https://en.wikipedia.org/wiki/Optical_rectennaEconomics of optical antennas
Optical antennas (by itself, omitting the crucial diode and other components) are cheaper than photovoltaics (if efficiency is ignored). While materials and processing of photovoltaics are expensive (currently the cost for complete photovoltaic modules is in the order of 430 USD / m2 in 2011 and declining.[13]), Steven Novack estimates the current cost of the antenna material itself as around 5 - 11 USD / m2 in 2008.[14] With proper processing techniques and different material selection, he estimates that the overall cost of processing, once properly scaled up, will not cost much more. His prototype was a 30 x 61 cm of plastic, [glow=red,2,300]which contained only 0.60 USD of gold in 2008, with the possibility of downgrading to a material such as aluminum, copper, or silver.[/glow][15] The prototype used a silicon substrate due to familiar processing techniques, but any substrate could theoretically be used as long as the ground plane material adheres properly.
