来自玛丽大学和伦敦帝国学院的科学家团队最近进行了一项研究进入太阳能电池的性能，发现音乐中的声音振动可以增加太阳能电池的功率输出。

对于流行音乐和岩石的粉丝来说，这两个特定的类型是由于他们的高音调高达40％，这两种特定的流派增强了能量。音乐与较低的音调声音，如古典音乐，虽然仍然能够增加单元格输出，但并不像成功。

研究人员越来越了数十亿杆（纳米棒），其由氧化锌制成。通过用活性聚合物覆盖它们，它们能够形成可以将阳光转化为电力的装置。

突破意味着通过在许多环境中发现的环境或背景噪声可以改善太阳能电池的效率。因此，太阳能可以用来为甚至更广泛的设计提供动力，例如太阳能笔记本电脑和空调单元，以及火车和公共汽车上的电子元件。

该研究发表于上个月在期刊先进材料中，发现即使是低至75分贝的声级，例如归因于办公室打印机或典型的路边噪声 - 可以显着提高测试太阳能电池性能。

Commenting on the findings, James Durrant, Professor of Photochemistry at Imperial’s Department of Chemistry said: “We thought the soundwaves, which produce random fluctuations, would cancel each other out and so didn’t expect to see any significant overall effect on the power output.

“The key for us was that not only that the random fluctuations from the sound didn’t cancel each other out, but also that some frequencies of sound seemed really to amplify the solar cell output – so that the increase in power was a remarkably big effect considering how little sound energy we put in.”

By playing music rather than dull flat sounds the team were able to explore the effect of different pitches, eventually discovering that efficiency was greater when they played pop and rock compared to classical music, with the solar cells responding better to higher pitched sounds.

本文的共同作者，玛丽大学史蒂夫·邓恩博士表示，发现是“一个真正令人兴奋的发展，表明类似的物理性质也可以提高光伏太阳能电池的性能。”

大多数现代商业太阳能电池均有效率10-20％。效率提高是太阳能产业与研发持续焦点的重要焦点。
