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

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.
