Photovoltaic energy systems - recycling or utilization?
PublicationW ostatnich latach obserwuje się znaczny wzrost produkowanej ilości modułów fotowoltaicznych (do 40% rocznie), przy czym 90% światowej produkcji ogniw do zastosowań naziemnych stanowią ogniwa z krystalicznego krzemu. Wskutek tak znacznego wzrostu produkcji pojawił się problem zaopatrzenia producentów w odpowiednią ilość krzemu odpowiedniej jakości. Dodatkowo za parę lat trzeba będzie dokonać wymiany modułów, pracujących od lat...
