Deposition of Al/Ti electrode layer on PET substrate using ebeam and optimization of electrical properties

The current energy crisis in many countries has led to the search of an efficient renewable energy source. Among those the solar energy is the most abundant and easily available. However harvesting the solar energy requires a much efficient device. Lot of research has been done in this regard and so far the efficiency of traditional solar cell stands around ~50% and for PET films it is much lesser. The potential application of PET films in the solar cells can be very promising provided the fact that the PET film is lighter and logistically more viable. There is a lot of work that is being done to increase the efficiency of PET based solar cells. The base electrode plays a vital role in increasing the efficiency of the cell.
