Highly Conductive and Broadband Transparent Zr-Doped In2O3 as Front Electrode for Solar Cells (vol 8, pg 1202, 2018)

In the paper [1], the reported values of the oxygen to total flow ratio, defined as r(O2) in %, should be multiplied by a factor of 3 ± 0.1, which corresponds to the correct calibration factor for the mass flow controllers. This correction should be applied consistently throughout the paper where the r(O2) (%) is mentioned. It is important to note that this correction does not change the conclusion of the article, and all the results presented remains valid

Effect of Salicylate on the Elasticity, Bending Stiffness, and Strength of SOPC Membranes

Salicylate is a small amphiphilic molecule which has diverse effects on membranes and membrane-mediated processes. We have utilized micropipette aspiration of giant unilamellar vesicles to determine salicylate's effects on lecithin membrane elasticity, bending rigidity, and strength. Salicylate effectively reduces the apparent area compressibility modulus and bending modulus of membranes in a dose-dependent manner at concentrations above 1 mM, but does not greatly alter the actual elastic compressibility modulus at the maximal tested concentration of 10 mM. The effect of salicylate on membrane strength was investigated using dynamic tension spectroscopy, which revealed that salicylate increases the frequency of spontaneous defect formation and lowers the energy barrier for unstable hole formation. The mechanical and dynamic tension experiments are consistent and support a picture in which salicylate disrupts membrane stability by decreasing membrane stiffness and membrane thickness. The tension-dependent partitioning of salicylate was utilized to calculate the molecular volume of salicylate in the membrane. The free energy of transfer for salicylate insertion into the membrane and the corresponding partition coefficient were also estimated, and indicated favorable salicylate-membrane interactions. The mechanical changes induced by salicylate may affect several biological processes, especially those associated with membrane curvature and permeability

Hybrid sequential deposition process for fully textured perovskite/silicon tandem solar cells

Tandem solar cells that feature a high-bandgap perovskite cell on top of a lower bandgap silicon cell have the potential to reach efficiencies > 30%. Here, we present a versatile hybrid deposition method that yields conformal perovskite cells directly on textured silicon bottom cells, a prerequisite to achieve highest photocurrents and hence efficiencies. Furthermore, this low-temperature evaporation/spin-coating 2-step method produces high-quality perovskite materials with different bandgaps, here varied in the range of 1.5 eV to 1.8 eV. This flexibility enables the fabrication of monolithic 2-terminal perovskite/textured Si tandems that feature high photocurrents of about 19.5 mA/cm(2)
