An apparatus for generating electricity from solar radiation having a solar spectrum is provided. The apparatus includes a photovoltaic mirror comprising a plurality of photovoltaic cells, the photovoltaic mirror configured to separate the solar spectrum, absorb a first portion of the solar spectrum, and concentrate a second portion of the solar spectrum at a focus. The apparatus also includes an energy collector spaced from the photo-voltaic mirror and positioned at the focus, the energy collector configured for capturing the second portion of the solar spectrum.

Material and antireflection structure designs and methods of manufacturing are provided that produce efficient photovoltaic power conversion from single- and multi-junction devices. Materials of different energy gap are combined in the depletion region of at least one of the semiconductor junctions. Higher energy gap layers are positioned to reduce the diode dark current and enhance the operating voltage by suppressing both carrier injections across the junction and recombination rates within the junction. Step-graded antireflection structures are placed above the active region of the device in order to increase the photocurrent.

Embodiments generally relate to optoelectronic devices and more specifically, to textured layers in optoelectronic devices. In one embodiment, a method for providing a textured layer in an optoelectronic device includes depositing a first layer of a first material and depositing an island layer of a second material on the first layer. Depositing the island layer includes forming one or more islands of the second material to provide at least one textured surface of the island layer, where the textured surface is operative to cause scattering of light.

A solar cell system and a flexible solar panel are disclosed herein. The solar cell system includes a glass housing, a set of rows of solar cells each defining a front side and a rear side and arranged within the glass housing. The solar cell system can also include a reflective element disposed in the glass housing and facing the rear side of the set of rows of solar cells and a first terminal coupled to a first end of the set of rows of solar cells, traversing through and sealed against the first end of the glass housing.
