Can glass improve solar energy transmission?

Next we discuss anti-reflective surface treatments of glass for further enhancement of solar energy transmission, primarily for crystalline silicon photovoltaics. We then turn to glass and coated glass applications for thin-film photovoltaics, specifically transparent conductive coatings and the advantages of highly resistive transparent layers.

How much light does float glass transmit?

Current commercial float glasses transmit ~90% of incident light, with the primary sources of loss being absorption and reflection. If the glass is AR-coated, it is possible to achieve ~98% light transmission. Here, we focus on the bulk glass material itself, and coatings or nanopatterning are beyond the scope.

How does transmission affect power output in a PV cell?

As discussed in Sect. 48.1, in PV cells, the increase in transmission leads to an increase in short-circuit current \ ( (J_ {\text {sc}})\), which, neglecting for example the effect of series and shunt resistances in the cell and the behavior of the balance of system components, leads to a proportional increase in power output.

Why are photovoltaic cells laminated?

In practice, due to the susceptibility of typical photovoltaic cells to moisture and the requirement for these systems to survive an outdoor environment for \ (\mathrm {25}\) years, the cell is laminated to a piece of high-transmissivity soda-lime-silica glass.

Can SLS glass be used in PV modules?

SLS glass is ubiquitous for architectural and mobility applications; however, in terms of its application in PV modules, there remains room for improvement. In the current paper, we have reviewed the state of the art and conclude that improvements to PV modules can be made by optimizing the cover glass composition.

Can iron be removed from glass to increase transmission?

However, removal of iron from the glass to increase transmission creates a problem in terms of increased UV transmission, which more rapidly ages the polymeric C-EVA or T-EVA leading to reduced PV module service lifetimes.
