Interface tailoring is an effective approach towards high performance Graphene/Silicon Schottky-barrier solar cells. Inserting a thin graphene oxide (GO) interfacial layer can improve the efficiency of graphene/silicon solar cells by >100%. Further performance optimization leads to 12.3% of power conversion efficiency (PCE). To date, a record PCE has been achieved on the same device level.

Photovoltaic energy presents environmental advantages; however, these advantages are limited by the cost of manufacturing solar cells and in many cases, scarce or dangerous materials are incorporated. Therefore, the use of natural dyes from mortiño (Vaccinium floribundum) as sensitizers in solar cells is proposed. The dyes were extracted by maceration in acidified methanol (HCl, citric acid and trifluoroacetic acid TFA) and were characterized by High-Performance Liquid Chromatography (HPLC), Thin-Layer Chromatography (TLC) and spectrometric methods (UV-Vis, IR and MS-MALDI). The construction and characterization of cells were in standard conditions. The study confirms that pigments in mortiño are flavonoids of the anthocyanidin group as: cyanidin-3-galactoside, and cyanidin-3-arabinoside. The efficiency of solar cells was between 0.18–0.26%; the extraction with TFA in methanol leads to the best performance. Although they have low power conversion efficiency, mortiño dyes could be an alternative to artificial sensitizers for solar cell technologies because they are harmless and abundant substances.

Purpose The aim of this paper is to apply a watery infrared filter for silicon solar cell efficiency enhancement in Kerman province of Iran as a talent region for solar energy production. Design/methodology/approach With this research, the water is applied as a filter for silicon solar cells in different volumes and thicknesses. Findings The obtained results showed that using various amounts of water could be a suitable choice for increasing the efficiency of silicon solar cells. Originality/value Other wavelength regions just cause the increase in the entropy and decrease in the efficiency. With this research, the water is applied as a filter for silicon solar cell in different volumes and thickness. The obtained results showed that using different thicknesses of water could be suitable choice for increasing the efficiency of silicon solar cell.

Amorphous Silicon Solar Cell

AbstractSeveral promising new methods for amorphous silicon solar cell preparation involve high substrate temperatures and/or very reactive atmospheres. When incorporated into solar cells, the performance of these layers has often been less than expected due to enhanced diffusion and/or chemical reactions. This poor performance results from the harsh deposition environments. Deleterious effects include darken of TCO coated glass substrates due to hydrogen diffusion to and hydrogen reduction at the TCO interface when solar cells are prepared in the p-i-n deposition sequence. Alternatively, the deposition of TCO layers onto amorphous layers also involves rather harsh oxidizing conditions that have a deleterious effect on the top most amorphous silicon-based p-layers. Strategic use of blocking layers results in remarkably improved solar cell performance. A thin Cr layer (probably becoming Cr2O3) shows ability to improve the performance of both n-ip and p-i-n solar cells by inhibiting both O and H diffusion.

In this work, a silicon solar cell HIT (heterojunction with intrinsic thin-layer) a-Si:H(n)/a-Si:H(i)/c-Si(p) was simulated using AFORS-HET software. The influence of layer thickness and temperature of the solar cell under study on its photovoltaic characteristics is discussed. When optimizing the above characteristics, its effectiveness reaches a value of 19.1%. The results obtained are the foundation for further scientific and technological research on the development of highly efficient silicon solar cells.

— Utilization of solar photovoltaic is increasing dayby day to reduce dependence on the power grid. Decompositionof 1st and 3rd generation silicon solar cells not only depends uponthe plastic and other materials but also the hazardous elementmainly used as their character on the bases of which they arecategorized as 1st , 2nd and 3rd contemporaries solar cells. Theseingredient are mostly carcinogenic and some of them having lifespan of more than 100 years. After abjection of solar cells, theyremain in the soil for many years and cause serious problem toland environment and also responsible for causing carcinogenicdisease in human and other living beings. This paper exploresdecomposition rates of the chemical element mainly used in 1stand 3rd generation solar cells throughout the past years, possibleenvironmental and health effects by the hazardous elements usedin them typically silicon (atomic number 14) and focusing onpossible suggested solutions or alternatives.
