Abstract
This article studies the throughput of non orthogonal multiple access (NOMA) using reconfigurable intelligent surfaces (RIS) when the source harvests power from the sun using a photovoltaic system. The harvested energy from the sun is made continuously. The harvested energy during
α
T
seconds is employed to broadcast data to NOMA users over
(
1
-
α
)
T
seconds where
0
<
α
<
1
and
T
is frame duration. The value of
α
is wisely chosen to maximize the throughput.
