The viability of a concentrator technology is determined by five interrelated factors: economic benefit, cell performance
under concentration, thermal management, optical performance and manufacturability. Considering these factors, the 5-
10x concentration range is ideal for silicon-based receivers because this level of concentration captures the bulk of
available economic gains while mitigating technical risk. Significant gains in capital efficiency are forsaken below the
5x concentration level. Above the 10x level of concentration, marginal improvements to economic benefit are achieved,
but threats to reliability emerge and tend to erode the available economic benefit. Furthermore, optic solutions that
provide for concentration above 10x tend to force a departure from low-profile flat-plate designs that are most adoptable.
For silicon based receivers, a 5-10x level of concentration within a traditional module form factor is optimal.
