Narrow-Band-Gap Polymer Photovoltaic Materials Synthesis and Photovoltaic Research

Abstract:

In recent years, research of the narrow-band-gap polymer photovoltaic (PV) materials in the field of light-emitting diodes, field effect transistors, solar cells and sensors has made tremendous progress and its application becomes more widely. In order to obtain a better performance of the photovoltaic material, in the process of design the polymer, we must consider the spectral range, the energy gap, the balance between the LUMO and HOMO level. Through the analysis of the narrow-band-gap polymers, this paper described the synthesis of the photovoltaic material, and detailed analyzes its photovoltaic characteristics. This paper introduces the double bonds to combine DTBT receptors and different electron donor, to synthesize new narrow-band-gap polymer photovoltaic materials with photovoltaic properties.
