Researchers Develop Self-Healing Solar Cells

self-healing solar cell

A group of researchers at the North Carolina State University (NCSU) have recently successfully developed solar cells that are able to heal themselves. More specifically, the scientists have successfully been able to solve the problem of dye-sensitized solar cells (DSSC), namely that the dyes used to create energy in these cells would eventually be destroyed by UV radiation.

DSSC cells contain a water-based gel core, electrodes, and inexpensive, light-sensitive, organic dye molecules that capture light and generate electric current. The original cells were created by mimicking the photosynthesis process that occurs in the leaves of plants. In trying to solve the problem of the dyes eventually becoming ineffective due to exposure to UV rays, the NCSU scientists again looked to plants for inspiration. The solar cells they developed contain a network of vascular channels that are very similar to the veins in a leaf, which are used to maintain water and nutrient levels throughout the leaf. The researches found that the needed dyes could be effectively delivered and replenished via this network. The dye that had been rendered ineffective by UV radiation can also be removed through this network.

A New Water Heater Cuts Energy Use by Nearly Half

heater

The firm ISI Technology of South Carolina will soon begin producing a smart water heater, which is designed to cut energy use by 40% over conventional water heaters. They have recently successfully met their funding goal of $125,000 through Kickstarter to begin the production. The Heatworks MODEL 1 compact water heater will measure 12.5 inches by 6.5 inches, meaning that it will fit in most spaces. The water heater will also have Wi-Fi connectivity, so that temperature, power levels and duration can all be monitored and controlled remotely.

fluxHome Combines Passive and Active Principles for Net Zero Energy Use

fluxHome-Foundations

One of four teams that are representing California in the 2013 Solar Decathlon, Team USC (from the University of Southern California) will be submitting its fluxHome, a net zero prototype, as an entry in the competition to be held in October 2013 in Irvine, California.

fluxHome reimagines the suburban tract home in an energy efficient and affordable combination of smart home technologies with readily available and customizable components that can serve as a single family residence for up to four people or be adapted to other lifestyle scenarios.
