Abstract

Some photovoltaic cells have a front face accepting incoming incident light and opaque gridlines overlying part of the front face, electrically bonded to the face, with upper reflective facets oblique to the plane of the front face and producing outgoing reflected light. An optical interface parallel to and in front of the front face transmits incoming light to the front face and to the gridlines and reflects back towards the front face by total internal reflection at least some of the outgoing reflected light. Some photovoltaic devices have a triple junction photovoltaic cell, a single junction photovoltaic cell, and a reflective surface arranged to distribute incoming light between the cells. The surface may be a frequency-selective mirror that apportions light so when the cells are in series the power produced, and preferably the photocurrent, is greater than if all the light fell on the triple junction cell alone.
