Researchers develop efficient solar cell technology by imitating plants' photosynthesis procedure
By causing a suitable electron flow procedure called vectorial transfer, South Korean researchers had the ability to create a solar cell production technique that can produce cells with as much as 60 percent more electron transfer efficiency than traditional cells. The brand-new technique allows photovoltaic cells to manage electron flow in one desired instructions to minimize the loss of electrons throughout power generation.

Enhancing the performance of solar cells with 'graphene armor'
A group of scientists, connected with UNIST has actually thought of a novel electrode that might substantially boost the security of perovskite solar cells (PSCs), one of the most promising prospect for the next generation solar cells because of their low cost and high power conversion effectiveness. This is due to the fact that putting a protection layer in between the metal-based electrode as well as the perovskite movie can stop metal-induced deterioration and that graphene, thus a layer, can effectively subdue the diffusion of steels and also halide ions.

Inexpensive as well as reliable method to change solar cells from nontransparent to clear
Scientists in Korea have actually discovered a economical and also reliable method to change solar cells from nontransparent to clear. Existing clear solar cells have a tendency to have a red shade as well as reduced performance, yet by punching openings that are around 100? m in size (equivalent in dimension to a human hair) on crystalline silicon wafers, it permits light via without tinting. The holes are after that tactically spaced, so the human eye is not able to "see" the pattern. The job shows up December 11 in the journal Joule.
