Title: Edge reflector or refractor for bifacial solar module

Abstract

One embodiment relates to a bifacial photovoltaic module having an edge reflector. The module includes a plurality of solar cells in an array, each solar cell having a front side and a back side. A reflector is configured on an edge of the array of solar cells, the first reflector being configured to reflect light onto the front side of a row of solar cells adjacent to the edge. Another embodiment relates to a method of reducing non-uniformity of power generation from a bifacial photovoltaic module. Electrical current produced from solar cells along at least one edge of the array is increased by using a reflective strip facing towards the front side of the solar cells along the edge. Another embodiment relates to a bifacial photovoltaic module having an edge refractor. Other embodiments and features are also disclosed.
