摘要：目前的太阳能电池，根据所用的材料主要可以分为两大类：一是无机半导体太阳能电池，二是有机/聚合物半导体太阳能电池。现在商业化的太阳能电池主要是无机太阳能电池，但是其成本太高，而且无机材料有不可降解的毒性和不易柔性加工的缺点。因此，开发有机/聚合物太阳能电池是很有必要的。有机/聚合物器件具有柔性、质轻、易制备等优点。聚合物更表现出了高的开路电压（可大于2V）及工艺简单的优点，而且价廉、易大量大面地生产。聚苯撑乙烯撑系列衍生物就是一种能用于聚合物太阳能电池的电子给体物质。本文就对该物质以及该物质所构成的光伏器件的光伏性能展开研究。

Polyphenylene vinylene derivatives photovoltaic properties

Abstract: According to the materials used, the nowadays solar cells can be divided into two types. One is inorganic semiconductor solar cells, the other is organic / polymer semiconductor solar cells. Although the commercialization of solar cells is mainly based on inorganic solar cells, it is still limited to expand its application due to their high cost, non-degradable toxicity and non-flexible fabrication properties. Therefore, the development of organic / polymer solar cells is very necessary. The advantages of organic/polymer photovoltaic devices are flexibility, lightweight and easy fabrication. With its simple technology and low cost, polymer solar cells also demonstrated the advantages that it can provide a high open-circuit voltage (voltage can be more than 2V) and can be put into mass production. Polyphenylene vinylene derivatives can be used as donors for polymer solar cells. This paper is about the investigation of its photovoltaic performance.

Keywords：Polymer solar cells; Polyphenylene vinylene Derivatives; PV performance
