Scientists develop mega-thin solar cells that could be shockingly easy to produce: ‘As rapid as printing a newspaper’

Jump

  • Im talking about limitations of thin solar cells largely. I think there is usually enough doped material in regular cells that it usually isnt looked at.

  • Why not? I have not looked at this in forever so im probably wrong but I thought that these pn pairs end up creating some band gap. Over time that band gap widens until the energy from the sunlight just isnt strong enough to move through the system. In the end, it has a finite qty of holes so that limit depends on the qty of doped materials.

    Again i dont remember well so 🤷

  • Yes, correct me if I am wrong buy is that not the case?

  • My movie was princess and the goblin. I watched it on a 10x10 in monitor that had the VHS in while I worked at my family's business where I did labor at 10 years of age 30+ hours a week. Good times

  • I would imagine it could only be useful for 30 minutes before the cell would be unusable. Arent solar cells just P-N junctions where if it is really thin it would just run out of holes to fill?

    Edit: why am I being downvoted? To my limited understanding from my electrochemistry courses from 10 years ago, photovoltaics depend on the density. Theres only a limited amount of free electrons and only a limited number of free holes. The thinner the material the less likely an electron hole can get filled with whatever N-doped semiconductor used.

  • They chant that because it means something different depending on who says it. The Palestinians have been chanting this slogan for many years since the PLO times. The call was to unite the people to show unity between the people of gaza to west bank. However, when Hamas took power, the chant turned into something antisemitic. So you will hear both sides now, unite the people and wishes for terror.
