Described are processes for enlarging the surface area of a polymer-based solar cell relative to a flat surface and/or for enlarging the active surface area of the organic semiconductor layer of the solar cell in relation to a flat surface. There is further described a polymer-based solar ...
Polymer-based solar cells have reached power conversion efficiencies of 5% in recent reports2, 3, 4, 5, 6. Deposition of organics by screen printing, doctor blading, inkjet printing, and spray deposition is possible because these materials can be made soluble. These techniques are required for ...

Recent progress in the development of polymer solar cells has improved power-conversion efficiencies from 3% to almost 9%. Based on semiconducting polymers, these solar cells are fabricated from solution-processing techniques and have unique prospects for achieving low-cost solar energy harvesting, owing...
Growing research efforts within the field of organic solar cells (OSCs) have led to rapid improvements in cell efficiency values over the last several years. The promise of lower manufacturing costs through roll-to-roll processes makes polymer-based solar cells particularly appealing [1], but a ...

Polymer solar cells, a highly innovative research area for the last decade until today, are currentlymaturing with respect to understanding of their fundamental processes of operation. The increasing interestof the scientific community is well reflected
Highly efficient polymer-based optoelectronic devices using PEDOT:PSS and a GO composite layer as a hole transport layer. We demonstrate highly efficient polymer light-emitting diodes (PLEDs), as well as polymer solar cells (PSCs), using a solution-processable poly(3,4-ethylen... JC Yu,JI ...
Polymer and organic solar cells degrade during illumination and in the dark. This is in contrast to photovoltaics based on inorganic semiconductors such as silicon. Long operational lifetimes of solar cell devices are required in real-life application and the understanding and alleviation of the degrad...
Here, we show that the open-circuit voltage of polymer solar cells constructed based on the structure of a low-bandgap polymer, PBDTTT, can be tuned, step by step, using different functional groups, to achieve values as high as 0.76V. This increased open-circuit voltage combined with a ...
