This comprehensive review discusses methods that have been used for the thermal
management of photovoltaic modules. Particular attention has been paid to the use of phase …

To achieve high efficiency perovskite solar cells (PSCs) based on α‐phase formamidinium
lead iodide (FAPbI3), addition of methylammonium chloride (MACl) in the precursor solution …

The origin of Urbach energy (EU) in organic semiconductors and its effect on photovoltaic
properties remain a topic of intense interest. In this letter, we demonstrate quantitative …

To gain insight into the properties of photovoltaic and light-emitting materials, detailed
information about their optical absorption spectra is essential. Here, we elucidate the …

The variation of dielectric constant (εr) in the low-frequency region (∼ 106 Hz) in Hf-
substituted BaTiO3 has been modelled considering the electronic disorder in the form of …

Magnetite and maghemite multicore nanoflowers (NFs) synthesized using the modified
polyol-mediated routes are to date among the most effective nanoheaters in magnetic …

We report the analysis of the Urbach effect in the absorption spectra of the undoped ZnO thin
films. The absorption coefficients of the ZnO thin films show the exponential rise, also known …

Temperature dependent diffuse reflectance spectroscopy measurements were carried out
on polycrystalline samples of BaTiO 3 across the tetragonal to cubic structural phase …

The radiative recombination limit of photovoltaic power conversion under one sun terrestrial
illumination is calculated for solar cells with lateral fluctuations of the band-gap energy. A …

Photoluminescence (PL) of Fe 3 O 4 nanoparticle was observed from the visible to near-
infrared (NIR) range by laser irradiation at 407 nm. PL spectra of∼ 10 nm diameter Fe 3 O 4 …
