My own guess is that rather than the completely general «how is quantum mechanics involved with absoprtion / emission», that he wants to know how it is relevant to the Earth's energy balance. (scienceofdoom.com)
With the size decreasing of quantum dots, the distinction of band energy between hole transport layer and optical absoprtion layer will be increased, which can improve the open - circuit voltage of the solar cells. (european-mrs.com)
Hi all, I've been debating this issue for about 6 months, and I won't festoon this post with links, because there aren't any I've found on the web that get to the kernel of the matter - radiative absoprtion - and certainly not broadly enough to satisfy. (illconsidered.blogspot.ru)
