Accurate explicit equations for the fill factor of real solar cells:Applications to thin-film solar cells
(John Wiley & Sons Ltd, 2012-06-14)
Even within the simplest real solar cell model, the exact value of the fill factor (FF) is only computable by numerical calculations. Here, we perform approximations to the power-voltage curve given by the one-diode model ...
Design of diblock co-oligomers as low bandgap small molecules for organic solar cells
(2017-12-12)
The properties of a particular kind of small molecule that is built from two oligomers of different monomers, i.e. a diblock co-oligomer, as the electron donor in the active layer of organic solar cells are investigated ...
Toward stable solar hydrogen generation using organic photoelectrochemical cells
(American Chemical Society, 2015-03)
Organic photoactive materials are promising candidates for the generation of solar fuels in terms of efficiency and cost. However, their low stability in aqueous media constitutes a serious problem for technological ...
Theoretical evaluation of chemical substitutions along the main chain of poly(3-hexylthienylene-vinylene) for solar cell applications
(2018-02-01)
In order to improve the efficiency of bulk-heterojunction organic solar cells, one can try to optimize the active layer through the use of new materials that provide improvements in the parameters that influence the final ...
Electronic structure of polythieno[3,4-b]-thiophene-co-benzodithiophene (PTB7) derivatives for organic solar cell applications
(2016-06-01)
Among the new materials currently employed as electron donor element in active layers of organic solar cells (OSCs), PTB7 holds the best results. It has been extensively studied and now there is a search for new derivatives ...
Modifying electronic properties of ICBA through chemical substitutions for solar cell applications
(2017-08-01)
Fullerene derivatives are the most widely used type of acceptor material in the organic solar cells (OSCs) active layers, but there are still some problems to be overcome, such as increased solubility and adjustment of the ...
ORGANIC PHOTOVOLTAIC CELLS: HISTORY, PRINCIPLE AND TECHNIQUES
(Sociedad Chilena de Química, 2008)
Modeling of open-circuit voltage of phenyl-C61-butyric acid methyl ester-like based bulk-heterojunction solar cells
(2015-12-01)
New materials are currently being sought for use in active layers of bulk-heterojunction organic solar cells, and computational modeling plays an important role in this search. Although open circuit voltage (Voc) is one ...
Theoretical study of new potential semiconductor surfaces performance for dye sensitized solar cell usage: TiO2-B (001), (100) and H2Ti3O7 (100)
(Elsevier Science, 2017-12-31)
Hydrogen titanate (H2Ti3O7) and TiO2-B polymorph are potential surfaces identified experimentally in the last years, which need to be analyzed. To study their performance as surfaces for dye sensitized solar cells (DSSC), ...
