Silicon nanowire (SiNW) arrays show an excellent light-trapping characteristic and high mobility for carriers. Surface plasmon resonance of silver nanoparticles (AgNPs) can be used to increase light scattering and absorption in solar cells. We fabricated a new kind of SiNW/organic hybrid solar cell by introducing AgNPs. Reflection spectra confirm the improved light scattering of AgNP-decorated ...

The Si tandem solar cells composes of III-V, II-VI, chalcogenide and perovskite top bottom are very attractive for creation new markets. perovskite/Si thought to be one the most promising PV devices because high-efficiency low-cost potential. However, efficiencies with an efficiency 29.8% lower compared 39.5% III-V 3-junction 35.9% III-V/Si cells. Therefore, it is necessary clarify reduce sever...

A novel donor-acceptor type conjugated polymer based on a building block of 4,8-di(thien-2-yl)-6-octyl-2-octyl-5H-pyrrolo[3,4-f]benzotriazole-5,7(6H)-dione (TZBI) as the acceptor unit and 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)-benzo-[1,2-b:4,5-b']dithiophene as the donor unit, named as PTZBIBDT, is developed and used as an electron-donating material in bulk-heterojunction polymer solar cells. T...

We determine the limiting efficiency for monolithic tandem solar cells that employ crystalline silicon top-cell as well bottom cell. In such a design, extends over region of very high generation rate forms at front device. Consequently, design benefits from excess carrier density in top-cell, resulting voltage device is more than twice equally thick single junction cells. Considering Coulomb-en...

Multijunction Solar Cells To achieve sustainable development goals, the use of high-efficiency III-V//Si multi-junction solar cells is attracting attention for transport equipment such as electric vehicles and unmanned aerial vehicles. The issue that needs to be addressed expand reduce their production cost. In article number 2200198, Yasushi Shoji co-workers, propose a cost-reduction technology.

Solar photovoltaics based on synthetic halide perovskites have revolutionized solar energetics in the last decade. Since 2009 overall efficiency of sunlight-to-electricity conversion perovskite cells increases from 3.8% up to 25.5% (for thin-film single-junction cells) and more than 30% affordable tandem with top photovoltaic layer perovskite). On other hand, nanophotonics has made a huge progr...

Perovskite/silicon tandem photovoltaics is a promising technology to exceed the performance limit of single-junction solar cells. For utility-scale photovoltaic plants, trends and forecasts indicate that bifacial modules mounted on trackers will increasingly dominate market in next 20 years. In line with this roadmap, we investigate outdoor perovskite/silicon cells horizontal single-axis tracke...

In this article, we present a new paradigm for organometallic hybrid perovskite solar cell using NiO inorganic metal oxide nanocrystalline as p-type electrode material and realized the first mesoscopic NiO/perovskite/[6,6]-phenyl C61-butyric acid methyl ester (PC61BM) heterojunction photovoltaic device. The photo-induced transient absorption spectroscopy results verified that the architecture i...
