Talk:Sun-free photovoltaics

Copyright concerns
I have tagged this article for copyright investigation: I found 2 separate instances from each of the first 3 cited sources where the source text had been directly copied into this article. I suspect that more of the same is here and most of this article is a rearrangement of non-free text. As such, rather than my removing the copyvios piece by piece until almost nothing is left, the article should be rewritten from scratch. Franamax (talk) 21:37, 11 August 2011 (UTC)

Question of page relevance?
Hi, I'm just wondering whether this page is really necessary? So called "Sun-free photovoltaics" are not a different technology to Thermophotovoltaic devices. The sources used in this article indicate this also. Would it not be better to include this information in the page for thermophotovoltaics in some way and then delete this page? Kind regards, --EL7444 (talk) 15:17, 23 August 2019 (UTC)
