Energy storage issues of cadmium telluride power generation glass

Are cadmium telluride-based cells better than SI?

Cadmium telluride (CdTe)-based cells have emerged as the leading commercialized thin film photovoltaic technology and has intrinsically better temperature coefficients, energy yield, and degradation rates than Si technologies.

What is cadmium telluride (CdTe)?

Cadmium telluride (CdTe) thin-film PV modules are the primary thin film product on the global market, with more than 30 GW peak (GWp) generating capacity representing many millions of modules installed worldwide, primarily in utility-scale power plants in the US.

What is the bandgap of cadmium telluride & CdSe multijunction solar cells?

Solar cells based on cadmium telluride (CdTe) and cadmium selenide (CdSe) multijunction show great promise for high efficiency cells. The bandgap of CdTe multijunctions for solar cell applicatons is 1.44 eV, a value which is close to the optimal bandgap for single junction solar cell.

Are CdTe solar modules dangerous?

Image courtesy of First Solar. Another strand of concern regarding CdTe solar modules are the chance of carcinogenic emissions if modules are involved in fires .

What is cadmium chloride activation?

The discovery of the cadmium chloride (CdCl2) activation process was the key innovation responsible for elevating device performance above 15% and attracting commercial interest in the early 1990's .

Are CdTe photovoltaics toxic?

The majority of contemporary Si modules utilize polymer/plastic backsheets which can also release toxic and carcinogenic substances under conditions of incomplete combustion. It is important to consider such secondary risks of CdTe photovoltaics not in isolation but in the context of other points of comparison.
