Composed of light-absorbing, colloidal quantum dots linked to carbon-based fullerene nanoparticles, these tiny two-particle systems can convert light to electricity in a precisely controlled way.
The kinds of analysis that report massive, sustained, falling costs for renewable plants often assume that capital costs are recovered in steady-state fashion over the full, rated, life-cycle of the machinery, when in fact investors inthesesystems always strive to recover their costs much sooner to beat the diminishing returns that set in once two-thirds of the life-cycle is spent.
