Abstract

In this paper, two techniques are used to experimentally improve the solar cells efficiency by coating the outer surface of the panels with oil and chlorophyll. Coating the outer glass of solar cell with small layer of oil improves the value of sunlight absorbed by panel and accordingly the efficiency of the panels dramatically increases due to high transmissivity of some types of oils, especially vacuum oils. In this experiment, four types of oils are examined such as vacuum oil, engine oil, abro oil used as a mineral oils and sunflower oil examined as a natural oil. During the experiment, it has been observed the efficiency of the solar cell panels that have been coated with vacuum oil (labovac oil) increased by 11.28% compared to the efficiency of the same panel before coating. Similarly, coating the outer surface of solar panel with 1.5 mm layer of chlorophyll improves the efficiency by 4.17% as chlorophyll absorb a wide range of sunlight falling on surface of the photovoltaic panel and thus increase its efficiency.

叶绿素和不同类型油包覆提高太阳能电池效率

本文采用两种技术，通过在太阳能电池板的外表面涂覆油和叶绿素来提高太阳能电池的效率。由于某些类型的油，特别是真空油具有较高的透过率，在太阳能电池的外玻璃上涂上一层小的油，可以提高太阳能电池板对阳光的吸收量，从而大大提高太阳能电池板的效率。本实验对真空油、发动机油、作为矿物油的葵花籽油、作为天然油的葵花籽油等四种油进行了检测。在实验中，观察到涂有真空油(labovac油)的太阳能电池板的效率比未涂有真空油的太阳能电池板的效率提高了11.28%。同样，在太阳能电池板的外表面涂上1.5 mm的叶绿素层，效率提高4.17%，这是因为叶绿素吸收了落在太阳能电池板表面的大范围太阳光，从而提高了太阳能电池板的效率。
