Dual Layer OSC Dual layer OSCs are a significant upgrade to single layer, as an additional polymer layer is added between the electrodes. The two layers are classified as the electron donor and acceptor layer, which is …
Organic solar cells can be classified as single layer, bilayer, bulk heterojunction, and ordered heterojunction configurations. Conjugated polymers are typically used as donor materials for harvesting sunlight; fullerene derivatives and inorganic semiconductor materials such as CdSe, TiO 2, ZnO are used as acceptor materials.
The power conversion efficiencies for both the single-layer devices fabricated using the imidazolin-5-one molecules, however, is low compared to that reported for other organic solar cells. Besides the fact that single-layer devices inherently have lower efficiency, low carrier mobility, poor interface morphology and lack of optimisation of …
