5 times the output ? 230 watts of energy on just one centimetre? That can't be possible since that would work out to more than 1KW/M2 
"230 watts of energy on just one centimer
of solar cell"
"this means there'd be a decrease in the needed quantity of photovoltaics, thereby lessening installation costs."
doesnt change the amount of area they are gathering light from, just reduces the amount of costly solar cell required to convert that light to electricity.
