The implementation of water splitting systems, powered by sustainable energy resources, appears to be an attractive strategy for producing high‐purity H2 in the absence of the release of carbon dioxide (CO2). However, the high cost, impractical operating conditions, and unsatisfactory efficiency and stability of conventional methods restrain their large‐scale development. Seawater covers 70% of the...
Hydrogen production from steam or autothermal alcohol reforming has been widely studied, but these methods require high temperatures and emit CO2. Here, we present a new strategy for the simultaneous room-temperature production of hydrogen and other chemicals without the emission of CO2, via the photoelectrochemical reforming of biomass-derived alcohols. The measured hydrogen quantum efficiencies...
The defect scatter interval (St) of a-Si:H/c-Si interface and void concentration (Cv) of a-Si:H were analyzed by Spectroscopic Ellipsometry (SE). The passivation performance of a-Si:H layers in SHJ solar cells was not only affected by the conductivity, but more importantly, it was strongly governed by the hydrogen content (CH) in a-Si:H layers. In addition, the microstructure deduced from SE was in...
