The organic/silicon (Si) hybrid heterojunction solar cells (HHSCs) have attracted considerable attention due to their potential advantages in high efficiency and low cost. However, as a newly arisen photovoltaic device, its current efficiency is still much worse than commercially available Si solar cells. Therefore, a comprehensive and systematical optoelectronic evaluation and loss analysis on...

Perovskite-silicon tandem solar cells have attracted much attention to photovoltaic community because of their high efficiency via easy fabrication methods and availability precursor material abundant in nature. The properties both perovskite silicon meet ideal cell standards such as light absorption potential, long carrier diffusion length fast charge separation process. Semi-transparent with ...

With the success of silicon (Si) solar cell technology, research and development on higher efficiency multijunction cells is gaining much attention. Tandem with a perovskite top Si bottom show particular potential. However, optical modeling such devices complicated by broad range length scales involved; optically thin layers nanoscale features require some version wave optics or even full field...

The performance of a solar cell is critically dependent on absorption of incident photons and their conversion into electrical current. This report describes research efforts that have been directed toward the use of nanoscale surface texturing techniques to enhance light absorption in Si. This effort has been divided into two approaches. The first is to use plasma-etching to produce random tex...

We review laser applications in thin-film photovoltaics (thin-film Si, CdTe, and Cu(In,Ga)Se2 solar cells). Lasers are applied in this growing field to manufacture modules, to monitor Si deposition processes, and to characterize opto-electrical properties of thin films. Unlike traditional panels based on crystalline silicon wafers, the individual cells of a thin-film photovoltaic module can be ...

The effects of silicon solar cell with presence of double layer anti-reflecting coating SiO and Si N 2 3 4 were discussed in this paper. The comparison were varied using different incident light of 90°, 60° and 30° to study the performance of the photovoltaic efficiency and external quantum efficiency of SiO /Si N silicon solar 2 3 4 cell. The solar cell structure was modelled by using Silvaco ...

We have achieved significant accomplishments on the developing of high-efficiency thin film multi-junction solar cell with nano-scale light management. The highlights include: (1) Developed a computational tool for the detailed balance analysis of nanophotonic structures showing that absorption in a solar cell at all angles is sufficient to calculate and understand the fundamental behavior of n...

The presence or absence of variations in the mass-independent abundances of Si isotopes in bulk meteorites provides important clues concerning the evolution of the early solar system. No Si isotopic anomalies have been found within the level of analytical precision of 15 ppm in Si/Si across a wide range of inner solar system materials, including terrestrial basalts, chondrites, and achondrites....
