3. Intense energy consumption of conventional sources drives CO2 emission
Energy consumption, particularly power generation, is responsible for CO2 emissions
“Energy production is – by far - the most important driver for emissions of greenhouse gases.”
STERN REVIEW: The Economics of Climate Change
“In 2030, global CO2 emissions will be 70% more than today … and power generation will account for almost half the increase.”
International Energy Agency: Emissions report

4. CO2 concentration in atmosphere Carbon emissions from fossil fuels
CO2 emissions and concentration in the atmosphere have been rising substantially in the last ~50 years

9. Two major technologies within Solar PV: the established bulk crystalline silicon cells and thin film as challenger
Solar modules based on crystalline silicon
Solar modules based on thin film depositions
Production:
Solar modules produced on the basis of a (crystalline silicon) wafer
Cell functionality, e.g. contacts for electricity extraction, applied onto crystalline wafer
Economic & ecologic characteristics:
Current silicon shortage makes production significantly more expensive
Relatively high (vs. thin film) CO2 emissions during production due to higher raw material intensity
Production:
Modules produced via deposition of very thin films onto a glass substrate
Cell functionality, e.g. contacts, also deposited via thin transparent films
Economic & ecologic characteristics:
Lower module production costs and CO2 emissions due to better raw material efficiency
Competition of several technologies (e.g., Silicon thin fim, CdTe, CIS/ CIGS) additional driver for cost reductions
Market share decreasing
Market share increasing
