日益增长的能源需求和对能源转换的清洁技术的日益迫切的需求构成了我们时代最紧迫和最复杂的问题之一。热电，即直接将废热转化为电能，是一种基于长期存在的物理现象的有前途的技术，主要由于该过程的效率低，其潜力尚未充分开发。为了提高热电性能，物理学家、材料科学家和工程师正在做出巨大的努力，其主要目的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器件。在这份路线图中，概述了意大利研究界在优化某些热电材料的成分和形态以及热电和混合热电/光伏器件设计方面获得的最新实验和计算结果。
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.
