Spring 2015Grew a mix batch of 25 samples with following deposition parameters:(1) 0.75 mA/cm2, 0.875 mA/cm2, 1 mA/cm2(2) -0.62 V(3) -0.685 VComposition of solution: 0.1M S + 0.1M Na2S2O3.5H2OStir rate: 250 rpmDeposition Temperature: 150 oC Substrate: Mo, FTO

Annealing TreatmentIn2S3 films crystallinity will be studied as a function of annealing treatment by.Annealing treatment includes the following:

(1) Intense pulse light (IPL) treatment (3 different intensities)(2) Oven-based annealing in the presence of inert gas (150, 200, and 250 oC for 2 hr)Labelled 15 Samples have already been given to Dr. Seok on February 5th, 2015.

Papers in preparation/publication processPaper submitted to IEEE Journal of Photovoltaics was not accepted (December 9th, 2015).Same paper after slight modification was submitted to Journal of Electrochemical Society (January 30th, 2015).“Morphological and Compositional Analysis of Electrodeposited Indium Sulfide (In2S3) Films”Paper in preparation for publication in Solar Energy Materials and Solar Cells. “A Review on Record Efficiencies for Indium (III) Sulfide (In2S3)-based Thin Film Solar Cells (TFSC) and Recent Developments “

Future Work/GoalsCharacterization (mainly XRD) of annealed samples. Study and analyze the data.Prepare a paper based on experimental results and observations.Use of mapping feature to study the elemental distribution.Thickness measurements.
