Polymer solar cells have received a lot of attention because of their potential for flexible solar modules. This expectation can be attributed to the intrinsic nature of polymers. Single-junction polymer solar cells have recently shown an encouraging power conversion efficiency. However, multi-junction (tandem) polymer solar cells have been gradually approached to overcome the fundamental limitation of organic semiconductors with highly dispersive charge transport characteristics. To fabricate tandem polymer solar cells, each sub-cell should be separated by an interconnection layer that plays a core role in charge transport among sub-cells. To date, very limited kinds of materials have been reported on the interconnection layers. Recently, our group has successfully demonstrated organic/inorganic hybrid charge-collecting layers for polymer solar cells. This presentation discusses new types of tandem polymer solar cells by employing organic/inorganic hybrid interconnection layers.
