A solar-powered microwave is a low-powered microwave that conserves your solar battery when you're using solar panels to gather off-grid electricity. It can be useful for those living in mobile homes or campers, or for those working outside of the city and beyond the reach of power lines.
Eng. 161 012068 Abstract. In the present study, the potential of microwave irradiation as an innovative energy applications of possible commercial interest. Ceramic materials have been extensively studied and used due to several advantages they exhibit. Sintering ceramics using microwave radiation,
A microwave technology invented at Macquarie University will improve the manufacture of solar cells and make them easier to recycle. During the fabrication of solar panels, silicon goes through several high-temperature processes known as annealing. Currently the cells are cooked in an oven.
In addition, microwaves can be focused and used to selectively heat sections of the solar panel, making them good for annealing newer solar panels, which employ heterojunction technology, where crystalline and amorphous silicon are interwoven.
One of the co-authors of the annealing paper, Associate Professor Shujuan Huang, leads a group looking at microwave annealing in perovskite solar cells. Perovskites are a group of crystalline minerals with semiconductor properties that may, in future, be used for solar cells because they are flexible, lightweight and cheap to produce.
Currently the cells are cooked in an oven. But in a paper published in the US Journal Applied Physics Letters, a team led by senior lecturer Dr Binesh Puthen Veettil of the School of Engineering has shown that heating using microwave radiation is nearly as efficient. Plus, it saves considerable time and energy and has other advantages.
