Can't help you with "a weird paper on the unexpected efficiency of photosynthesis", try asking a biologist at your local university, or possibly an organic chemist.
Yeah, I looked at Google Scholar to try and find cross-references to anything to do with photosynthesis and came up empty-handed. Annoying because I've been telling people about these guys for years, but can't find the original paper that introduced me to them!
