基于体异质结的方法进行了广泛的研究，从而导致高效率的光伏电池，但有机太阳能电池暴露于紫外线照射时，影响细胞的寿命下降。能源转换效率也较低时相比，其无机同行。图1显示了不同的研究小组在过去十年中所取得的效率。7.9%的效率是由solarmer公司实现的，这是由美国国家可再生能源实验室（NREL）认证。而黑格达到2.9%的量子效率，这表明在这一领域的快速发展超过十年。solarmer产生光伏商业产品使用的本体异质结的方法。 一家名叫Konarka公司成立于Heeger还生产塑胶电子和本体异质结太阳能电池。Konarka公司提供常规产品如传感器，便携式电池充电的PDA、手机和其他小型设备，微电子、移动电源、遥控电源，光伏建筑一体化。 Plextronics公司是另一家公司开发和销售预配制的油墨以及如何打印，这是室外的寿命进行了广泛的测试。使用这些产品的设备具有高寿命的顺序。 然而，聚合物光伏电池的效率是低的相比，基于硅的光伏器件。为了与其他可用的技术竞争，聚合物光伏电池的效率应增加至15%个寿命15-20年[太阳能，2009，1224 ]。Heeger提出的本体异质结的方法对聚合物太阳能电池领域的一个重大贡献，这在可再生能源中具有许多潜在的应用。
A wide range of research is carried out based on bulk heterojunction approach, which resulted in efficient photovoltaic cells; however organic solar cells degrade when exposed to ultraviolet light, which effects the life time of the cells. Energy conversion efficiency is also low when compared to its inorganic counterparts. Fig 1 shows the efficiency achieved by different research groups in the last decade. 7.9% efficiency is achieved by Solarmer Company, which is certified by National renewable energy laboratory (NREL). Whereas Heeger achieved a quantum efficiency of 2.9%, this indicates a rapid development in this field over a decade. Solarmer produce photovoltaic commercial products using bulk heterojunction approach.Another company named Konarka which is founded by Heeger also manufactures plastic electronics and solar cells with bulk heterojunction. Konarka offer conventional products like sensors, portable battery charging for PDA, mobiles and other small devices, microelectronics, portable power, remote power, building integrated photovoltaic.Plextronics is another company developing and selling pre-formulated inks as well as the know-how to print them, which are extensively tested for outdoor lifetime. Device using these products have high lifetimes of the order of years.However the efficiency of polymer photovoltaic cells is low when compared to the silicon based photovoltaic devices. In order to compete with other available technologies, the efficiency of polymer photovoltaic cells should be increased to 15% with a lifetime of 15-20 years [Solar energy, 2009, 1224]. Heeger made a significant contribution to polymer solar cells field by proposing the bulk Heterojunction approach, which has many potential applications in renewable energy.
