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 ...

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 ProceedingsIn 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

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

Advanced Engineering Materials, EarlyView.The fabrication and post‐treatment via solvent annealing of poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate‐based electrodes using spray deposition in a roll‐to‐roll setup are presented. The decrease in sheet resistance and its correlation with nanostructure and molecular structure in the electrodes as a function of the processing parameters is ...

Flexible Cu2ZnSn(S,Se)4 solar cells with over 10% efficiency and methods of enlarging the cell area
Nature Communications, 2019 Flexibility and homogeneity are preferred properties for the kesterite solar modules to compete with silicon counterparts. Here, Yang et al. achieve these properties by designing a thin and multi-layered precursor structure and at the same time increase ...

Thermal model in digital twin of vertical PV system helps to explain unexpected yield gains
EPJ Photovoltaics, 2023 The business case of novel integrated applications of solar energy is often regarded as a straightforward extrapolation of standard solar parks. But when the design of the solar park is remarkably different from typical solar parks, the operating ...
