mV的开路电压，光电转化效率低得让人都不好意思提。,OPV,发展历程,9,此后二十多年间，有机太阳能电池领域内创新不多，所有报道的器件之结构都类似于1958年版，只不过是在两个功函数不同的电极之间换用各种有机半导体材料。1986年，行业内出现了一个里程碑式的突破。实现这个突破的是位华人，柯达公司的邓青云博士。这个时代的有机太阳能电池所采用的有机材料，主要还是具有高可见光吸收效率的有机染料。,（,1%,）！,OPV,发展历程,10,OPV,发展历程,美国加州伯克利分校科学家在,2002,年利用塑料纳米技术研制出第一代塑料太阳能电池，可以安装在一系列便携式设备及可穿戴式电子设备上。提供,0,7V,的电压。,价格低、易成型，通过化学修饰调控性能。,11,有机太阳电池光电转换过程：,1),入射光在有机聚合物中的吸收；,2),产生激子；,3),激子向给体,/,受体界面的扩散；,4),激子在给体,/,受体界面上的电荷分离，产生给体,HOMO,能级上的空穴和受体,LUMO,上的电子；,OPV,实现原理,12,HOMO,HOMO,LUMO,LUMO,下电极,上电极,给体,受体,h,真空,吸收光子产生激子,(,电子空穴对,),激子在给体受体界面分离,自由电子和空穴传输并被两极收集,电荷产生，传输和收集,有机太阳能电池原理,。,有机电池吸收光以后首先激发的是激子，激子由电子和空穴成对组成，呈中性，对电池收集电流并没有贡献。最关键的是产生的激子向给体,/,受体界面扩散，在界面势场的作用下发生电子和空穴的分离，一旦分离以后产生的载流子才对电池有贡献！,13,太阳能电池,能量转换效率,(PCE),：,太阳电池受光面积的最大输出功率（,Pmax,）与入射的太阳光能量密度（,Plight,）的百分比。,R,(JV),max,JscVoc,R(0,),14,有机薄膜制作方法,(,膜厚由转速、溶剂、组成成分和浓度决定,),刮刀刀片,丝网印刷,旋涂,有机太阳能电池制作方法,15,优点,成本低,质量轻,材料来源广泛,制备工艺简单,可做在柔性衬底上,可大面积生产,材料的光及电特性可调整,缺点,效率低,寿命短,有机太阳能电池优缺点,16,有机聚合物太阳能电池的应用前景可表现在：,可穿戴光伏设备（突出的柔性特点，环保特性），,楼宇的玻璃幕墙（需要一定量光透过，又能利用剩余太阳能资源），,条件比较极端的应用场景（高温，弱光等），,便携式小型太阳能设备（材料轻薄）,仿生学应用（例如自然界中光合作用第一步光反应的能量转换效率高达,42%,，可以人工合成这种酶，用以大幅度提高光伏器件效率）,发展前景,17,行业资讯,18,有机光伏薄膜领域的行业领先企业,Heliatek
