Abstract
This thesis describes and analyzes various kinds of engineering options for monocrystalline materials for photovoltaics. Monocrystalline semiconductor materials are known for its good electrical performance, but it is not without its drawbacks for its use as solar cells. This thesis explains a little background of solar cells, and describes ways to overcome many of the limitations that conventional solar concentrators fabricated with monocrystalline semiconductor materials have, such as its high cost, mechanical rigidity, heavy weight, opacity, etc. Luminescent solar concentrators (LSC) – a concentrator system that redirects the unused photons through the use of organic dyes – are introduced and new methods for overcoming some limitations of conventional concentrator systems based on lenses and trackers are discussed. Through careful design considerations, an LSC system where more than twice the photons are indirectly collected can be fabricated, and the optics behind the luminescent waveguide is explained.
