Metal free sensitizer and catalyst for dye sensitized solar cells
TLDR
In this paper, a metal free sensitizer and electrocatalyst related to dye-sensitized solar cells (DSSCs) are reviewed for their merits and the current state-of-the-art sensitizers as well as carbon based materials for its chemistry and photovoltaic characterization are discussed.Abstract:
The carbon neutral process for energy conversion is of utmost importance, in this context photovoltaics, especially dye sensitized solar cells (DSSCs) are a viable alternative. Few terawatts of carbon free renewable energy can be produced by DSSCs. However the judicious use of platinum group free metals may further enhance the limit of energy production by making it further cost effective. In this context a metal free sensitizer and electrocatalyst related to DSSCs are reviewed for their merits. The current state-of-the-art sensitizer as well as carbon based materials for its chemistry and photovoltaic characterization are discussed. The present article combines recent progress and its emerging behavior from our laboratories and from other groups working on this perennial topic.read more

Perovskite as Light Harvester: A Game Changer in Photovoltaics
TL;DR: Perovskites are of great interest in photovoltaic devices due to their panchromatic light absorption and ambipolar behavior and it will not be unrealistic to speculate that one day perovskite-based solar cells can match the capability and capacity of existing technologies.

Pt-free counter electrode for dye-sensitized solar cells with high efficiency
TL;DR: This Progress Report focuses on the design of novel Pt-free CE catalytic materials, including design ideas, fabrication approaches, characterization techniques, first-principle density functional theory (DFT) calculations, ab-initio Car-Parrinello molecular dynamics (CPMD) simulations, and stability evaluations, that serve as practical alternatives to conventional noble metal Pt electrodes.

TL;DR: It is shown that graphene grows in a self-limiting way on copper films as large-area sheets (one square centimeter) from methane through a chemical vapor deposition process, and graphene film transfer processes to arbitrary substrates showed electron mobilities as high as 4050 square centimeters per volt per second at room temperature.

TL;DR: The direct synthesis of large-scale graphene films using chemical vapour deposition on thin nickel layers is reported, and two different methods of patterning the films and transferring them to arbitrary substrates are presented, implying that the quality of graphene grown by chemical vapours is as high as mechanically cleaved graphene.
