Recently, the Graduate School of Okinawa University of Science and Technology in Japan has developed a new type of all-inorganic perovskite solar cell, which solves three key problems plaguing solar cell technology: efficiency, stability and cost
.
It is understood that electronic devices with solar cells can directly convert light energy into electrical energy for use
.
So far, most solar cells have been made of silicon, mainly to take advantage of the substance's easy absorption of light, but silicon panels are expensive to produce, so cost-effectiveness has always been an issue
.
Scientists have been working on an alternative material
made from perovskite structures.
Perovskite is a mineral found on Earth, composed of calcium, titanium and oxygen arranged by specific molecules, and scientists study materials with the same crystal structure, that is, perovskite structural materials
.
Perovskite materials are very practical as a light-collecting active layer for solar cells because they absorb light efficiently and, more importantly, are much cheaper than silicon
.
But this material is not perfect, perovskite structural materials are usually very unstable, unstable when the temperature is too high, which hinders its commercialization
.
The Institute of Energy Materials and Surface Science, Graduate School of Okinawa University of Science and Technology, led by Professor Qi Yaping, discovered a new perovskite material that is stable, efficient, and relatively low to produce, and will be more widely used in solar cells in the future
.
But there are still many challenges to overcome
before perovskite solar cells become commercially viable like silicon solar cells.
Qi and his colleagues will continue to study the efficiency and durability of these new batteries, and are manufacturing them on a commercial scale
.
Given the rapid pace of development of the technology since the first perovskite solar cells were reported in 2009, the future of new batteries can be said to be very bright
