Some companies are experimenting with glass that only allows certain light colours through therefore lowering the temperature.
One way mirror solar panel.
Using broken mirrors with solar panels to boost the power output of a regular pv photo voltaic diy solar panels.
As the name suggests this film gives the window a mirror like highly reflective look on either the outside or the inside of the window depending on the lighting conditions.
Heat has a negative effect on solar cells.
Mirrors don t strictly increase the efficiency of a pv panel.
The extra not usable light increases temperature also.

Prevent nosy unwanted onlookers from peeping through your window during the day with buydecorativefilm s one way mirror silver 5 window film.
Two way mirrors also referred to as one way mirrors are types of glass typically used for security and privacy purposes for businesses.
Lets take hollow glass sphere probably large and use a one way mirror all the way around the inside of the sphere with solar panels mounted onto multiple sides of the interior of the sphere.
Its fraction of incident solar energy converted to electricity remains the same.
But adding mirrors or lenses to a pv system increases the area over which sunlight is collected so yo.
This complex mirrored glass is unique and only available through a select number of glass companies.
I did an experiment and checked the voltage with and without mirrors at up to 12 load resistance settings using a decade box and found that one mirror of about 3x the width of the solar cell at an angle to match the mirror s reflection to the solar cell area about 20 degrees only gave about 25 increase at the max.
Power point for each.
Using glass mirror panels this photovoltaic solar panel power is increased by 30.
This enables the use of cells with a high cost per unit area such as gallium arsenide in a cost effective way.
A one way mirror or one way glass or two way glass is a mirror that is partially reflective and partially transparent.
This one way mirror bubble would kill the output of the solar cell.
Some special solar pv modules include concentrators in which light is focused by lenses or mirrors onto smaller cells.
There are eight heliostats on a pod with the mirrors motors operated by small two watt photovoltaic solar panels.
