Solar Cells: Energy Payback Times and Environmental Issues

Energy payback time (EPBT) is a basic metric of this performance: the lower the EPBT, that is the time it takes for a PV system to generate energy equal to the amount used in its production, the lower will be the emissions to the environment because emissions mainly occur from using fossil fuel-based energy in producing materials, solar cells, modules, and systems.
