Ricoh and Ricoh Japan announced on March 15 that they will begin testing perovskite solar cells together with the Tokyo Metropolitan Government and Tokyo Housing Corporation (JKK Tokyo). IoT sensors equipped with perovskite solar cells will be installed at the Tokyo Metropolitan Government Building and at Kosher Heim Mukaihara, a housing facility for the elderly with JKK services. The expected verification period is one year.

Perovskite solar cells are lightweight and can generate electricity even in poorly lit areas or when installed vertically. However, there are still durability issues outdoors and indoors with low illumination. This time, an IoT sensor equipped with perovskite solar cells developed by Ricoh will be installed and operated, and the power generation efficiency, durability, communication status, etc. of the perovskite solar cells will be determined. bright.

IoT sensors measure temperature, humidity, brightness, and CO2 concentration, and can transmit data via LoRa wireless networks. The Tokyo Metropolitan Government Building has installed 5 IoT sensors and monitors in the observation room on the 45th floor. Based on the temperature, humidity and CO2 concentration obtained, data is displayed on the monitor to help management management of ventilation and air conditioning systems and better understanding of crowded conditions It will be verified as a system that leads to maintenance management and a sense of security for visitors. It was installed on March 10 and opened to the public on the 20th.
At Kosher Heim Mukaihara, IoT sensors are installed in five locations, including hallways, common areas and private rooms, and are used as guides to manage temperature, humidity and ventilation in the facility to help ensure the safety and security of residents. It is also envisioned that a light sensor would be used to confirm vehicle safety based on the presence or absence of light. Installation is scheduled for the end of March.
Ricoh has the track record of selling the world's first solid-state dye-sensitized solar cells, which can generate electricity even under low-intensity indoor lighting, by applying organic photoreceptor technology mechanics are developed through the development of multifunctional devices. From 2023, the company is working on developing perovskite solar cells, including next-generation solar cell demonstration experiments at 7-Eleven stores and demonstration experiments with Ota Ward. Through this demonstration, we aim to commercialize perovskite solar cells as soon as possible.
