Organic-inorganic halide perovskite solar cells have enormous potential to impact the existing photovoltaic industry. As realizing a higher conversion efficiency of the solar cell is still the most crucial task, a great number of schemes were proposed to minimize the carrier loss by optimizing the electrical properties of the perovskite solar cells. Here, we focus on another significant aspect ...

Recently, we correlated the inferred structure of the solar chromospheric plasma topography with solar wind velocity and composition data measured at 1 AU. We now offer a physical justification of these relationships and present initial results of a empirical prediction model based on them. While still limited by the fundamentally complex physics behind the origins of the solar wind and how its...

In this paper, a solar based hydrogen production in the city of Tehran, the capital of Iran is simulated and the cost of produced hydrogen is evaluated. Local solar power profile is obtained using TRNSYS software for a typical parking station in Tehran. The generated electricity is used to supply power to a Proton Exchange Membrane (PEM) electrolyzer for hydrogen production. Dynamic nature of s...

Solar elastosis is a degenerative condition of elastic tissue in the dermis due to prolonged sun exposure. There are a variety of clinical manifestations of solar elastosis. In its most common form, solar elastosis manifests as yellow, thickened, coarsely wrinkled skin. We report two uncommon cases of severe solar elastosis with a papular morphology. Its presentation can closely mimic a host of...

After the Delhi High Court judgment on reading down Section 377 Indian penal code, many individuals of alternate sexuality are wanting to come out to themselves and significant others in their lives. In this process, they often turn to psychiatrists seeking help. However the past of this specialty wherein homosexuality and other sexualities were considered a disease still haunts it with anecdot...

Atmospheric and solar neutrino experiments have been contributing substantially to the understanding of the neutrino masses and mixing angles. Recently, several new data have been presented from solar and atmospheric neutrino experiments. These new data are discussed together with the constraints on oscillation parameters. There are still exciting, future solar and atmospheric neutrino studies....

Solar energy conversion to electricity through photovoltaics or to useful fuel through photoelectrochemical cells was still a main task for research groups and developments sectors. In this article we are reviewing the development of the different generations of solar cells. The fabrication of solar cells has passed through a large number of improvement steps considering the technological and e...

Organic or ‘plastic’ solar cells are attractive for solar photoelectric energy conversion applications where low cost (such as large area), lightweight, and flexible shape are desired. The photoelectric power conversion efficiencies of currently reported organic/polymeric photovoltaic materials are still relatively low (typically less than 10% under AM 1.5 and one Sun intensity), and the three ...
