Journal ArticleDOI
Maximizing Short Circuit Current Density and Open Circuit Voltage in Oxygen Vacancy-Controlled Bi1-xCaxFe1-yTiyO3-δ Thin-Film Solar Cells.
TL;DR: This work demonstrates oxygen vacancies (VO), present within the lattice and at grain boundary (GB), can explicitly be controlled to achieve high JSC and VOC simultaneously and demonstrates the efficiency ~ 0.22 % can be achieved in solid state BFO solar cells under AM 1.5 one Sun illumination.
Journal ArticleDOI
Photoconductivity induced by nanoparticle segregated grain-boundary in spark plasma sintered BiFeO3
TL;DR: In this article, photo-response of nanoparticle-segregated grain boundary (BFO-AP) and clean grain boundary(BFO -AA) samples was investigated on spark plasma sintered BiFeO3 samples with two contrasting morphologies.
Journal ArticleDOI
Oxygen vacancy induced photoconductivity enhancement in Bi 1-x Ca x FeO 3-δ nanoparticle ceramics: A combined experimental and theoretical study
TL;DR: Based on experimental and density functional studies, the authors showed that tailoring of oxygen vacancies (OV) leads to large scale enhancement of photoconductivity in BiFeO3 (BFO).
Journal ArticleDOI
Enhanced Charge Transport and Excited-State Charge-Transfer Dynamics in a Colloidal Mixture of CdTe and Graphene Quantum Dots
Malay Krishna Mahato,Chinju Govind,Venugopal Karunakaran,Subhajit Nandy,Chandran Sudakar,Edamana Prasad +5 more
TL;DR: Semiconductor quantum dot composites are promising materials for photovoltaics and photocatalysis because of efficient charge extraction and transport property of graphene as mentioned in this paper. But their performance is limited.
Journal ArticleDOI
Structural, electrical, optical and thermoelectric properties of e-beam evaporated Bi-rich Bi2Te3 thin films
TL;DR: In this article, Bi-rich Bi2Te3 (Bi-BT-AD) thin films are prepared at 300 K using e-beam evaporation technique and X-ray diffraction measurements reveal the presence of Bi phase together with crystalline Bi 2Te3.
