Thermal-Driven Phase Separation of Double-Cable Polymers Enables Efficient Single-Component Organic Solar Cells

Directed self-assembly of viologen-based 2D semiconductors with intrinsic UV–SWIR photoresponse after photo/thermo activation

“…This range far from covers the whole solar spectrum (∼295-2500 nm), resulting in limited energy conversion fields of Si-based solar cells 2,8 . Constructing multiple blend systems or multi-junction device structures was demonstrated to be effect methods to fully utilize the solar radiation, but complexity, manufacture cost, and sometimes stability of the device should be concerned before stepping into the market [9][10][11] . The above issues for both photodetection and solar energy conversion devices are promisingly avoided, if a single semiconductor material with a photoresponsive range covering the entire UV-SWIR region is applied 10,12 .…”

“…Constructing multiple blend systems or multi-junction device structures was demonstrated to be effect methods to fully utilize the solar radiation, but complexity, manufacture cost, and sometimes stability of the device should be concerned before stepping into the market [9][10][11] . The above issues for both photodetection and solar energy conversion devices are promisingly avoided, if a single semiconductor material with a photoresponsive range covering the entire UV-SWIR region is applied 10,12 . As reported, some singlecomponent inorganic photoelectronic semiconductors showed strikingly wide detection ranges, for example, the photoresponse range of SnTe covers 254-4650 nm 13 .…”

“…However, practical application of them is still greatly limited by material rigidity, as well as complex and expensive manufacturing processes 14,15 . Organic-based photoelectronic semiconductors are characteristic of flexibility and facile preparation, but the observed up limit for photoresponse is about 1800 nm 10,12,[15][16][17][18] . It is still of importance to develop effective and general design methods for single-component organic-based semiconductors with intrinsic photoresponse in the entire UV-SWIR range.…”

Carbon Nano‐Onion and Zinc Oxide Composites as an Electron Transport Layer in Inverted Organic Solar Cells

“…The chemical strategies were also used to balanced photovoltaic parameters of the devices. [5.6] Increasing of molecular crystallinity of donor and acceptor materials may result in power conversion efficiency of over 16% …”

“…[5.6] Increasing of molecular crystallinity of donor and acceptor materials may result in power conversion efficiency of over 16%. [8] In the present study, we used ZnO due to its interesting physico-chemical properties with a band gap of 3.37 eV, [9] which is not effective for visible light-driven photocatalysis. [10,11] ZnO is characterized by a high exciton binding energy (60 meV) and piezoelectricity at room temperature.…”
