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

可以从太阳能电池中提取的电能（电压）与吸收的光子数量(N)、将这些光子转换为电荷的量子效率（QE）成正比，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。该提案寻求通过亚酞菁（subPc）晶体单独或与其他亚酞菁或酞菁晶体混合的广谱吸收阳光来增加N。同时，为了最大限度地提高QE，我们还将研究新子粒子在晶体内的超分子排列。

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.
