Develop In- free TCO films with carrier concentration in the range 3x1019-3x1020 cm-3 with an electronic mobility greater than 20 cm2 (Vs)-1 to enable its dual use as a front and back electrode in SHJ solar cells. This will allow for a relative cost reduction of 5% and relative efficiency gain of 2%.
Establish processes for realizing conformal TCO coatings with sheet resistivity below 5x10-4Ωcm, transparency above 88%, contact resistance below 2x10-5Ωcm for large area planar LEDs and LEDs incorporating high aspect ratio (H/W greater than 2) nanostructures, without detriment to the Cost of Ownership.
Develop In-free TCO material with sheet resistance below 10 Ω/□ and visible absorption below 5%. Developed film roughness should lead to leakage current below 10-3 mA/cm2 without detriment to the Cost of Ownership.
To establish processes and up-scaled equipment, to a minimum 30x30 cm2 process area, that simultaneously reduces cost and increase technical effectiveness of TCOs deposited by low damage techniques.
To perform life cycle assessments of the environmental impact of the developed TCO materials and cost of ownership analyses of their formation technologies over the entire period from application in manufacturing, through component operation into waste management.
