5 Frequently Asked Questions about “Amount of alkali used in photovoltaic glass”
Do alkali elements play a role in photovoltaic materials?
1 Introduction Since the introduction of the alkali element sodium Na in the 1990's into the research of Cu(In,Ga)Se2 (CIGS) type solar cells, the investigation of the role of alkali elements in such photovoltaic materials has spawned a large number of studies and publications on that topic over the following decades, e.g. [2–5].
Which alkali element is most effective for CIGS solar cells?
From early experiments with other alkali elements by using al-kali fluoride precursors for doping of CIGS layers, it was concluded that Na is the most effective alkali element for increasing the efficiency of CIGS solar cells .
Do heavier alkalis improve diode quality?
A diode analysis reveals an improved diode quality for cells treat-ed with heavier alkalis. Furthermore, secondary ion mass spec-trometry (SIMS) measurements reveal a competitive mecha-nism induced within the class of alkali elements in the CIGS absorber induced by the alkali post deposition treatment.
How much efficiencies can be achieved by introducing two more alkali elements?
Again a whole new realm of scientific investigations was opened leading to a fast rise of record efficiencies by using this technique: 20.4% to 21.0% (EMPA: 20.4%, ZSW: 20.8%, Soli- bro 21.0% ). In this contribution we show how we have followed this logic even further by introducing two more alkali elements.
Is a gain in VOC a benefit for all alkali compounds?
In particular, one can see that there is, in fact, an additional benefit from going beyond potassium to rubidium and caesium. This gain in efficiency for all alkali compounds is due to a gain in Voc. However, the trend in Voc is not as consist-ent as in ETA since the gain in Voc for KF-PDT is higher than for RbF- or CsF-PDT.
