Solar Trend in 2020.


After their introduction in the 1960s, Solar innovations have evolved a lot. Although solar photostatic (PV) were once seen as a thing of the future, today the industry has been poised for great growth in technological breakthroughs. A number of new innovations in solar photostatic technology will also contribute to the success of the industry. Researchers have sought ways to improve solar cell efficiency and cost efficiency-the lifeblood of solar photo-voltaic systems. Hundreds, or thousands, of solar cells, which transform radiant sunlight individually into electrical currents, consist of a solar PV array.

The typical solar cell performs about 15%, so that almost 85% of the sun's light entering them does not become electric. As such, scientists have been actively exploring new techniques to improve the capture and conversion of light. Nano-particles with light sensitivity. A new light-sensitive type of nano-part called colloidal quantum points was recently unveiled by a group of scientists at University of Toronto. Some hope it will provide less costly and more versatile material for solar cells.

In particular, the new materials use semiconductors of n-type and p-type–but those which can work outdoors. This is a remarkable development because previous designs could not work on the outside and thus not on the solar market. Researchers of the University of Toronto find that n-type materials bind to oxygen-new aquatic colloidal points do not bind to the air and can thus preserve their external stability. This increases the absorption of radiant light. Sun-conversion panels that use this new technology have been found to be up to 8% more effective.

Researchers at imperial college in London believe that they have found a new material-gallium arsenide-that could almost three times more efficient than existing on the market for solar photo-voltaic systems. The solar cells are called "triple junction plates" because they can be chemically altered to maximize the absorption of sunlight. The model is equipped with a sensor-driven window blind to track sunlight with "light pipes" which guide the system into light.

Advanced Technology
Scientists will also concentrate on finding new ways of store solar photo-voltaic energy. At present electricity is mostly a' use or lose it' tool, whereby electricity will be used or lost as soon as produced by the solar photo-voltaic system (or any form of fuel source) on the grid. As the sun does not shine twenty four hours daily, this means that the majority of solar photo-voltaic systems meet the electricity requirements for only a fraction of the day–resulting in the loss of much power if not used.

There are a series of energy storage batteries on the market, but even the most advanced ones are quite inefficient, are also expensive and have a rather short shelf life and are not the most appealing options for utilities and consumers. Therefore, scientists are exploring various ways of stocking this power to be used on demand. Novatec Soler recently commissioned a promising power storage approach with a molten salt storage technology for solar photo-voltaic systems. This process uses inorganic salts to transfer solar photo-voltaic energy to thermal solar energy with heat transmission fluids rather than oils.

The effect is that solar plants are able to operate at temperatures above 500 ° C, resulting in a significantly higher energy output. That would significantly decrease the costs of storing solar and power suppliers could eventually use solar power plants as base load power units instead of meeting peak demand in the early hours of daylight. Built-in battery solar panel. Researchers of the Ohio State University recently announced in a project funded by the U.S. Department of Energy that the production of batteries is 20% more efficient and 25% cheaper than anything on the market today.

Advance Manufacturing Technology
The manufacturing process is another field which has restricted the use of solar photo-voltaic technologies compared to conventional fuels. Scientists will also focus on ways of improving the efficiency of the production of solar components. While over ninety percent of the solar panels on the market today are made up of silicon semiconductors, which are a key ingredient for converting the sunlight into electricity, many think that the next generation of solar panels will be manufactured from a thin film technology which uses narrow coverings of cadmium telephuride in solar cells.

One of the biggest obstacles for cadmium telluride thin film cells is that during the production process, the use of cadmium chloride is very unstable. Researchers have developed a new, safe and seemingly low cost way to overcome this challenge using magnesium chloride as a substitute for cadmium chloride. The plentiful supply of magnesium chchloride, seawater, which makes both the products very small and non-toxic, is retrieved. The production process is replaced with this material, which promises an increase of 2% to 15% in the efficiency of these solar cells.

New Application Scope
If most people think of solar photo-voltaic systems they think of them on top of roofs. But researchers are exploring a number of innovative solar applications which might promise the industry to change. Scientists are investigating ways to line roads with solar panels to then use large quantities of electricity in the grid. This would help to remove a significant obstacle to the solar industry, which opponents say is threatening to take over too much ground. In the Netherlands, solar roads have already appeared.

The establishment of solar plants on the water is another way of addressing land-use issues associated with large-scale solar, with water covering more than 70 percent of the Earth's surface area. This technology is experimented by certain researchers, including a French company called Ciel et Terre. The company is also piloting projects, including projects in India and California in the US in French, Japan and England, as well as other places in the world.

Scientists resurrect a technique tested first more than 40 years ago in which space-based satellites catch the sun and turn it back into a microwave energy. This kind of technology promises to capture significantly more sunlight (almost 90%), since satellites can be placed around the clock to optimize light capture. In these technologies India, China and Japan are currently investing heavily.
