    Earth-abundant Cu2BaSnS4 (CBTS) thin films exhibit the optoelectronic and defect properties suitable as an absorber for the top cell of tandem photovoltaic solar cell devices. Oxygenated CdS (CdS:O) buffers enable high VOC's of 0.9–1.1 V in CBTS thin-film solar cells by minimizing interface recombination.

    A duck-shaped triboelectric nanogenerator (TENG) for effectively scavenging energy from random and low- frequency water waves is presented. The design of the TENG incorporates the freestanding rolling mode and the pitch motion of a duck-shaped structure generated by incident waves. The newly designed TENG is promising for building a network of generators to harvest existing blue energy in oceans, lakes, and rivers.

    Low-index nanoporous materials that exploit optimized chemistries and self-assembly processes are demonstrated, with over ≈98% of transmission efficiency and angle-/polarization-insensitivity up to ±40° across a broad solar spectrum range. Applying such nanoporous anti-reflection coatings onto the optical elements in a concentration photovoltaic platform leads to a relative improvement of ≈8% in photovoltaic conversion efficiencies.

  5. Electrochemical Stiffness Changes in Lithium Manganese Oxide Electrodes

    Electrochemical stiffness in LiMn2O4 reveals the dominating mechanical forces on the composite electrode during Li+ ion intercalation. The electrode experiences stiffness due to kinetic barriers at the surface, phase transitions, Coulombic repulsions between Li+ ions in the material, and lattice relaxation. Stiffness reveals distinct mechanical deformations during delithiation versus lithiation.
