Journal ArticleDOI
Bandgap tuning of multiferroic oxide solar cells
Riad Nechache,Riad Nechache,Catalin Harnagea,Shun Li,Luis Cardenas,Wei Huang,Joyprokash Chakrabartty,Federico Rosei,Federico Rosei +8 more
TL;DR: Tuning the bandgap of multiferroic solar cells made from Bi2FeCrO6 is achieved by cationic ordering and is shown to dramatically improve their performance as discussed by the authors.
Journal ArticleDOI
Improved photovoltaic performance from inorganic perovskite oxide thin films with mixed crystal phases
Joyprokash Chakrabartty,Joyprokash Chakrabartty,Catalin Harnagea,Mert Celikin,Mert Celikin,Federico Rosei,Federico Rosei,Riad Nechache +7 more
TL;DR: In this article, a power conversion efficiency of 4.20% under 1'sun illumination from Bi-Mn-O composite thin films with mixed BiMnO3 and biMn2O5 crystal phases was reported, where the photocurrent density and photovoltage mainly develop across grain boundaries and interfaces rather than within the grains.
Journal ArticleDOI
Photovoltaic effect in multiphase Bi-Mn-O thin films.
TL;DR: It is found that the Bi/Mn ratio in the film affects the magnitude of the photo induced voltage and photocurrent and therefore the photovoltaic conversion efficiency, and a higher Bi/mn ratio (towards unity) in theFilm increases the power conversion efficiency.
Journal ArticleDOI
Photovoltaic Properties of Multiferroic BiFeO3/BiCrO3 Heterostructures
Joyprokash Chakrabartty,Riad Nechache,Riad Nechache,Shun Li,Mischa Nicklaus,Andreaus Ruediger,Federico Rosei,Federico Rosei +7 more
TL;DR: In this paper, the authors reported a power conversion efficiency of 0.01% in multistacking of BiFeO3/BiCrO3 bilayer thin films used as active layers in a photovoltaic (PV) device, which was epitaxially deposited by pulse laser deposition onto (100) oriented CaRuO3-coated LaAlO3 substrates and subsequently illuminated with 1 sun (AM 1.5).
Journal ArticleDOI
Enhanced photovoltaic properties in bilayer BiFeO3/Bi-Mn-O thin films.
Joyprokash Chakrabartty,Riad Nechache,Riad Nechache,Catalin Harnagea,Shun Li,Federico Rosei,Federico Rosei,Federico Rosei +7 more
TL;DR: It is demonstrated that the photocurrent density and photovoltage are tunable by changing the polarization direction in the BFO/BMO bilayer, as confirmed by the macroscopic polarization-voltage (P-V) hysteresis loop.
