We have developed the 3-dimensional optical model for thin film silicon solar cells (amorphous, microcrystalline, single or multijunction) with nanorough surfaces/interfaces. For these cells the external quantum efficiency, short circuit current, total reflectance and all absorption losses can be computed taking into account roughness, angular distribution of scattered light, thicknesses and ex...
Organic-inorganic hybrid tandem solar cells attract a considerable amount of attention due to their potential for realizing high efficiency photovoltaic devices at a low cost. Here, highly efficient triple-junction (TJ) hybrid tandem solar cells consisting of a double-junction (DJ) amorphous silicon (a-Si) cell and an organic photovoltaic (OPV) rear cell were developed. In order to design the T...
Metal oxide semiconductors are promising photoelectrode materials for solar water splitting due to their robustness in aqueous solutions and low cost. Yet, their solar-to-hydrogen conversion efficiencies are still not high enough for practical applications. Here we present a strategy to enhance the efficiency of metal oxides, hetero-type dual photoelectrodes, in which two photoanodes of differe...
In this article, we present a new paradigm for organometallic hybrid perovskite solar cell using NiO inorganic metal oxide nanocrystalline as p-type electrode material and realized the first mesoscopic NiO/perovskite/[6,6]-phenyl C61-butyric acid methyl ester (PC61BM) heterojunction photovoltaic device. The photo-induced transient absorption spectroscopy results verified that the architecture i...

We determine the limiting efficiency for monolithic tandem solar cells that employ crystalline silicon top-cell as well bottom cell. In such a design, extends over region of very high generation rate forms at front device. Consequently, design benefits from excess carrier density in top-cell, resulting voltage device is more than twice equally thick single junction cells. Considering Coulomb-en...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1628. 84 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-513-0229-4. The perovskite solar cell (PSC) is a recent contender with...
In this article, the effect of plasmonics properties of metal nanorods and nanoparticles on solar cell performance were investigated and simulated. Due to the classic solar cell disadvantages, it seems that a plasmonic solar cell is one of these methods. In plasmonic solar cells, because of plasmonic effect, a high electric field builds around metal nanoparticles so that high conversion efficie...
Dye-sensitized solar cells (DSCs) using the p-type semiconductor CuAlO2, in conjunction with a highly effective hole injecting dye and an iodide-triiodide-based electrolyte have been produced, demonstrating photocathodic behavior. An improved open-circuit voltage (VOC) of 333 mV was observed, compared to analogous devices using NiO, which can be explained by the CuAlO2 valence-band energy, whic...
The development of medium-bandgap solar cell absorber materials is of interest for the design of devices such as tandem solar cells and building-integrated photovoltaics. The recently developed perovskite solar cells can be suitable candidates for these applications. At present, wide bandgap alkylammonium lead bromide perovskite absorbers require a high-temperature sintered mesoporous TiO2 phot...
