I only know for solid silicium cells since I worked in the field. For thin layers, don´t ask me. So here´s the deal:

- use of a high quantity of energy to produce pure silicium (99,9999%) in the form of a monocristallin bloc (evtl polycristallin)
- use of mechanical energy to removed the impurities on the outside of the bloc (turn the bloc)
- use of mechanical energy to create the "flat"
- use of silicium carbides (neutral to the nature but energy intensive to produce) in the cutting slurry
- enrgy use in the cutting process+oil as a slurry basis
- energy during transportation
- energy and chemicals during the dotation (for the polarities)

- energy used to produce the glass top layer

BUT HERE´s THE WORST:
use of fluor gases to "etch and clean" the cell surface... those gases have a 10000 to 40000 greenhouse effect compared to CO2... luckily, they are now destroyed or recycled.

It slows down global warming as it uses other natural energy instead of natural energy that has been transformed, such as fossil fuels.

sola takes the power from the sun and converts it to electric ( 0 ) emision if we all did this no probs!!!
