We report the performance of perovskite solar cells (PSCs) with an electron transport layer (ETL) consisting of a SnO2 thin film obtained by electrochemical deposition. The surface morphology and thickness of the electrodeposited SnO2 films were closely related to electrochemical process conditions, i.e., the applied voltage, bath temperature, and deposition time. We investigated the performanc...

Silicon nanowire (SiNW) arrays were produced by electroless method on polycrystalline Si substrate, in HF/ AgNO3 solution. Although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. In order to study the influence of etching time (which affects the SiNWs length) on d...

Irradiation-Dependent Photovoltaic Parameters In article number 2300043, Peter Müller-Buschbaum and co-workers present a detailed analysis of irradiation-dependent photovoltaic parameters perovskite organic solar cells exposed to space conditions. The post-flight characterization elucidates the impact sole transport versus rocket launch, flight, reentry stress.

The Kyoto Protocol for preventing global warming was adopted at the Conference of Parties III (COP3) of The United Nations Framework Convention on Climate Change held in Kyoto, Japan in December 1997. This Protocol established numerical targets for reducing greenhouse gas emissions in 2010 for each of the participating industrialized countries. In February 2005, the Kyoto Protocol was enacted a...

A large amount of redundant energy gained from incident solar is dissipated into the environment in form low-grade heat, which significantly reduces and limits performance photovoltaic cells, so removing or storing heat converting it back available thermal a promising way to improve utilization energy. new combined water-based photovoltaic-thermophotovoltaic system embedded phase change materia...

The photoelectric power conversion efficiency of polymer solar cells is till now, compared to conventional inorganic solar cells, still relatively low with maximum values ranging from 7% to 8%. This essentially relates to the existence of exciton and charge carrier loss phenomena, reducing the performance of polymer solar cells significantly. In this paper we introduce a new computer simulation...

The introduction of a low band-gap oligomer, oligo(benzo[1,2,5]thiadiazole-alt-3,3'''-dihexylquaterthiophene) (BT4T) improved the performance of P3HT:PCBM bulk heterojunction organic photovoltaic cells due to improved UV-vis absorption and increased P3HT crystallinity.

In this review uses of Polymer electrets as an important class of organic materials finding its use in variety of electronic and electrical engineering industry ranging from photovoltaic cells, transducers, dosimeters and other applications are discussed.

Porphyrins bearing a polyaromatic or a heterocyclic group are prepared to study their fundamental and photovoltaic properties. Solar cells sensitized with a fluorene-modified porphyrin outperform other dyes in the series, reaching ~90% efficiency of N719 dye.

The Shockley-Queisser limit describes the maximum solar energy conversion efficiency achievable for a particular material and is the standard by which new photovoltaic technologies are compared. This limit is based on the principle of detailed balance, which equates the photon flux into a device to the particle flux (photons or electrons) out of that device. Nanostructured solar cells represent...
