In recent years, the cost of solar photovoltaics has dropped significantly. However, compared with the cost of conventional energy generation, it is still a long time before solar energy is really competitive.
How can solar energy costs continue to fall? Paul Dastoor, an expert from the University of Newcastle, Australia, and his team are experimenting with printed solar panels to print electronic inks on solid PET plastics. film.
This solar panel has a thickness of one tenth of a millimeter and can generate electricity under astigmatism and dim light conditions. Therefore, it can be installed anywhere as needed without having to consider the inclination of relative sunlight.
At present, researchers have printed 100 square meters of new solar panels for testing to further improve their performance and durability. It is estimated that the cost of this photovoltaic panel after quantification is less than 8 US$/square meter, far lower than the cost of solar tile introduced by Tesla (235 US$/m2).
