设计能够过滤电磁光谱并在可见光谱的UV和高能部分明显吸收的新型聚合物对于半透明太阳能电池的发展至关重要。在此，我们报告了三种新聚合物的合成和光谱，电化学和物理特性，即（i）聚（三聚对苯二酸酯），（ii）聚[三聚对苯二酸酯-co- 3-（2-吡啶基）-5，6-二苯基-1，2，4-三嗪-p，p′-二磺酰胺]，和（iii）聚（5-羟基吲哚-2-羧酸酯），可能显示出作为半透明太阳能电池材料的前景。电子给体聚合物聚对苯二甲酸三酯的能带隙、折射率、介电常数和光学电导率分别为2.92 eV、1.56、2.44和2.43 × 104 S cm-1。合成的电子受体聚合物显示出相对较高的折射率，介电常数和光学电导率。一个直接允许的过渡的存在下，确认之间的聚合物的分子间的能带。这些聚合物表现出相对较高的能隙和较深的HOMO能级，使它们成为紫外区和可见光区高能部分光子的强吸收体。由于HOMO和LUMO能级的紧密匹配，合成的供体和受体相对于P3 HT和富勒烯表现良好。随着进一步的发展，聚合物可以用作半透明太阳能电池的活性层。
The design of new polymers able to filter the electromagnetic spectrum and absorb distinctly in the UV and high-energy part of visible spectrum is crucial for the development of semi-transparent solar cells. Herein, we report on the synthesis and spectroscopic, electrochemical, and photophysical characteristics of three new polymers, namely (i) Poly(triamterene-co-terephthalate), (ii) Poly[triamterene-co- 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-p,p′-disulfonamide], and (iii) Poly(5-hydroxyindole-2-carboxylate) that might show promise as materials for semi-transparent solar cells. The energy band gap, refractive index, dielectric constant, and optical conductivity of the electron donor polymer, poly(triamterene-co-terephthalate), were determined to be 2.92 eV, 1.56, 2.44 and 2.43 × 104 S cm−1, respectively. The synthesized electron acceptor polymers showed a relatively high refractive index, dielectric constant, and optical conductivity. The presence of a direct allowed transition was confirmed between intermolecular energy bands of the polymers. The polymers showed relatively high energy gap and deep HOMO levels, making them strong absorbers of photons in the UV region and high energy part of the visible region. The synthesized donor and acceptors performed well relative to P3HT and fullerenes due to the close match of the HOMO and LUMO levels. With further development, the polymers could be viable for use as the active layers of semi-transparent solar cells.
