Indoor Light Harvesting Perovskite Photovoltaics Cell for Self-powered Smart Electronic Devices Application
(REF: S-0254) |
| Matched I&T Wish |
|
| Trial Project |
|
| Solution Feature |
- HPS fabricated a scalable perovskite solar cell by using printable device procedure; the use of indoor photovoltaic cells to power billions of wireless devices for a future Internet of Things (IoT) nodes is becoming possible.
- The prototype perovskite solar cells (active area 1.5 x 1.5 cm) achieved power conversion efficiency over 25% within 120 μΑ / 980 mV generated 0.15 mW under 1000 lux indoor light (2700 K fluorescent light).
- By designing perovskite material with suitable bandgap and suppressed trap defects can attain a higher efficiency with increased open circuit voltage and minimal short-circuit current loss.
- Indoor photovoltaic cells are integrated into large-scale modules with well sealing technology that can demonstrate long-term stability.
- The indoor light harvesting by perovskite photovoltaics cell can offer consecutive power for low-power consumption smart electronics e.g. temperature and humidity sensors under off-grid environment.
|
| Trial Application and Expected Outcome |
- Optimized scalable perovskite photovoltaics cells, investigating different device parameters and property test (including module efficiency, power density, durability and etc.)
- The indoor light harvesting integrated devices with various smart electronics or wireless sensors under off-grid environment will be conducted.
- On-site installation of indoor light harvesting integrated devices and long-term on-site performance measurement, including indoor power conversion efficiency, durability and energy saving potential.
- Guideline of the application of indoor light harvesting integrated devices in self-powered sensors/IoT devices applications.
