NettetThen, the deposited Cu ink was sintered by an intense pulsed light (IPL) system. The sintering effects were investigated with different sintering conditions including pulse energy and pulse duration. The resulting electrical resistivity was 94.1uΩ·cm which is about fifty times as high as that of bulk copper. The high resistivity may be mainly ... Nettet22. mar. 2016 · Perovskite solar cells utilizing a two-step deposited CH3NH3PbI3 thin film were rapidly sintered using an intense pulsed light source. For the first time, a heat treatment has shown the capability of sintering methylammonium lead iodide perovskite and creating large crystal sizes approaching 1 μm without sacrificing surface coverage.
Intense Pulsed Light Sintering of CH3NH3PbI3 Solar Cells
NettetIn intense pulsed light sintering (IPL), visible (400–700 nm), large-area (up to nine square inches or greater optical foot-print) pulsed light from a xenon lamp is absorbed and con-verted into heat by nanoparticles deposited on a substrate, resulting in densification of the nanoparticles (figure 1(a)). NettetIn 2015, Secor 28 et al. sintered a graphene-based ink printed on the flexible substrate PET by intense pulsed light. They produced inkjet-printable graphene-based inks with high concentrations of up to 20 mg ml −1 and realized excellent conductivity of 25 000 S m −1 after one printing pass with pulsed light sintering. oak grove mesothelioma lawyer vimeo
