Matched I&T Solution Indoor Light Harvesting Perovskite Photovoltaics Cell for Self-powered Smart Electronic Devices Application
(REF: S-0254)
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.
