Correlation of Interfacial Composition and Bulk Morphology to Device Performance in Organic Bulk Heterojunction Solar Cells*

摘要

Third generation thin film photovoltaics,including inorganic- organic hybrids,and organic photovoltaics (OPV),are promising emerging technologies for the preparation of large-scale,mechanically robust and inexpensive solar cells. Many of these technologies rely on solution processible materials that can be deposited by low-cost,low- waste technologies (i.e.,printing),which are amenable to large-area and continuous production methods,capturing significant economies of scale when compared to conventional silicon solar cell fabrication methods. The critical technology barriers that remain for thin film photovoltaic technologies are modest efficiency and limited performance life. These challenges must be overcome to realize the promise of these new technologies with widespread deployment of solar energy harvesting devices.
