The sensitivity of energy requirements to process parameters for CuInSe/sub 2/ module production

摘要

The energy input requirements for thin-film PV (photovoltaic) modules are discussed, using CuInSe/sub 2/-based cells as an example. Energy payback times and energy ratios are calculated over a range of insolation levels for various semiconductor deposition techniques. The sensitivity of the energy requirements to single and double process parameter variations for the stacked elemental layer technique is also investigated.
