Recent Development and Advance of Solar Photovoltaic Materials and Photothermal Conversion Materials

重点探讨了太阳能光电、光热转换技术领域的材料研究现状与发展,主要包括光伏电池半导体材料和太阳光谱选择性吸收涂层光学材料膜系。太阳电池材料的关键问题还是成本与光电转换效率,钙钛矿太阳电池的研究成为光伏电池新的研究热点。太阳光谱选择性吸收涂层是太阳能光热利用领域的核心材料技术之一。近年来,太阳能的中高温热利用,尤其是聚焦热发电技术,作为与光伏发电平行的另一种主流太阳能发电方式,成为人们日益关注的焦点。另外,还阐述了中高温太阳光谱选择性吸收涂层在国内外的研究成果和最新进展。

The research status and advance of solar photovoltaic materials and photothermal conversion materials, which mean semiconductor solar cell materials and solar spectral selective absorbing coatings, were reviewed. The main problems of solar cell materials are cost and photoelectric conversion efficiency （PCE）. The investigation of perovskite solar cell becomes a new research hotspot. On the other hand, solar selective absorbing coating is one of the key material technologies of solar thermal utilization. In recent years, medium-high temperature heat utilization of solar energy, especially the technology for concentrated solar power （CSP） as another mainstream of solar energy generation, is becoming a focusing in parallel with photovoltaic power generation. Thus this paper also talks about the research results and recent development of high temperature solar selective absorbing coatings as an important content.
