Size Effects of MoS2 on Hydrogen and Oxygen Evolution Reaction

DOI: 10.33961/jecst.2021.00710 Authors: Gyawali Ghanashyam, Hae Kyung Jeong Abstract: Molybdenum disulfide (MoS2) has been widely used as a catalyst for the bifunctional activities of hydrogen and oxygen evolution reactions (HER and OER). Here, we investigated size...

Extreme sensitivity of dye solar cells to UV‐induced degradation

DOI: 10.1002/ese3.810 Authors: Aapo Poskela, Kati Miettunen, Armi Tiihonen, Peter D. Lund Abstract: Abstract Present practice to avoid harmful effects of UV light on dye solar cells (DSC) is to use a UV filter. However, we show here that a standard 400 nm UV cutoff...
