Abstract

Spray pyrolysis has been widely used for the prepn. of thin (.apprx.0.1 mm) and transparent SnO2 films on glass substrates. The parameters of the spray pyrolysis for the prepn. of thick SnO2-Sb2O5 conductive films on Ti substrates were studied for electrochem. use. The resistivity of the films exhibits a min. for a Sb concn. of .apprx.3 at.% (precursor soln. concn.) and for a prepn. temp. of 550 Deg. As far as the compn. is concerned, the Sb concn. in the oxide films is about twice as large as that in the corresponding precursor soln. The dependence of the oxide loading on the substrate temp. and nature and the influence of the spray conditions also are discussed. [on SciFinder (R)]

Gallium

Gallium is a chemical element with the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminium, indium, and thallium). Elemental gallium is a relatively soft, silvery metal at standard temperature and pressure. In its liquid state, it becomes silvery white. If enough force is applied, solid gallium may fracture conchoidally.

Pyrolysis

The pyrolysis (or devolatilization) process is the thermal decomposition of materials at elevated temperatures, often in an inert atmosphere. Temperature can be understood as thermal vibration. At high temperatures, excessive vibration causes long chain molecules to break into smaller molecules. The word is coined from the Greek-derived elements pyro "fire", "heat", "fever" and lysis "separating". Pyrolysis is most commonly used in the treatment of organic materials. It is one of the processes involved in charring wood.

Dye-sensitized solar cell

A dye-sensitized solar cell (DSSC, DSC, DYSC or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. The modern version of a dye solar cell, also known as the Grätzel cell, was originally co-invented in 1988 by Brian O'Regan and Michael Grätzel at UC Berkeley and this work was later developed by the aforementioned scientists at the École Polytechnique Fédérale de Lausanne (EPFL) until the publication of the first high efficiency DSSC in 1991.
