AbstractA highly efficient, low-cost and environmentally friendly photocathode with long-term stability is the goal of practical solar hydrogen evolution applications. Here, we found that the Cu3BiS3 film-based photocathode meets the abovementioned requirements. The Cu3BiS3-based photocathode presents a remarkable onset potential over 0.9 VRHE with excellent photoelectrochemical current densities (~7 mA/cm2 under 0 VRHE) and appreciable 10-hour long-term stability in neutral water solutions. This high onset potential of the Cu3BiS3-based photocathode directly results in a good unbiased operating photocurrent of ~1.6 mA/cm2 assisted by the BiVO4 photoanode. A tandem device of Cu3BiS3-BiVO4 with an unbiased solar-to-hydrogen conversion efficiency of 2.04% is presented. This tandem device also presents high stability over 20 hours. Ultimately, a 5 × 5 cm2 large Cu3BiS3-BiVO4 tandem device module is fabricated for standalone overall solar water splitting with a long-term stability of 60 hours.

Distribution of flightless insect lineages often help us to identify the areas of long-term stability which serve as biodiversity hotspots. In this paper we taxonomically revise the wingless click-beetle genus Neodima Schimmel & Platia, 1992 endemic to the mountainous regions of Sichuan, China. Neodima sichuanensis Schimmel & Platia, 1992 and N. cechovskyi Schimmel, 1998 are redescribed, and N. belousovi Prosvirov & Kundrata sp. nov. is described as new for science. The distribution and morphological diversity of Neodima is discussed, main diagnostic characters for all species are figured, and an identification key to the species of this genus is provided. Mouthparts as well as female pregenital segments and genitalia are described and figured for the first time for this genus. Further, we compare Neodima to morphologically similar genera, and discuss its systematic position within Dimini.
