Journal ArticleDOI
Panchromatic engineering for dye-sensitized solar cells
TL;DR: In this article, a dye-sensitized mesoscopic solar cell has been investigated as a promising photovoltaic cell and strategies for achieving panchromatic response in DSCs are discussed, where the primary step is performed by a sensitizer anchored to the surface of a wide band gap semiconductor.
Journal ArticleDOI
Methodologies toward Highly Efficient Perovskite Solar Cells.
TL;DR: Understanding chemical species in precursor solution, crystal growth kinetics, light-matter interaction, and controlling defects is expected to give important insights into not only reproducible production of high PCE over 20% but also further enhancement of the PCE of PCSs.
Journal ArticleDOI
Vacuum-Assisted Thermal Annealing of CH3NH3PbI3 for Highly Stable and Efficient Perovskite Solar Cells
Fengxian Xie,Di Zhang,Huimin Su,Xingang Ren,Kam Sing Wong,Michael Grätzel,Wallace C. H. Choy +6 more
TL;DR: Vacuum-assisted thermal annealing is demonstrated as an effective means for controlling the composition and morphology of the CH(3)NH( 3)PbI(3), which significantly improves the device stability and reproducibility with a standard deviation of only 0.92% in PCE as well as strongly reducing the photocurrent hysteresis.
Journal ArticleDOI
Demonstrating Electron Transfer and Nanotechnology: A Natural Dye-Sensitized Nanocrystalline Energy Converter
Greg P. Smestad,Michael Grätzel +1 more
TL;DR: In this paper, a unique solar cell fabrication procedure has been developed using natural anthocyanin dyes extracted from berries, which can be reproduced with a minimum amount of resources in order to provide an interdisciplinary approach for lower-division undergraduate students learning the basic principles of biological extraction, physical chemistry, and spectroscopy as well as environmental science and electron transfer.
Journal ArticleDOI
Gallium arsenide p-i-n radial structures for photovoltaic applications
TL;DR: In this paper, the currentvoltage characteristics of single nanowires were measured in the dark and under various illumination conditions including 1.5 AM, and the total efficiency was 4.5%.
