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 Source: Stern Review “The Economics of Climate Change”; IEA

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 CO2 concentration in atmosphere (in ppm) CO2 emissions from fossil fuels (in M t/year) CO2 concentration in atmosphere Carbon emissions from fossil fuels Pre-industrial CO2 level Source: CO2 concentration: C.D. Keeling, T.P. Whorf et. Al., “Air samples collected at Mauna Loa Observatory Hawaii”; CO2 emissions: G. Marland, B. Andres, T. Boden, “Global emissions from fossil burning”

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 Source: Industry Reports; Litsearch
