FULL DESCRIPTION
ITO GLASS SUBSTRATE (Indium tin oxide) conductive glass belongs to the group of TCO (transparent conducting oxide) conductive glasses. An ITO glass has a property of low sheet resistance and high transmittance. It is mostly used in research and development. ITO coated glasses are widely used to organic/inorganic heterojunction solar cells,Schottky solar cells, CdTe solar cells and other various thin film solar cells as transparent semiconductor oxide electrode materials since their transparency and high conductivity.
ITO – is an Indium Tin Oxide, it is a solution of Tin Oxide – SnO2 and Indium Oxide – In2O3 in the desired ratio of 90% In2O3, 10% SnO2 by weight. This solution results in the transparent and colorless thin layers which vary from yellowish to gray.
The resistance of Electrical heating can expose you to hypothetically lethal voltages. We recommend that you use only low voltage power supplies for this application. Do not use high voltage supplies.

CLEANING AND HANDLING
While cleaning of ITO slides, safety apparel and protection should be wear. The cleaning process should be done in a fume hood to avoid contamination and maintain impurity free environment.
At the time of slides handling, the researcher should use powder free non-latex gloves, which should handle carefully. While experimenting, if researched use substrate with bare hands, then chances of contamination of coated surface due to finger oil is very high. Therefore it advised using nylon or polyester gloves. Each slide is well packed in moisture free paper and placed is a way that, it should not rub each other.
During experimenting organic contaminant and dust particle present in the surrounding may adsorb on the surface of Indium tin oxide coating and hence clean the substrate become mandatory. Following is the cleaning method for ITO products.
Techinstro advised using the following procedure for ITO layer cleaning.
• Sonication of the sample plays an important role in the cleaning process of the substrate.
• Initially, take acetone and mixed with the substrate, which is to be cleaned and sonicate approximately for 20 minutes.
• Then take out of sample out of sonicator and make it dry.
• Take Isopropyl alcohol (IAP) along with ITO plate for re-sonication for 20 minutes.
• Now take out the sample and placed in UV-ozone instrument to remove the remaining organic contaminant. It also increases the hydroxyl concentration due to oxidation at surfaces.
• Then placed the substrate in a vacuum oven to remove organic solvent used during the cleaning process.
• After proper cleaning placed a sample in the desiccator until its uses.
Lead Attachment (Electrode Formation)/ Electrical Connections
To use the ITO coated glass plate as an electrode, it is necessary to attached leads to the conductive part of the ITO plate. There are various methods available to make better electrical contact with conductive film and probes. The thickness of Indium tin oxide layer is mere hence it is necessary to attached probe at proper coating layer point. Alligator clips make contact between two in a way that the clips cut through the layer or embed in it. It develops resistance between contacts and reduces current which is carried by conductive coatings. It also shows the drop in voltage.
In another method, the probes attach with the help of highly conductive silver paste or bus compositions. In this case, the silver bus is applied on the ITO surfaces (i.e. on edges) and dried over there. The surface becomes highly conductive with the ITO transparent layer. Then attach the alligator pins in a way that it should penetrate silver bus and transparent conductor and make excellent contact in between. In this case, the silver bus material and ITO plate are both conductive; hence there is no high voltage and current drop.
An alternative method of electrode formation, the copper conductive tape is used for the connection of probe, and Indium Tin oxide coated plate. The conductive copper tape which is having lower thickness placed on a substrate and probe in a manner that it gets firmly attached to each other. This tape made the development of little resistance and current passed without a drop. The observed voltage drop is small.
In one of the methods of attaching probe with conductive coatings with the help of silver bus composition or silver paste, but in this case, a fine wire of highly conductive metal such as copper, platinum, gold, silver, etc. has used. This method is known to be the highly used method throughout.
Electrical Characteristics Measurements
While selecting ITO coated glass plate, the resistivity is vital. The demand of resistivity varied according to the application of end users. There are numbers of methods available to determined resistance.
As per the basic properties of electricity, resistance is a ratio of the voltage applied between two electrodes attached to the surface of a thin conductive layer of the sample and current passes between them. In a case of ITO sample, the resistance is known as surface resistance “Rs.”
The resistivity of ITO glass sample measured by multimeter or 4 probe tester.
By using a multimeter, there are following two ways to determine surface resistance.
1). The distance between two probes of multimeter should be 1 cm and placed the probe at an angle of 45 degrees to the surface so that you can get the specific resistivity of the substrate.
2). Cut ITO thin film in a square shape and coat the copper foil on upward and downside of the ITO film. Then place two probes on the copper foil and get reading for the sheet resistance.
The ITO coating is not uniform and isotropic due to its morphological variability. At the time of experiment, error or misplacing of electrodes orientation on the surface of ITO substrates also responsible for the resistance deviation. When alligator pins are attached to the substrate, there are chances of damaging thin film coating are higher. Hence it is advisable to touch surface lightly with the probe. This experiment also includes fringing effect, which is having some contact resistance.
