LJ40 captain reported overshooting the cleared altitude when the first officer misinterpreted an ATC...

Narrative:

We departed teb on the teterboro one departure. All went according to procedure. We were cleared to 11;000 ft. Heading 280. We were having an issue with a pilot windshield which had my attention. The co-pilot was handling the radios; and I was pilot flying. Eventually; we were assigned heading 290; so I turned the heading bug. I soon noticed we were now climbing to 19;000 ft in the altitude select; so we continued the climb. I recall at that time; believing that I had not heard a clearance to climb from 11;000 ft to 19;000 ft; but put that off to the fact that I was distracted with the windshield problem. My co-pilot who was much younger than I; was extremely competent; although he had very limited time in this environment. So I recall not questioning the fact that he had received a clearance to 19;000 ft. So I did not question it. That was a mistake on my part. I was the experienced pilot in command. We were immediately questioned by the controller as to who had cleared us beyond 11;000 ft. I did not know and the co-pilot believed it was the controller. I turns out; the co-pilot had misinterpreted the turn to 290 as a climb to 19;000 ft. We were in error; and I had failed to question him on the clearance to 19;000 ft. My distraction; and us not being on the same page; resulted in this crew error.
