Different Device Architectures for Bulk-Heterojunction Solar Cells

We report different solar cell designs which allow a simple electrical connection of subsequent devices deposited on the same substrate. By arranging the so-called standard and inverted solar cell architectures next to each other, a serial connection of the two devices can easily be realized by a single compound electrode. In this work, we tested different interfacial layer materials, such as p...

Bulk Heterojunction Solar Cells — Opportunities and Challenges

Device model for the operation of polymer/fullerene bulk heterojunction solar cells

We have developed a numerical device model that consistently describes the current-voltage characteristics of polymer:fullerene bulk heterojunction solar cells. Bimolecular recombination and a temperatureand fielddependent generation mechanism of free charges are incorporated. It is demonstrated that in poly 2-methoxy53 ,7 -dimethyloctyloxy -p-phenylene vinylene OC1C10-PPVand 6,6 -phenyl C61-bu...

Hybrid morphology dependence of CdTe:CdSe bulk-heterojunction solar cells

A nanocrystal thin-film solar cell operating on an exciton splitting pattern requires a highly efficient separation of electron-hole pairs and transportation of separated charges. A hybrid bulk-heterojunction (HBH) nanostructure providing a large contact area and interpenetrated charge channels is favorable to an inorganic nanocrystal solar cell with high performance. For this freshly appeared ...
