Li containing p-on-n and n-on-p Si cell degradation by bombardment noting carrier removal damage, annealing and radiation damage resistance
The U.S. Department of Energy’s (DOE’s) efforts have greatly advanced the state of the art of hydrogen and fuel cell technologies —making significant progress toward overcoming many of the key challenges to widespread commercialization. DOE has also made major advances by demonstrating and validating the technologies under real-world conditions, supporting early markets through Recovery Act deployments, and leveraging domestic and international partnerships to advance the pace of commercialization.

All-organic dyes have shown promising potential as an effective sensitizer in dye-sensitized solar cells (DSSCs). The design concept of all-organic dyes to improve light-to-electric-energy conversion is discussed based on the absorption, electron injection, dye regeneration, and recombination. How the electron-donor–acceptor-type framework can provide better light harvesting through bandgap-tuning and why proper arrangement of acceptor/anchoring groups within a conjugated dye frame is important in suppressing improper charge recombination in DSSCs are discussed. Separating the electron acceptor from the anchoring unit in the donor–acceptor-type organic dye would be a promising strategy to reduce recombination and improve photocurrent generation.
