Renewable Energy Generation

Solar cells are one of the most popular renewable energy generation technologies, because they are reliable, low operating and maintenance costs, to conclude without any moving parts and is a boundless source of energy. In any solar cell can avoid mechanical vibrations, which may produce the solar cell glass, damage to the inner structure. In order to determine the influence of mechanical vibrations of the solar cell structure was carried out theoretical and experimental modal analysis. The study found dangerous solar cell frequencies and their deformation and optimize the method of attachment which provides a better solar cell stability. Saulės elementai – vieni populiariausių atsinaujinančių energijos gavybos technologijų, nes jie patikimi, jų mažos eksploatavimo ir priežiūros išlaidos, šie elementai sudaryti be jokių judančių dalių ir yra beribis energijos šaltinis. Bet saulės elementas neišvengia mechaninių virpesių, kurie gali įskelti saulės elemento stiklą, pažeisti vidinę konstrukciją. Siekiant nustatyti mechaninių virpesių įtaką saulės elemento konstrukcijai, buvo atliktos teorinės ir eksperimentinės modalinės analizės. Tyrime buvo rasti pavojingi saulės elemento dažniai ir jų deformacijos, rastas optimalus tvirtinimo būdas, kuris suteikia geresnį saulės elemento stabilumą.

Limiting Values

The paper discusses and compares the Lambertian limits for light trapping (LT) in GaAs active layer based thin film solar cells as described by different mathematical theories and expressions. The Lambertian limits for thin film GaAs solar cell provide the maximum efficiency that can be achieved through LT structures and also indicate the advantage that these structure can provide for the design of GaAs thin film solar cell structure. The purpose to discuss difference Lambertian limit expressions is to understand and predict, which limiting benchmark value is more suited for nano LT structures based GaAs active material solar cells, considering GaAs material properties. The paper also compares these calculated limiting values with different nano LT structures including photonic crystal structures based designs proposed by the author. The aim is to check how much close a particular proposed structure is to the Lambertian values, so that we can predict that which is more suitable design to get best efficiency out of the single junction GaAs material based structure. The paper discussed the three Lambertian theories including that of Yablonovitch, Green and Schuster.

The Matrix

In this paper, photovoltaics (PV)- or solar cells based on two types of nanoparticles have been investigated. The suggested four-layer solar cell model consists of metallic nanoparticle (Ag–Au) layers that are Si-based and covered by SiN. The transmission and reflection of the incident light on the structure model have been computed for different physical parameters of the structure. Higher transmission and lower reflections have been obtained leading to higher efficiency of the solar cells. The matrix model is used, and the numerical results obtained by MAPLE Software Program. The obtained results confirm that the nanoparticle solar cell structure can effectively enhance the efficiency of such structure model.

Abstract Backround: In this study, we report for the first time that the addition of an intrinsic layer to the a-Si: H p-i-n solar cell structure greatly enhances the conversion efficiency. The a-Si: H p-i-n solar cells were grown using Plasma Enhanced Chemical Vapor Deposition (PECVD) techniques on the Indium Tin Oxide (ITO) substrate and added an intrinsic layer with the p-i1-i2-n structure in order to prevent sunlight energy from being absorbed the first intrinsic layer can be absorbed by the second intrinsic layer. Result The a-Si: H p-i-n and p-i1-i2-n solar cells were characterized including optical properties, electrical properties, surface morphology, thickness, band-gap using Ellipsometric Spectroscopy (ES). Furthermore, from the optical constant and thin film thickness, the reflectance and transmittance of each sample were obtained. The p-i-n and p-i1-i2-n samples show good transparency in the infrared region and this transparency decreases in the visible light region shows an interference pattern with a sharp decrease in transmission at the absorption edge and the performance of solar cells (curve I-V) measured by use sun simulator and sunshine. Conclussion: Our results show that there is a very good increase in the efficiency of the a-Si: H p-i1-i2-n solar cells by 58.6% of the original p-i-n structure.

AbstractIn this manuscript, we give an overview of the main insights into our growth procedure for kesterite solar cells and show the possibilities that are provided by this approach. The importance of using Cu–Sn alloy instead of elemental Sn and Cu in the precursor is shown. We discuss how the alloy approach stabilises the composition and helps guide the process along a preferred reaction pathway. A summary of our previously reported findings in the context of our latest results on kesterite solar cells prepared from Cu–Sn alloyed precursors is drawn. The positive impact of an alloy precursor configuration on the formation pathway, process control, and process resilience is demonstrated. Furthermore, a new optimisation strategy for kesterite, based on the reported pathway, is discussed, including a smooth phase transition from Cu-rich to Cu-poor kesterite. Finally, we demonstrate results on buffer optimisation and the application of a promising hybrid buffer configuration of CdS/Zn(O,S), which can reduce the optical losses in the solar cell structure.
