In a conventional photovoltaic module, some light that falls between the solar cells is internally reflected onto the cells via the backsheet and the glass-air interface of the module; thus, a module can be considered a static concentrator. We present a simple ray tracer that computes a module's optical concentration as a function of cell separation, cell geometry, and the optical properties of the encapsulants. The ray tracer's primary simplification is to divide the module's backsheet into...[Show more]
