Recently, Dr. Tan Furui, a young teacher at the Henan Provincial Key Laboratory of Photovoltaic Materials, has made significant progress in the research of lead sulfide (PbS) quantum dot thin film solar cells. The research results have been published in the internationally renowned magazine Advanced Energy Materials (DOI: 10.1002/aenm). .201400512) (SCI Impact Factor 14.385) and Journal of Materials Chemistry A (2014, 2, 14502-14510) (SCI Impact Factor 6.626). The key technologies in the research results have applied for national invention patents.
In recent years, the Key Laboratory of Photovoltaic Materials of Henan University has been devoted to the basic research and development of new types of solar cells such as organic thin film solar cells, perovskite materials solar cells and quantum dot thin film solar cells. Dr. Tan Furui and others have synthesized composite nanomaterials with high-efficiency charge transfer properties to build optimized heterostructures of composites, enhanced charge transfer properties at the heterojunction interface, and greatly improved quantum dot thin film solar cells and organic-inorganic composite thin film batteries. The photoelectric conversion efficiency.
The splitting efficiency of photoexcited exciton in traditional PbS QD cells is not high. Physically blending PbS QDs with branched CdSe nanomaterials with high charge transfer efficiency to form network hybrid heterojunctions is effective. The splitting and charge transfer properties of excitons at the interface are improved. The core-shell structure of CdSe/PbS nano-tetrahedron is combined with organic semiconductor P3HT to improve the exciton splitting and electron transport performance. The developed composite thin film battery has higher performance. The photovoltaic performance.
Silicon-based solar cells currently have a market share of 90%, but the high cost and pollution problems are a major bottleneck. Once new solar cells achieve breakthroughs in efficiency, cost, and longevity, they will bring about revolutionary changes in the photovoltaic industry and tremendous commercial value.
Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce
dyes,pesticides, pharmaceuticals, resins, Additives, plasticizers and other intermediates. Because it was originally used to make
dyes, also known as dye intermediates.now it is referred to the various intermediates obtained during organic synthesis.
