SPRAY PYROLYSIS BASICS
Q. Does anyone have experience in depositing CuInS2 films by spray pyrolysis? Any helpful suggestions would be appreciated.
Alan Chapman- SWINDON, UK
A. I suggest two methods to find this info: 1) a patent search for solar cells, or 2) U.S. Department of Energy (www.DOE.gov) web site in which look for NREL (National Renewable Energy Lab). NREL has done a lot of work in this material.

Q. MY DEAR SIRS.
I'M WORKING IN PV AND SEMICONDUCTOR SURFACES. FOR THE LONGEST TIME I HAVE NO SUPPORT OR EQUIPMENT FOR DEPOSITING CVD OR SPUTTERING. BASICALLY I AM A TECHNICIAN. BUT I HAVE A LOT OF INTEREST TO DO WORK WITH PV CELLS. ALSO I REQUEST YOU TELL ME WHAT SUPPORT CAN MAKE LEARNING ABOUT SOLAR CELLS BY SPRAY PYROLYSIS OR ANY ORGANIC PV. I WILL BE VERY THANKFUL IF you RESPOND.

Q. Before spraying the solution, How are the pressurized air and the solution mixed (or) what is the principle of mixing pressurized air and the solution together?

A. My Dear;
My name is Ahmed Naji. and I am an assistance teacher in faculty of science, department of physics. Also I finished five years of study in deposition films by spray pyrolysis. So I hope you can specify your problem in CIS deposition to enable me to help you.
I am working now in solar cell fabrication company as an expert in spray pyrolysis technique to deposit TCO layer with spray pyrolysis.
I am interested also for CIS application as an absorber layer in solar cell instead of CdTe.
So I think we can enrich our information by sharing.

Hi cousin Ahmed. Thanks for wanting to enrich by sharing, but there are open questions on the table. Can we try to answer them or explain to the inquirers what needs to be specified to start that process? Thanks.

A. There is a lot of papers about this topic,
I have worked on this subject for several years on my research for M.C.S Degree.

Hi, Omar. Could you then favor us with the name and URL of one of those papers?
People say they want to share, and that's what the forum is here for, but then they don't take the steps to do it :-)
What am I missing? Thanks!

How to make a homemade spray pyrolysis machine
Q. Hi, I'm trying to build a spray pyrolysis equipment, does anybody know where can I find the basics or some guide that can help me? Thanks I'll appreciate your comments...

RFQ: We will do some work in spray pyrolysis research. But we run short of the experimental equipment of spray pyrolysis. We need a spray pyrolysis apparatus to prepare the powder used in lithium cell.

Q. DEAR FELLOW INVENTORS, SCIENTISTS, READERS, RESEARCHERS, ENGINEERS,
I'm A FILIPINO AMATEUR INVENTOR, I'M A FINE ARTS GRAD. BUT I AM INTERESTED IN SCIENCE, ELECTRONIC PROJECTS, POWER AND ENERGY ESPECIALLY POWER INVERTER, FUEL CELLS, SOLAR CELLS, AND POWER CYCLE BATTERY THAT NEVER DISCHARGES WHILE IN USE AS INVERTER BECAUSE THE DISCHARGE OF BATTERY IS MY MAIN PROBLEM EVER SINCE I STARTED TO MAKE A PROTOTYPE OF MY INVERTER.
SO I RESEARCH THESE THINGS FOR ALMOST 6 YEARS UNTIL NOW. IN TRYING TO SOLVE IT THRU SOLAR CELLS, FUEL CELLS, SINCE THESE THINGS NEVER DISCHARGE WHILE IN USE OR IN OPERATION. USUALLY IT TOOK 3 HOURS TO CONSUME THIS BATTERY, BE IT NICAD OR LEAD ACID TYPE. MY INVERTER IS POWERED BY 12V NICAD OR ANY TYPE AS LONG AS IT RANGED FROM 3 AMPERES UP. IT'S ONLY 150 WATTS POWER BUT I'm PLANNING TO BUILD HIGHER VERSION SOMEDAY.
SO CAN YOU TEACH ME HOW TO MAKE SPRAY PYROLYSIS MACHINE FOR SOLAR CELL PRODUCTION? CONDUCTIVE GLASS IS NOT AVAILABLE IN THE PHILIPPINES. SOLAR CELL AS WELL, SAME WITH PLATINUM METAL AS CATALYST FOR FUEL CELL...HARD TO OBTAIN. JUST FOCUS ON HOMEMADE BATTERY CYCLE CHARGER W/C IS PORTABLE AND HIGH POWER THAT NEVER DISCHARGES...ANYONE COULD HELP ME SOLVE THIS PROBLEM? THANKS.
