Selecting glass for a project is an important and sometimes dificult task, to assist in this process G.James ofers the following recommendation for viewing glass samples.
The advancements in glass technology, such as rare-earth doping and the incorporation of heavy metal oxides, have shown promise in optimizing the solar spectrum for improved energy absorption and conversion.
Solar Energy Absorptance (Ae, %) is the percentage of the sun's energy that is absorbed by glass. Solar Factor or Total Solar Energy Transmittance or g-value (g%) is the total solar radiation transmitted by the glass. Shading Coefficient (sc) is Solar Factor divided by 0.87.
In the numerical solutions of the distribution of absorbed solar radiation in various glazing systems presented here, each thick element in a glazing layer was divided into a fixed number of 'slices', and the radiation absorbed at coated interfaces was added to the amount of radiation absorbed in the adjacent 'slice'.
Advances in glass compositions, including rare-earth doping and low-melting-point oxides, further optimize photon absorption and conversion processes. In addition, luminescent solar concentrators, down-shifting, downconversion, and upconversion mechanisms tailor the solar spectrum for improved compatibility with silicon-based solar cells.
