“…Numerical simulation is of a great interest for understanding the impact of different physical parameters on cell performance, it minimizes the cost of manufacturing prototypes, it makes it possible to design different solar cells based on crystalline, polycrystalline and amorphous materials [21][22] and offers the opportunity to study the influence of each layer of the cell in the case of interdependent parameters.…”

The authors have developed a simple, cheap and reproducible technology for obtaining thin-film heterostructures based on CdTe with a given surface morphology during vacuum deposition, which contributes to their low cost [1, 2]. The critical dimensions (thicknesses) of individual layers of the heterostructure were substantiated, a simulation was performed and a wide range of optical properties was investigated [3]. It is shown that for the deposited CdS / CdTe heterostructure on glass it is possible to obtain an efficiency of 15.8%. Given that thin films are relatively new systems, their study can offer much wider opportunities for technological improvement of photovoltaic energy converters. According to the analysis of modern literature data, the efficiency can be increased by performing deposition on ITO films and introducing nanoparticles of controlled sizes.

“…In order to assess more quantitatively the influence of E g grading, one can calculate the improvements with the help of an analytical approach (according to the procedure in [51,51,52,58]) which is based on the analysis of a device structure with a linear concentration gradient in the absorber towards the back contact. With the SCAPS numerical simulation approach (according to procedure in [59][60][61]), one can flexibly calculate the changes for linear front and back surface graded absorber structures (appropriate absorption input data are needed).…”

Das Ziel der Arbeit besteht darin, optimierte Absorber für das Dünnschicht Solarzellensystem Cu(In,Ga)(S,Se)2 mit Hilfe von industrienahen Prozessen herzustellen. Der industrienahe zweistufige Herstellungsprozess beinhaltet das Aufbringen von metallischen Vorläuferschichten (Kathoden zerstäubung & thermische Verdampfung) und die Bildung des Chalkopyrit Absorbers in Folge des thermischen Ausheizschrittes. Der gezielte Einbau von Konzentrationsgradienten bestehend aus Ga/In und Se/S wird werkstoffseitig am Absorber strukturell analysiert und für die elektronischen Eigenschaften der Solarzelle optimiert. Zur Justage des Ga/In Profils werden sowohl das optimierte Temperaturprofil als auch ein Überangebot an Chalkogenen verwendet. Für die Einstellung des Se/S Profils im Chalkopyrit dienen das Ausgangsverhältnis sowie ein nachträglicher S Einbau (Erweiterung auf einen drei-stufigen Prozess). Um den Rückkontakt der Solarzelle vor den aggressiven Chalkogenen während des Prozesse...

“…AFORS-HET (Automat For Simulation of HETero-structures) has been developed by a group from the Hahn-Meitner Institute of Berlin. It is used in simulating hetero-junction in solar cells [10] and provides a convenient way to evaluate the role of the various parameters present in the fabrication process [11,12]. In this paper, with the purpose of reducing the cost furthermore and promoting the performances of crystalline silicon solar cells, we optimize the doping concentrations and the thicknesses of the different layers of the solar cell.…”
