New solar windows are expected to replace current rooftop solar panels: more stable and higher

Australian scientists published a paper in Nano Energy magazine that translucent solar cells that can be embedded in window glass may change architecture, urban planning and power generation.

Researchers led by the ARC Excitonic Science Center and Professor Jacek Jasieniak of Monash University have successfully manufactured the next generation of perovskite solar cells, which can generate electricity while passing light.

They are currently studying how to combine this new technology with the products of Australian glass manufacturer Viridian Glass.

This technology will transform windows into active generators, which may bring revolutionary changes to architectural design.

The researchers say that the electricity generated by a two-square-meter solar window is equivalent to a standard rooftop solar panel.

It is reported that the idea of ​​translucent solar cells is not new, but previous designs have failed because they are very expensive, unstable or inefficient.

The stability of commonly used solar cell modules is very low, because it will form a useless water-based coating over time.

Professor Jasieniak and his research team used an organic semiconductor that can be made into a polymer to replace a commonly used solar cell module, which has produced amazing results.

Jacek said: "The conversion efficiency of rooftop solar energy is between 15% and 20%." "The conversion efficiency of this translucent cell is 17%, but it can still transmit more than 10% of the incident light, so they are just in this area. It has always been a dream for people to have windows that generate electricity, and now it seems that this is possible. "

The research team is currently expanding the manufacturing process, and scientist Dr. Anthony Chesman said: "We will seek to develop a large-scale glass manufacturing process that can be easily transferred to industry so that manufacturers can easily adopt this Technology. "

Professor Jasieniak explained: "The transparency of solar cells can be increased or decreased. The more transparent they are, the less electricity they generate, which becomes an issue for architects to consider."

He also said that solar windows, which are the same level as current glass commercial windows, will generate about 140 watts of electricity per square meter.

It is understood that large windows in high-rise buildings are expensive to make, but the extra cost of incorporating such translucent solar cells into them is negligible.

"But even with additional costs, this building can use electricity for free," said Professor Jasieniak.

"These solar cells mean that the way we think about buildings and their functions will change dramatically. So far, the window design of every building is basically passive. Now they will actively generate electricity."

He also said: "Planners and designers may even have to reconsider how to arrange buildings on the site to optimize the way the walls absorb sunlight."

Researcher Dr. Jae Choul Yu said: "Our next project is to connect devices in series and use perovskite solar cells as the bottom layer and organic solar cells as the top layer."

As for when the first commercial translucent solar cell will be marketed, Professor Jasieniak said: "It will depend on the successful promotion of this technology, but our goal is to achieve this within 10 years."

The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.

System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.

Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.

The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.

Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.

Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.

High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.

Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.

About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
