Photovoltaic panel performance is improved by means of an optical surface technology that is applied to the front surface
of a panel. The technology is comprised of an array of micro lens structures embossed into highly transmissive polymer
film or glass. The film version may be applied to new or previously installed photovoltaic panels; the glass version is
appropriate for new panels.
The structures are designed using a proprietary ray tracing program to concurrently optimize path length (the length of
the path of light through the photovoltaic material), total internal reflection and anti-reflection. The structures may be
optimized for diffuse light conditions, incoming ray angles and/or time of day. Additionally, the rays may have their
paths modified or be redirected by the structures to improve performance at specific band gaps that are customized for
particular photovoltaic materials.
