Photovoltaics (PVs) consists of the harvesting of energy from sunlight and its conversion into electrical power. This technology is being increasingly recognized as one of the key components in our future global energy scenario. Limited fossil fuel resources and steadily increasing costs of supplying fossil fuels to the market induce a natural limit where renewable energies will begin to kick i...

Organic photovoltaic cell (OPV) has emerged as a new competitor to inorganic material-based solar cells, due to its potential application in large area, printable, and flexible solar panels. In particular, OPV cells with bulk heterojunction architecture (BHJ), in which the photoactive layer consists of a bicontinuous blend of an electron donor and an electron acceptor, has allowed power convers...

In this work, a newly fabricated organic solar cell based on a composite of fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) and regioregular poly (3-hexylthiophene) (P3HT) with an added interfacial layer of AgOx in between the PEDOT:PSS layer and the ITO layer is investigated and an equivalent circuit model is proposed for the device. Incorporation of the AgOx interfacial...

fossil fuel reserves is causing major changes in atmospheric carbon dioxide and associated climate change. Clearly, this is an untenable situation and alternative renewable energy sources must be found. The concept of harvesting the sun’s energy to create electrical power is an obvious answer and the principles of ‘photovoltaics’ (PV) (the direct conversion of ‘photons to volts’) have been demo...

today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. one of the almost endless and pure energy which have been paid attention over the years is the solar energy. solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. significant improvement has been made...

In this research work, numerical simulations are performed to correlate the photovoltaic parameters with various internal and external factors influencing the performance of solar cells. Single-diode modeling approach is utilized for this purpose and theoretical investigations are compared with the reported experimental evidences for organic and inorganic solar cells at various electrical and t...

Inorganic–organic hybrid structures have become innovative alternatives for next-generation dye-sensitized solar cells, because they combine the advantages of both systems. Here, we introduce a layered sandwich-type architecture, the core of which comprises a bicontinuous three-dimensional nanocomposite of mesoporous (mp)-TiO2, with CH3NH3PbI3 perovskite as light harvester, as well as a polymer...
