Bulk Heterojunction Organic Solar Cells: Working Principles and Power Conversion Efficiencies

Bulk heterojunction solar cells are a promising low-cost photovoltaic technology. This chapter discusses the efficiency potential, the role of nanomorphology and approaches to increase the power conversion efficiency of bulk heterojunction solar cells. The stacking of devices on top of each other – constructing the so-called tandem cell – appears to be one of the best ways to reach the power conversion efficiencies necessary for the large-scale commercialization of this technology.
