Glass Frit Dissolution Influenced by Material Composition and the Water Content in Iodide/Triiodide Electrolyte of Dye-Sensitized Solar Cells

open access: yesInternational Journal of Photoenergy, 2013
To ensure long-term stable dye-sensitized solar cells (DSCs) and modules, a hermetic sealing is required. This research investigates the chemical stability of I-/I3- redox electrolyte and four different glass frits (GFs).

A thermodynamic cycle for the solar cell [PDF]

open access: yesAnnals of Physics, 2017
A solar cell is a heat engine, but textbook treatments are not wholly satisfactory from a thermodynamic standpoint, since they present solar cells as directly converting the energy of light into electricity, and the current in the circuit as maintained by an electrostatic potential.

Facile Synthesis of CuxS Electrocatalysts for CO2 Conversion into Formate and Study of Relations Between Cu and S with the Selectivity

open access: yesAdvanced Functional Materials, EarlyView.
Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

Guidelines for the bandgap combinations and absorption windows for organic tandem and triple-junction solar cells [PDF]

open access: yes, 2012
Organic solar cells have narrow absorption windows, compared to the absorption band of inorganic semiconductors. A possible way to capture a wider band of the solar spectrum-and thus increasing the power conversion efficiency-is using more solar cells ...

Influence of deposition temperature of thermal ALD deposited Al2O3 films on silicon surface passivation

open access: yesAIP Advances, 2015
The effect of deposition temperature (Tdep) and subsequent annealing time (tanl) of atomic layer deposited aluminum oxide (Al2O3) films on silicon surface passivation (in terms of surface recombination velocity, SRV) is investigated. The pristine samples

Two-Terminal Tandem Solar Cells based on Perovskite and Transition Metal Dichalcogenides [PDF]

open access: yesarXiv, 2021
Perovskite solar cells have shown power conversion efficiencies (PCE) comparable to cystalline silicon solar cell despite involving low-temperature, solution based synthesis processes outside clean room environment. As the theoretical PCE of a perovskite solar cell with band gap 1.55 eV is capped to 33 % due to Shockley-Queisser limit, tandem ...

Multiscale approaches to high efficiency photovoltaics

open access: yesRenewable Energy and Environmental Sustainability, 2016
While renewable energies are achieving parity around the globe, efforts to reach higher solar cell efficiencies becomes ever more difficult as they approach the limiting efficiency.

Influence of radiation on the properties of solar cells [PDF]

open access: yesNuclear Technology and Radiation Protection, 2011
The wide substitution of conventional types of energy by solar energy lies in the rate of developing solar cell technology. Silicon is still the mostly used element for solar cell production, so efforts are directed to the improvement of physical ...
