At the same time, it can also provide thermal insulation.

As a solar photovoltaic (PV) panel, PV-TV can generate electricity at an above-average level of efficiency. But weirdest of all, it can also function as an internal and external "television" (TV) screen—i.e., a giant billboard. (Get it—PV-TV?)

PV-TV has yet to gain popularity outside of Japan, mainly due to its high price, but the technology does seem to have the capacity to make the world that much more Treehugger. $45/square foot ::Metropolis
