Sanjib.A: What is the lifetime of commercial PV cells
They all say 25 years, but most the best warranty available--SunPower--states in the fine print that its guarantee is that you will only loose --.4% a year in output current, except the first year where you loose 8% and my the end of the warranty you loose 35% by year 25. Most of the others don't give such detailed specs and only warantee for 10 years.

Okay. What is the life of the commercially available PV cells at present? 10-15 years?

Sanjib.A: The lifetime of the materiall is one of the hurdles that need to be cleared before commercialization. The researcher's plan is to match its lifetime to that of the underlying solar cell before commercialization.

"...But Sfeir claims their material is almost as good, and more importantly, easier to apply onto existing solar cells."
It might be early to ask this question: What would be the life of this material once applied or how requently this coating needs to be applied to gain efficiency out of the existing solar cells?

Using this revolutionary print or paint-on polymer not only doubles the number of electrons prouced but increases the efficiency of any solar cell. Right now its boasting 44% efficiency that rivals the efficiency of expensive multi-junction cells made from III-V materials like gallium arsenide (GaAs) and they havn't even started optimizing yet. Solar is looking very bright for the future.
