Subphthalocyanines to achieve broad spectral absorption and produce a photocurrent in an organic solar cell

太阳能电池所能吸收的电能(电压)与吸收的光子数(N)成正比，也就是将这些光子转化为电荷的量子效率(QE)，与光子的波长成反比。因此，为了增加产生的电压量，需要增加N和/或QE或减少吸收光子的波长。这一建议旨在通过亚酞菁(SubPc)晶体本身或作为其他亚酞菁或酞菁晶体的混合物对阳光的广泛光谱吸收来增加氮。同时，为了最大限度地提高量子效率，我们将研究晶体中新的亚PCs的超分子排列。

The amount of electrical energy (voltage) which can be drawn from a solar cell is proportional to the number of photons absorbed (N), the quantum efficiency of converting those photons to electrical charge (QE) and inversely proportional to wavelength of the photons. Therefore in order to increase the amount of voltage produced, an increase in N and/or QE or a reduction in the wavelength of the absorbed photons is needed. This proposal seeks to increase N through broad spectral absorption of sunlight by subphthalocyanine (subPc) crystals either on their own or as a mixture with other subphthalocyanine or phthalocyanine crystals. At the same time, the supramolecular arrangement of the new subPcs within the crystal will be studied in order to maximize QE.
