There's no question in my mind at to "what is what", guy.

That's good makes two then here that read the bag and new what we was getting

Focussing on the exact quote from your source: "In application, there are two types of photodiodes: 1) photovoltaics and 2) photoconductors. "
"In application" - meaning that there are two modes - photovoltaic and photoconductive, a photovoltaic application and a photoconductive application.
Which application to choose depends on the end desired.

OK --
from reading at the source of that PDF, "OSI", there are specialty, specifically photovoltaic mode photodiodes.
Users are admonished to not reverse bias them (or not by as much as they would anticipate with others.)
http://osioptoelectronics.com/standard-products/silicon-photodiodes/general-purpose-photodiodes/photovoltaic-devices.aspx
for calibrated photodiodes and so on as used in instruments.


Photoconductive types, too

tweaked for speed (speculating that they don't do well in PV mode.)
