Hosiden is now joining the Perovskite solar cell business, the next-generation of solar cell technologies.
Silicon-based solar cells, which are the current mainstream of the solar cell industry, depend on a high-temperature process for silicon wafer component manufacture, which results in high power consumption during the production process. Also the use of minerals cause a relatively high production cost.
Perovskite solar cells, produced under a low-temperature process with less power consumption, use organic materials which are also expected to reduce production costs.
For production, touch panel production lines owned by the affiliated company, Hosiden FD (Shiga Prefecture) can be effectively utilized as an existing facility, because of its high affinity with the production of Perovskite solar cells. In the future, Hosiden is expecting to start mass production of flexible solar cells by utilizing the production lines of the film-based touch panels that Hosiden owns in Korea and Vietnam.
The Perovskite solar cells have a higher conversion efficiency than conventional organic solar cells, and according to reports from many research institutes, the efficiency is even better than that of silicon-base cells. Light-weight and flexible features are most suitable for mobile and IoT devices, and further expansion of applications is anticipated.
Sample introduction begins in FY2021, with mass production machinery being introduced in 2022, and mass production starting from 2023.
[Product Name]
Perovskite solar cells
・Strong absorption at visible light wavelengths, the cells maintain high power generation efficiency not only at high illumination levels (sunny outdoors) but also in
mo derate (cloudy outdoors) or low (indoors with light ON) illumination. The photoelectric conversion efficiency is higher compared to silicon solar cells.
・The thin film design allows greater power generation per unit weight. Using ultra-thin glass or plastic films as a base material realizes a light-weight and flexible
solar cell without compromises, leading to an extensive range of applications.
・The low temperature coating process and the layer composition of the resulting extremely thin film at the nano-level, contributes to lower materials cost. Also,
the resulting light-weight product allows reductions of installation and transportation costs.
・As production is possible using a lower temperature process, the power consumption during production process can be greatly reduced.
The principal organic materials used in the cell construction reduce the consumption of mineral resources, so promoting a decrease of environmental impact.
・IoT devices, sensors
