Advanced Studies on Dye-Sensitized Solar Cells
Universitat Jaume I (2013-05-13)The conversion of sunlight into electricity is one of the most promising energy sources because is renewable and available worldwide. Therefore, is desirable to develop low cost, stable and efficient photovoltaic devices ... -
Charge carrier transport and contact selectivity limit the operation of PTB7-based organic solar cells of varying active layer thickness
Royal Society of Chemistry (2013-08)In this work we study the different electrical loss pathways occurring during the operation of bulk heterojunction solar cells by using a variety of electrical and optical characterization techniques beyond the current ... -
Degradation analysis of perovskite solar cells doped with MABr3 via electrochemical impedance
Elsevier (2023)In this study, perovskite solar cells with a structure CsyFA1-xMAxCS0.05Pb(I1.05-xBrx)3, with X = 0 (no doping was added to the base structure CsFAPbI3) and X = 0.085 (CsFAPbI3 was doped with 8.5% MABr3) were prepared ... -
Small Perturbation Techniques for the Electronic Analysis of Perovskite Devices
Universitat Jaume I (2023-02-20)Metal-halide perovskites have emerged as a promising semiconductor material for a variety of potential applications, due to their intrinsic properties and their low-cost fabrication methods. Perovskite solar cells have ... -
Theory of the impedance of charge transfer via surface states in dye-sensitized solar cells
Elsevier (2010)The dynamics of trapping coupled with charge transfer is analysed in the frequency domain for a model of the dye-sensitized solar cell. We solve the steady state occupations of the surface state and the resulting recombination ...
