Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites
Advanced Materials, EarlyView.Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

AbstractThin‐film flexible photovoltaics are paving the way to low‐cost electricity. Organic, inorganic and organic–inorganic solar cells are deposited over flexible substrates by high‐throughput (often roll‐to‐roll printing) technologies to afford lightweight, economic solar modules that can be integrated into, not installed on, various surfaces ...

Projections show that worldwide energy consumption will increase by about 50% from 5.32×102° J to 7.80×1020 J within the next 30 years. New energy sources must be made accessible to ensure that the rising energy requirements are met. In this context, organic solar cells (OSCs) show great promise to reduce costs as well as energy consumption during ...

Reporting solar cell efficiencies in Solar Energy Materials and Solar Cells
Solar Energy Materials and Solar Cells, 2008Abstract In order to improve the accuracy, validity, reliability and reproducibility of reported power conversion efficiencies for solar cells, the journal, Solar Energy Materials and Solar Cells (SOLMAT), wishes to define how power conversion efficiencies should be reported. This expands upon what is specified in our Guide for Authors.

Thin film solar cells, ∼1 μm thick, have been fabricated from amorphous silicon deposited from a glow discharge in silane. The cells were made in a p-i-n structure by using doping gases in the discharge. The best power conversion efficiency to date is 2.4% in AM-1 sunlight.

Journal of Crystal Growth, 1975
This paper is intended to give an overview of the applications of epitaxial growth to photovoltaic solar cells. In order to introduce those operating parameters which can be improved by epitaxy, we begin by describing how a solar cell functions. Then we discuss the contribution of epitaxial growth to higher cell performance through improved crystalline

Abstract Semiconductor liquid junction solar cells reach 12 per cent solar to electrical and similar solar to chemical (hydrogen) conversion efficiency when made with single crystal semiconductors; they retain 2 3 of this efficiency when made with thin, chemically formed, polycrystalline semiconductor films.
