Halide Perovskite

In recent time, organic–inorganic halide perovskite solar cells govern photovoltaic field, due to its remarkable development on the power conversion process. Still, large variations in device efficiency and basic physical properties are reported. This is due to variations during film fabrications and consecutive treatments employed. Here, we report a layer by layer deposition of inorganic perovskite (CsBi3I10) and lead halide perovskite (CH3NH3PbI3) thin films. We find that the absorbance for corresponding thin film goes on increasing dramatically. UV-vis spectrum of film recorded to find the band gap of films, ˜1.55 eV optical band gap have been obtained for the film fabricated layer by layer. We further study the fabrication of different perovskite layers impact on microstructure, surface morphology and optical properties. The optical and structural characterization outcomes all suggests the perovskite films processed by using the layer by layer fabrication are well controlled, making this processes an auspicious technique to fabricate thin-films for numerous prospective device applications and scientific studies.

Two Parameters

Morphology modulation offers significant control over organic electronic device performance. However, morphology quantification has been rarely carried out via image analysis. In this work, we designed a MATLAB program to evaluate two key parameters describing morphology of small molecule semiconductor thin films: fractal dimension and film coverage. We then employ this program in a case study of meniscus-guided coating of 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C<sub>8</sub>-BTBT) under various conditions to analyze a diverse and complex morphology set. The evolution of morphology in terms of fractal dimension and film coverage was studied as a function of coating speed. We discovered that combined fractal dimension and film coverage can quantitatively capture the key characteristics of C<sub>8</sub>-BTBT thin film morphology; change of these two parameters further inform morphology transition. Furthermore, fractal dimension could potentially shed light on thin film growth mechanisms.
