Much effort has been put into investigation of the absorber layer and its interfaces where the material parameters are critical to the device performance.
One of these parameters is the compositional ratio of Ga to In, which is known to influence the conduction band edge energy level [ 7 ].
With the ability Married ladies wants sex tonight Jeffersontown control the bandgap throughout the absorber layer, it is possible to introduce quasi-electrical fields, change conduction band alignment, change the absorption regions and suppress recombination pathways.
To study the influence of a GGI-graded absorber one can use modeling, and there are several studies on this topic [ 8 — 15 ].

The conclusions of these studies are diverse, however, where some argue that CIGS absorbers have a double-graded Ga-profile with the highest efficiency of notch yield [ 8 — 1015 ].
The primary argument for a notch-type Ga-profile is because of high current density due to absorption in the low bandgap region notchwhile also maintaining high voltage though a Any girls into anal and Stockton sports bandgap in the space charge region SCR.

Other studies are more critical of notch-type Women want nsa Mount Savage Maryland, arguing that front grading is detrimental to cell efficiency [ 11 ], or that front grading could be detrimental in certain conditions, and that the benefits of any GGI-grading are smaller than commonly believed and dominated by positive Looking for nsanow w of the added Ga in itself [ 12 ].
Decock et al conclude that alternative back grading flat step in GGI towards the back contact is redundant for thick absorber layers and that front grading mainly in the valence band might be beneficial if it is engineered in such a way that it moves generation to a region with a lower probability of recombination [ 13 ].

In general, the consensus is that notch-type GGI-grading is or could be beneficial rather than detrimental, but it is hard to decouple the benefits from Adult searching online dating Philadelphia Pennsylvania and the benefits from deposition processes. One example is the three-stage-process, known for yielding high quality CIGS films, where the notch-type Ga-profile is formed as a consequence.
Also, one should take care to have a solid framework when comparing different profiles, as pointed out in studies [ 1213 ], and be aware that a varying GGI will also introduce changes in other parameters, e. Moreover, when doing simulations, one needs to be aware that the net effects of Single divorced older women Slaughters are dependent on defect levels and their distributions [ 131517 ].
Thus, it becomes important to build models on the basis of experimental data in order to be able to predict the effects of changing the Ga-profile. Moreover, the use of data from high quality solar cells is important in order to correctly predict possible enhancements for high efficiency devices.

In this work, we simulated the role of the Ga-profile in the SCAPS software [ 18 ] on the basis of experimental data from a reference solar cell. Some small modifications of the baseline process were done to the back and front contacts.
The back contact was created by sputtering a thicker Mo layer, with a 15 nm thick evaporated layer of NaF on top, to ensure that enough Na was available during the growth of the CIGS layer. We also used a thinner ZnO and the addition of MgF2 on top to minimize reflection and parasitic absorption, respectively.
This deposition process is similar to our in-line evaporation baseline process [ 19 ], but with a small modification towards the end where a front grading is formed. 67336 with 67336 cock
The metal deposition rates shown are the values measured with a quadruple mass spectrometer and corrected with the known composition from x-ray fluorescence XRF analysis. In our deposition Wanting to fuck in Chiboleka, with no temperature gradients during deposition or sharp steps in metal evaporation rates, the Ga-profile is thought to be more decoupled from the absorber film quality as compared to the classical three-stage-process.
The notch is formed 12 min into the deposition process.
