A few days ago, according to the science and technology media Electronics 360, scientists at the University of Melbourne, Australia, developed a solar cell black technology: The research team used a special printer to print solar cells directly on A3 paper-sized flexible, translucent plastic sheets!

The team of scientists uses a solar cell called nematic liquid crystals that are not only easy to produce but also improve the performance of solar cells. Compared with the current solar market mainstream crystalline silicon solar panels and thin film solar panels, this printed solar cell wins at a low price and can be freely customized: the price per meter is less than 10 US dollars, and is not limited to size , can be tailored according to actual needs.
At present, the power efficiency of this printing solar cell is between 8% and 9.3%. Also, the team is studying the use of hybrid materials as batteries, and intends to increase power generation efficiency to 18%. Once a breakthrough is achieved, the power generation efficiency of printed solar power will compete with current thin-film solar cells.
Needless to say, this type of printed solar cell is a major breakthrough in the field of solar energy and can greatly expand solar energy application scenarios such as installing solar panels on windows, clothes, mobile phones, automobiles, and so on.
The research results are still in the testing phase. However, the research team hopes to seek corporate cooperation or venture capital investment to accelerate the pace of research and development and bring it to market quickly.
A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
