Is bi-maximal mixing compatible with the large angle MSW solution of the solar neutrino problem? [PDF]

Phys.Rev.D59:077301,1999, 1998
It is shown that the large angle MSW solution of the solar neutrino problem with a bi-maximal neutrino mixing matrix implies an energy-independent suppression of the solar nu_e flux. The present solar neutrino data exclude this solution of the solar neutrino problem at 99.6% CL.

Solar Neutrinos: Where We Are, Where We Are Going [PDF]

Astrophys.J.467:475-484,1996, 1995
This talk answers a series of questions. Why study solar neutrinos? What does the combined standard model (solar plus electroweak) predict for solar neutrinos? Why are the calculations of neutrino fluxes robust? What are the three solar neutrino problems? What have we learned in the first thirty years of solar neutrino research?

History of Solar Neutrino Observations [PDF]

arXiv, 2022
The first solar neutrino experiment led by Raymond Davis Jr. showed a deficit of neutrinos relative to the solar model prediction, referred to as the "solar neutrino problem" since the 1970s. The Kamiokande experiment led by Masatoshi Koshiba successfully observed solar neutrinos, as first reported in 1989.

Do the KamLAND and Solar Neutrino Data Rule out Solar Density Fluctuations? [PDF]

Phys.Rev. D68 (2003) 013006, 2003
We elucidate effects of solar density fluctuations on neutrino propagation through the Sun. Using data from the recent solar neutrino and KamLAND experiments we provide stringent limits on solar density fluctuations. It is shown that the neutrino data constrains solar density fluctuations to be less than beta = 0.05 at the 70 % confidence level, where ...

Influence of passivating interlayers on the carrier selectivity of MoOx contacts for c-Si solar cells

EPJ Photovoltaics
The application of molybdenum oxide (MoOx) as a hole-selective contact for silicon-based solar cells has been explored due to superior optical transmittance and potentially leaner manufacturing compared to fully amorphous silicon-based heterojunction ...

Plasma-Assisted N2O Oxidation (PANO) in an Industrial Direct Plasma Reactor for TOPCon Production

SiliconPV Conference Proceedings
Plasma-Enhanced Chemical Vapor Deposition (PECVD) is an attractive tool for TOPCon production, as it enables uniformly in situ doped amorphous silicon (a-Si) and dielectric layer depositions with high throughput. However, a lean process requires in situ

Reduction of Scarce Materials in Silicon Heterojunction Solar Cells and Implications on the Performance in the Field

SiliconPV Conference Proceedings
In the first part of this work the potential to save silver for n-type silicon heterojunction solar cells was investigated. Cells were produced with varied frontside screen opening (30-50 µm).

Stable reverse bias or integrated bypass diode in HIP‑MWT+ solar cells

EPJ Photovoltaics, 2022
The Metal Wrap Through+ (HIP-MWT+) solar cell is based on the PERC concept but features two additional electrical contacts, namely the Schottky contact between p-type Si bulk and Ag n-contact and the metal-insulator-semiconductor (MIS) contact on the ...

Cutting Indium Usage by 60% in SHJ-Modules Maintaining High Efficiency

SiliconPV Conference Proceedings
In this work the impact of reducing the Indium consumption for SHJ cells and modules is investigated. Optical simulations show that thinner Indium Tin Oxide (ITO) layers can be used on module level with minor reflection losses while on cell level losses

Solar Models: current epoch and time dependences, neutrinos, and helioseismological properties [PDF]

Astrophys.J.555:990-1012,2001, 2000
We calculate accurate solar models and report the detailed time dependences of important solar quantities. We use helioseismology to constrain the luminosity evolution of the sun and report the discovery of semi-convection in evolved solar models that include diffusion.
