太阳能高效光伏热电-复合发电技术现状与展望

Status and Prospect of Efficient PV-TE Hybrid Power Generation Technology

能源需求增加和环境污染问题日益严峻,能源结构转型是实现全球可持续发展的必然趋势。太阳能发电得益于其资源丰富、分布广泛、洁净无污染等优点而成为新能源利用的首选,太阳能发电包括太阳能光伏发电(PV)和太阳能光热发电(TE)2种,将光伏电池和热电材料互补集成,建立光伏-热电(PV-TE)复合发电系统成为研究重点。文章简要介绍PV-TE复合发电工作原理,总结近年来国内外PV-TE领域研究现状,包括复合发电方式具体存在的一些关键问题,并对未来发展方向做出展望。

With the increase in energy consumption demand and the increasingly serious environmental pollution problems,energy transition is an inevitable trend to achieve global sustainable development.Solar power generation has become the first choice for new energy utilization due to its abundant resources,wide distribution,clean and pollution-free and many other advantages.Solar power generation includes two types of solar photovoltaic power generation(PV)and solar thermal power generation.Complementary integration with thermoelectric materials to establish a photovoltaic-thermoelectric(PV-TE)composite power generation system has become the focus of research by scholars at home and abroad.This paper introduces the working principle of PV-TE hybrid power generation,and summarizes the research status of PV-TE field at home and abroad in recent years,including some key problems in hybrid power generation methods.It also puts forward the prospects for possible future development directions.transition and upgrading.This paper is to conclude the development foundation to build China’s central energy and chemical enterprises into world-class onesfrom the aspects of serving economic and social needs,value creation,operation management,resource allocation,innovation drive and sustainable development,find out the real gap with world-class standards in the four capabilities of value creation,operation management,resource allocation and innovation drive,and put forward basic route to build world-class energy and chemical enterprisesthrough creating new situation,establishing new layout,strengthening new driving force,expanding into new market territory,carving a new path,taking on new tasks,cultivating new blood,nurturing new inner cores and forging new advantages.
