It is possible to introduce special elements with highly reflective surfaces, like aluminum cladding or other reflectors of high reflectivity, which increase reflected radiation quite a lot. However, such reflectors are used for solar collectors of active thermal systems, rather not for building passive solutions (not to cause the glare effect).

A solar mirror contains a substrate with a reflective layer for reflecting the solar energy, and in most cases an interference layer. This may be a planar mirror or parabolic arrays of solar mirrors used to achieve a substantially concentrated reflection factor for solar energy systems. See article "Heliostat" for more information on solar mirrors used for terrestrial …

A typical solar light pipe system consists of a solar collector on the roof that collects the sunlight by focusing it into a pipe with highly reflective internal surfaces. When sunlight hits on the collector, it is focused into a beam and enters the piping system through an optical device that is used to direct the light into one end of the pipe.
Reflectors to Improve the Performance of Solar Collectors
A key advantage of reflectors over just adding more collector area is that reflectors add to solar gain without adding to collector heat losses. A typical collector operating with a modest sun level of 500 watt/sm under winter conditions might have an efficiency around 30%, but if you can boost the sun intensity to 1000 watts/sm with a reflector, the …
