainable development goal of responsible consumption and production. Product policies, in turn, can support CE objectives by promoting reuse of products, recycling of materials, and providing ecodesign incentives for more durable products. READ MORE

2. Trading Off between Flexibility and Product Platform Constraints for Effective Technology Introduction
Abstract : Developing product platforms is an established method of reducing internal variety costs while delivering variety to customers. A critical aspect of a platform, that is expected to be used and extended for many years, is the ability to introduce new technologies and solutions effectively. READ MORE

3. Toward resilient product-based service supply chains
Abstract : Circular economies represent a step toward breaking the linear production model in supply chains. As drivers of enhanced circularity, product-based service (PBS) offerings extend and/or intensify the utilization period of products and thus decelerate the flow of resources. READ MORE

4. Design and Stability of Cu(In,Ga)Se2-Based Solar Cell Modules
Abstract : Cu(In,Ga)Se2 (CIGS) is one of the most promising semiconductor compounds for large-scale production of efficient, low-cost thin film solar cells, and several research institutes have announced their plans for CIGS production lines. But for the CIGS technology to become a commercial success, a number of issues concerning manufacturability, product definition, and long-term stability require further attention. READ MORE

5. Carrier Lifetime Relevant Deep Levels in SiC
Abstract : Silicon carbide (SiC) is currently under development for high power bipolar devices such as insulated gate bipolar transistors (IGBTs). A major issue for these devices is the charge carrier lifetime, which, in the absence of structural defects such as dislocations, is influenced by point defects and their associated deep levels.
