Precision spray coating could enable solar cells with better performance and stability

Although perovskites are a promising alternative to the silicon used to make most of today’s solar cells, new manufacturing processes are needed to make them practical for commercial production. To help fill this gap, researchers have developed a new precision spray-coating method that enables more complex perovskite solar cell designs and could be scaled up for mass production.

Next gen solar cells perform better when there’s a camera around

(ARC Centre of Excellence in Exciton Science) A literal “trick of the light” can detect imperfections in next-gen solar cells, boosting their efficiency to match that of existing silicon-based versions, researchers have found.

Perovskite Solar Cells … Toyota Driving Off A Hybrid Cliff … The Boring Company’s 1st Vegas Tunnel — #CleanTechnica Top 20

: Tesla Model X inside The Boring Company's test tunnel underneath the SpaceX offices (Image: The Boring Company)The most popular CleanTechnica stories last week involved perovskite solar cell research and projections (a hot topic for the past few — or several — years), Toyota’s continued focus on hybrids (considered by many to be a death knell for the hybrid leader and 100% electric laggard), and The Boring Company’s first of two Las Vegas tunnels

Scientists develop safer lead-based perovskite solar cell

(Northern Illinois University) Researchers at Northern Illinois University and the US Department of Energy’s (DOE) National Renewable Energy Laboratory are reporting today (Feb. 19) in the journal Nature on a potential breakthrough in the development of hybrid perovskite solar cells. The scientists developed a technique to sequester the lead used to make perovskite solar cells and minimize potential toxic leakage.

New technique lets researchers map strain in next-gen solar cells

Researchers have developed a way to map strain in lead halide perovskite solar cells without harming them. Their approach can image the grain structure of a perovskite solar cell, showing that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell. Crystal misorientation creates small-scale defects in the grain structure, which interrupt the transport of electrons within the solar cell and lead to heat loss.
