Researchers are increasingly turning their efforts on perovskite solar cells, one of the most promising developments for photovoltaic energy. Despite their novelty, the efficiency of perovskite solar cells is already approaching that of ubiquitous silicon solar cells.The biggest roadblock to achieving this potential is the long-term stability of the perovskite materials.

The research was carried out by the group of Dr. Michael Saliba at AMI. This time, the problem of the highly volatile and heat-sensitive methylammonium (MA) molecule was addressed. The most efficient perovskite solar cells containunstable MA, mainly because it provides high-performance values. By introducinginorganic elements, the researchers have shown it is possible to avoid unstable MA while maintaining similar highperformances. This allows for more stable solar cells, which is a key step towards eventual commercial use.

“These new perovskites can also harvest more sunlight, meaning they are more efficient and therefore more profitable,” explains Saliba. “In addition, these new materials are compatible with flexible substrates, making them useful for a wide variety of applications.”

“Essentially, this sets perovskites on the path of becoming a profitable, long-term solution for a sustainable energy future. With small additional improvements, perovskite solar cells can become a commercial reality within a short time.”

The results are published in the October 11 issue ofScience.

This study was carried out in collaboration with the Hagfeldt group at the Laboratory of Photomolecular Science (LSPM) at the Federal Institute of Technology in Lausanne.

In this video I’m going to show you 3 ways you can reduce penile plaque, fast.

And why is this important?

Because penile plaque builds up in the blood vessels in and near your penis, interrupting blood flow.

Less blood flow = worse erections.

That’s the bad news. The good news is you can do something about it.

If you are interested in installing Solar Panels for your Home or RV then you need to know what the salesperson won’t tell you as well as what the meaning is for what they do tell you.

When I asked Solar Sam, real name Ralph George, what is missing from the solar system salespersons spiel he told me that they nearly always forget to tell you about maintenance or shading and how that impacts the efficiency of your solar panel system.

Solar Sam then told me that even a small amount of shading in one corner of your whole solar panel array can reduce the output by as much as 60% which costs you money or storage depending on whether you have installed a grid connected system or a fully standalone solar system.

“The reason for this is the way the panels are connected together and it is possible to connect them in such a way that these impacts are minimised but salespeople generally don’t even mention the problem let alone the solution” said Sam.

OK, that covers shading but what about the maintenance? “All solar panels either on your home or your RV collect dust, dirt and bird droppings. These all have the effect of reducing the efficiency of your panels and reduce the power output” said Solar Sam. “It can be as bad or even worse than shading so annual cleaning should be the minimum that’s done.”

According to Sam this lack of information is an unfortunate side effect of the salesperson’s desire to make a sale without making sure that you, the buyer and ultimate beneficiary of those solar panels, fully understand the limitations as well as the benefits of installing solar panels for a grid connect system or a full off-grid solar system.

Since I am also in the market for an off-grid system for my motorhome I found this discussion with Solar Sam to be of major interest and he has helped me to make good decisions about what type of solar panel kit to buy. He also pointed me to an excellent source of good quality and affordable panels, batteries, controllers, inverters, cabling and plugs if I chose to buy the components individually rather than one of their excellent kits.

Guangzhou Sinotech Laser Machinery Co. Ltd is celebrating ten years of producing quality laser machinery product

It is slightly ten years since Guangzhou Sinotech Laser Machinery Co. Ltd started producing laser machinery products in China. The cover has grown to become the leading researcher, developer and producer of laser machinery product in China and world over. Since its inception in 2006, Guangzhou Sinotech Laser Machinery Co has been producing high quality laser marking machine, laser cutting machine, laser cutting bed, small laser machine, laser engraving machine, metal laser cutting machine, laser welding machine among other laser machinery products. The company has obtained CE, SGS, FCC and RoHS Certificate for its products, something that the company representative says is a proof of the high quality that they have been maintaining over the years.

Guangzhou Sinotech Laser Machinery Co has sold its laser cutting machine, laser engraving machine and other laser machinery in more than thirty provinces across China. They have also exported the laser machines to a number of countries including Russia, United States, Middle East countries, South East Asia, Australia and many others. The company according to the spokesperson works regularly with large global importers and retailers. Its clientele range from domestic and overseas learning institutions, businesses, home and hobby users. Retailers who were congratulating the company for its quality products, timely delivery and competitive offers say that they will continue partnering with the company to ensure that its products get to the customers all over the country and across the globe.

Within the last ten years the company has made great strides including the research and production of the first Sinotech laser cutting machine in 2008, development of a new fiber laser cutting machine factory, and brand becoming more popular. In 2017 the annual sales reached 8,000,000 USD. The company spokesperson says that the company is looking forward to more strides and promises to continue producing quality bending machines, laser machine accessories among other products.
