混合聚合物/纳米颗粒太阳能电池具有由半导体无机纳米颗粒和半导体共轭聚合物组成的光捕获层。它们具有提供高功率转换效率（PCE）的潜力。然而，这些太阳能电池报告的PCE值目前没有预期的那么高。本文从胶体的角度综述了目前制备聚合物/纳米粒子杂化太阳能电池的主要方法。PCE的数据为2005-2011年期间的混合聚合物/纳米粒子太阳能电池，并从聚合物/富勒烯电池相比。混合聚合物/纳米颗粒太阳能电池PCE值相对较低的关键原因是纳米颗粒表面不受控制的聚集和残留的绝缘配体。在曼彻斯特研究的两个混合聚合物/纳米粒子系统被认为是在其中的发病聚集和其对复合膜形态的影响进行了研究，从胶体的角度来看。它的结论是，阶跃变化的方法，需要增加的混合聚合物/纳米粒子太阳能电池的PCE，并将它们推向广泛的商业化所需的10%的值。一系列的纳米粒子，有可能在更长期的太瓦太阳能生产的应用潜力进行了讨论。
Hybrid polymer/nanoparticle solar cells have a light harvesting layer composed of semiconducting inorganic nanoparticles and a semiconducting conjugated polymer. They have potential to give high power conversion efficiencies (PCE). However, the PCE values reported for these solar cells are not currently as high as anticipated. This article reviews the main methods currently used for preparing hybrid polymer/nanoparticle solar cells from the colloid perspective. PCE data for the period of 2005–2011 are presented for hybrid polymer/nanoparticle solar cells and compared to those from polymer/fullerene cells. The key reasons for the relatively low PCE values for hybrid polymer/nanoparticle solar cells are uncontrolled aggregation and residual insulating ligands at the nanoparticle surface. Two hybrid polymer/nanoparticle systems studied at Manchester are considered in which the onset of aggregation and its affect on composite film morphology were studied from the colloidal perspective. It is concluded that step-change approaches are required to increase the PCEs of hybrid polymer/nanoparticle solar cells and move them toward the 10% value required for widespread commercialisation. A range of nanoparticles that have potential for application in possible longer term terawatt solar energy production are discussed.
