The enhanced optoelectronic properties are shown to scale here with the degree of Ag-alloying in ACZTSe. The impacts of these effects on device performance are discussed, with improvement in average device performance/open-circuit voltage reported for \{ACZTSe\} (5\%-Ag) absorbers relative to \{CZTSe\} absorbers with similar band gap. These initial results are promising for the Ag-alloyed \{ACZTSe\} material system as \{VOC\} limitations are the primary cause of poor device performance in kesterite solar cells, and cation substitution presents a unique method to tune the defect properties of kesterite absorbers. Herein, nanoparticle synthesis and large-grain \{ACZTSe\} absorber formation is described followed by material and optoelectronic characterization. Additionally, \{RTP\} processing is presented to achieve fully selenized large-grain chalcogenide absorbers from sulfide nanocrystal inks.}, keywords = {Characterization}, issn = {0927-0248}, doi = {http://dx.doi.org/10.1016/j.solmat.2015.10.039}, url = {http://www.sciencedirect.com/science/article/pii/S0927024815005504}, author = {Charles J.

It calculates the losses for any angle of incidence within seconds, where the short computation time is achieved by decoupling the ray tracing from the Fresnel equations. Amongst other morphologies, OPAL 2 can be used to assess the random-pyramid texture of c-Si solar cells, or the {\textquoteleft}isotexture{\textquoteright} of mc-Si solar cells, and to determine (i) the optimal thickness of an antireflection coating with or without encapsulation, (ii) the impact of imperfect texturing, such as non-ideal texture angles, over-etched isotexture, and flat regions, and (iii) the subsequent 1D generation profile in the Si.
