Web8 Feb 2024 · Planar and three-dimensionally structured p-Si devices, consisting of an electrodeposited Co–P catalyst on arrays of Si microwires or Si micropyramids, were used as photocathodes for solar-driven hydrogen evolution in 0.50 M H2SO4(aq) to assess the effects of electrode structuring on parasitic absorption by the catalyst. Without the use of …
Efficient energy transfer mitigates parasitic light absorption in ...
WebParasitic radiation absorption by impurities located in transparent polycrystalline ceramic hosts may significantly impair their functioning. At least two classes of impurity which can act as parasitic absorbers were encountered: transition or rare-earth metal cations and neutral species (molecules or atoms) trapped in lattice void spaces. WebAbstract. A solar-driven photoelectrochemical cell provides a promising approach to enable the large-scale conversion and storage of solar energy, but requires the use of Earth … richards thomas brecon
