The median bid for a wind project was $18.10/MWh; the median for wind+storage was $21, just three dollars higher. The median bid for a solar PV project was $29.50/MWh; the median bid for solar+storage was $36, just seven dollars higher. (Keep in mind what median means: Half the projects bid cheaper than this.)
When quantum dots absorb blue and ultraviolet portions of the solar spectrum, the dot then re-emits a photon at a longer wavelength. That is guided to the glass edges of the window where integrated solar cells collect the light and convert it to electricity.
