The increasing energy demand and the ever more pressing need for clean technologies of energy conversion pose one of the most urgent and complicated issues of our age. Thermoelectricity, namely the direct conversion of waste heat into electricity, is a promising technique based on a long-standing physical phenomenon, which still has not fully developed its potential, mainly due to the low efficiency of the process. In order to improve the thermoelectric performance, a huge effort is being made by physicists, materials scientists and engineers, with the primary aims of better understanding the fundamental issues ruling the improvement of the thermoelectric figure of merit, and finally building the most efficient thermoelectric devices. In this Roadmap an overview is given about the most recent experimental and computational results obtained within the Italian research community on the optimization of composition and morphology of some thermoelectric materials, as well as on the design of thermoelectric and hybrid thermoelectric/photovoltaic devices.
能源需求的不断增长和对清洁能源转换技术的迫切需求，是我们这个时代最紧迫和复杂的问题之一。热电转换，即将废热直接转化为电能，是一种基于长期存在的物理现象的有前途的技术，但由于该过程的效率较低，其潜力尚未得到充分发挥。为了提高热电性能，物理学家、材料科学家和工程师正在进行大量努力，主要目标是更好地理解改善热电优值的基本问题，并最终构建最有效的热电设备。在本路线图中，概述了意大利研究界在优化一些热电材料的组成和形态以及设计热电和混合热电/光伏器件方面所取得的最新实验和计算结果。
