Study on Carbazole-like Polymer Solar Cell Materials

Abstract

<p>With the development of modern industry, the global energy crisis and air pollution problems become increasingly prominent. Solar energy has emerged as an ideal renewable energy by many countries’ attention. Solar cells are the most promising use of solar energy in the kind of concern. Compared with inorganic solar cells, polymer solar cells performance is more excellent and carbazole polymer materials with rigid fused ring structure, intramolecular electron transfer, good transport and easy to introduce a variety of multi-functional groups into the carbazole. The advantages of the ring in the field of solar cell materials show a wide range of potential applications. This paper describes the principles of polymer solar cells and several common donor materials. The precursors of carbazole polymers were designed and synthesized, and their structures were characterized. </p>
