中文摘要：

能源问题是目前最为关注的焦点之一,随着社会的进步和工业的发展,地球上已探明可使用的化学燃料能源,包括石油、天然气和煤等,日趋枯竭。太阳能的利用已引起各国的重视。光伏器件是太阳能利用的最为重要的手段之一,有机太阳电池在此类器件中将承担极其重要的角色。但低的光电转换效率是阻碍其产业化的瓶颈。为此简要综述了提高有机太阳能电池能量转化效率的两个思路,并指出了有待解决的问题。

英文摘要：

Energy is most important issue in the world now because the chemical energy（oil,natural gas,coal et al） is on the edge of depleting.Many Countries are now paying attention to the use of sun power.Photovoltaic device is the most important way to make use of sun energy.Organic solar cell is one promising kind of photovoltaic device,though it＇s low power conversion efficiency hampers its commercialization.This paper briefly reviewed two ways to improve the power conversion efficiency of organic solar cells and pointed out the unsolved problems.
