Plus de détailsOrganic-inorganic perovskites were fabricated through a one-step procedure with different levels of hydration water in precursor solutions. The optical properties of CH3NH3PbI3 films were investigated through spectroscopic ellipsometry and photoluminescence measurements. With the measured optical constants, the efficiency limit of perovskite solar cells is predicted with a detailed balance model.
Plus de détailsA BN interphase has been deposited, by isothermal/isobaric chemical vapor infiltration (ICVI) from BF 3 ─NH 3, within a preform made from ex‐polycarbosilane (ex‐PCS) fibers, at about 1000°C.In a second step, the BN‐treated preform was densified with SiC deposited from CH 3 SiCl 3 ─H 2 at about the same temperature. From a thermodynamic standpoint, ex‐PCS fibers could be regarded ...
