讲座题目：Third-generation solar cells: fundamentals and scale-up
摘要：Third generation solar cells such as dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs) are attractive alternatives to conventional commercial solar cells due to the low cost materials and manufacturing processes, however, they do not yet have the maturity level for commercialization and several challenges remain to be solved, for example, the relatively low efficiency and stability. In this work, the fundamental concepts related to these cells, the components that are used in the fabrication process, and the main processes that govern their functioning are presented. Different types of semiconductor, dye and electrolyte for DSSCs are reviewed and actual architectures for PSCs are discussed.Advanced electrochemical characterization techniques such as electrochemical impedance spectroscopy (EIS), intensity-modulated photovoltage spectroscopy (IMVS), and intensity-modulated photocurrent intensity (IMPS) are explained, and examples of their application to the study of the performance of DSSCs are provided. Other topics that will be addressed are the design optimization and aspects of solar cell scale-up, including challenges such as the synthesis of nanomaterials and paste preparation in large scale, the design and configuration of the mini-modules, the optimization of the active area and, the development of reproducible methods of sealing.
