摘要： An imaging device may include single-photon avalanche diodes (SPADs). To improve the sensitivity and signal-to-noise ratio of the SPADs, light scattering structures may be formed in the semiconductor substrate to increase the path length of incident light through the semiconductor substrate. To mitigate crosstalk, an isolation structure may be formed in a ring around the SPAD. The isolation structure may be a hybrid isolation structure with both a metal filler that absorbs light and a low-index filler that reflects light. The isolation structure may be formed as a single trench or may include a backside deep trench isolation portion and a front side deep trench isolation portion. The isolation structure may also include a color filtering material.

摘要： A system for providing a solar harvesting building envelope is disclosed. The system includes a plurality of solar harvesting apparatus configured to be installed as or on a building envelope in manner like that of traditional shingles or siding. The apparatus includes a frame having a photovoltaic end wall, as well as reflective base and side walls. A translucent, wedge-shaped body layer is positioned on the frame. A luminescent species film is positioned at and substantially parallel to a base of the wedge-shaped body layer, such that the luminescent species film is positioned at an angle relative to the photovoltaic end wall. Light incident on the wedge-shaped body layer is concentrated towards the photovoltaic end wall, such as through absorption and re-emission along with scattering by the luminescent species film and internal reflection by the wedge-shaped body layer and the reflective base and side walls of the frame. A plurality of apparatus may be wired together to create the building envelope, which has the added advantage of substantially eliminating shading losses of traditional solar harvesting systems.
