An energy storage capsule for storing energy in the form of photons. The body of the capsule may surround a sealed vacuum environment in which several layers of reactive material are contained, including an inner reflective coating, a first photovoltaic cell, an optical amplification medium, a second photovoltaic cell, and an outer reflective coating, provided in that order. The body of the capsule may also be reflective, for example polished aluminum. Light may be emitted from an LED wafer which may be integrated with the surface of the optical amplification medium, directed at the several layers of reactive material. Some photons may be reflected by the reflective material, storing them within the capsule, while others may be absorbed by the photovoltaic cells, powering the LEDs to transmit more photons. The thermal environment of the energy storage capsule may be maintained such that the LEDs can operate at over 100% efficiency.

According to some embodiments, the present invention provides a novel photovoltaic solar cell system from photovoltaic modules that are vertically arrayed in a stack format using thin film semiconductors selected from among organic and inorganic thin film semiconductors. The stack cells may be cells that are produced in a planar manner, then vertically oriented in an angular form, also termed herein tilted, to maximize the light capturing aspects. The use of a stack configuration system as described herein allows for the use of a variety of electrode materials, such as transparent materials or semitransparent metals. Light concentration can be achieved by using fresnel lens, parabolic mirrors or derivatives of such structures. The light capturing can be controlled by being reflected back and forth in the photovoltaic system until significant quantities of the resonant light is absorbed. Light that passes to the very end and can be reflected back through the device by beveling or capping the end of the device with a different refractive index material, or alternatively using a reflective surface. The contacting between stacked cells can be done in series or parallel. According to some embodiments, the present invention uses a concentrator architecture where the light is channeled into the cells that contain thermal fluid channels (using a transparent fluid such as water) to absorb and hence reduce the thermal energy generation.
