1.Question 1

What is the difference between printing and coating?

Printing and coating is the same thing

Printing can produce patterns, such as text, while coating cannot

Coating can produce patterns, such as text, while printing cannot

Correct

That is correct

Printing allows for patterning, while coating only allows for very limited patterning.

2.Question 2

Select the correct statement(s)

Polymer solar cells can be roll to roll processed because the layers can be processed from solution

Correct

That is correct

One of the key advantages of polymer solar cells is that they can be produced in roll to roll process. This is made possible by the fact that all layers can be processed from solution.

Polymer solar cells are always made using ITO as a transparent conductive oxide

5.Question 5

List the main advantages of polymer solar cells as compared to first and second generation devices

abcd

Correct

Specific advantages of organic solar cells include rapid, ultra-low-cost manufacturing, a thin, lightweight, and flexible form factor. The technology inherently allows non-toxic and can be environmentally friendly.
