Abstract: A solar energy harvesting and storage system is disclosed having a dual-sided lithographically integrated light-to-electrical energy converter. The integrated light-to-electrical energy converter has at least one array of photovoltaic, cells having an array of optoelectronic components, each of which have a compound optical structure that spatially separates light into multiple wavelengths and a P/N junction having a gradient of semiconductor materials and/or dopants responsive to a narrow band of wavelengths. A common electrode connects the optoelectronic components and the common electrode is electrically connected to at least one integrated DC to AC inverter. Also disclosed is a dual-axis solar tracking system upon which the dual-sided lithographically integrated light-to-electrical energy converter is mounted. The dual-axis solar tracking system has two stages of tracking mounts, each tracking mount has a plurality of leaf-springs in a vertical arrangement.

Also disclosed is a dual-axis solar tracking system upon which the dual-sided lithographically integrated light-to-electrical energy converter is mounted. The dual-axis solar tracking system has two stages of tracking mounts, each tracking mount has a plurality of leaf-springs in a vertical arrangement. The leaf springs have differential coefficients of expansion and contraction so that each tracking mount tracks a solar light source in an orthogonal direction from the other tracking mount.
