چکیده
Abstract It has been attempted to preferentially orientate Pb-I layers in two-dimensional (2D) organic-inorganic hybrid perovskite thin films (CH 3 2 ) NH )Pb I 7 perpendicular substrates only by thermal annealing after spin coating of a reagent solution for improvements the energy-conversion-efficiency solar cells. is found from X-ray diffraction measurements that ratio intensity (202) plane (060) becomes larger thermally annealed (50 °C–135 °C) samples. This indicates layer tends grow surface substrate. In particular, reached 8.2, which compared with 2.7 randomly oriented powder sample, sample prepared on SnO substrates. Such seem contribute tandem-type cells utilizing 2D as an active top cell.

Structural, Electrical and Optical Properties of Molybdenum Oxide Thin Films Prepared by Post-annealing of Mo Thin Films
Molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using DC magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°C) with flow oxygen at 200 sccm (standard Cubic centimeter per minute). The crystallographic structure of the films was obtained by means of x-ray diffraction (XRD) analysis. An atomic force micr...

متن کاملTi/Si thin films during ultra rapid thermal annealing
WC introduce a new technique for rapidly heating (10’ “C/s) thin films using an electrical thermal annealing (ETA) pulse technique. By applying a high-current dc electrical pulse to a conductive substrate-heater material (Si), joule heating occurs thus heating the thin film. This method was demonstrated by heating thin films of aluminum at rates ranging from lo3 to lo6 “C/s. The temperature of ...
متن کاملFacile control of long range orientation in mesoporous carbon films with thermal zone annealing velocity.
Ordered mesoporous carbons exhibit appealing properties for many applications, but their function and performance can depend critically on their structure. The in-plane orientation of 2D cylinders from the cooperative assembly of Pluronic P123 and resol has been controlled by application of cold zone annealing (CZA). By varying the moving rate, the preferential in-plane orientation of the self-...
