The paper is somewhat dated, the payback time is less with current technology. Lowest energy input would likely be a thin-film manufacturing process such as employed by First Solar.

The reason is: 1. There are a LOT of manufacturers all working at different efficiency levels. 2. Improvements are made almost daily. 3. The glass panels are not the only ones being produced anymore. There are now some rubber like panels as well as a paint on material. If you need an answer for a project, there are tons of sites on the web that can tell you how to make a photovoltaic cell at home pretty easily. You could build one and get the results yourself.<br><b>References : </b><br> I do not believe you can get an answer to this. The reason is:
