Macnica (Headquarters: Yokohama City, Kanagawa Prefecture, President: Kazumasa Hara, hereinafter referred to as "Macnica"), a total service and solution provider in semiconductors, networks, cybersecurity, and AI/IoT, has announced that EneCoat Technologies Co.,Ltd. (Headquarters: Kyoto City, Kyoto Prefecture, Representative Board Director: Naoya Kato, hereinafter referred to as "Enecort") and We are pleased to announce that we have succeeded in the joint development of an IoT CO2 sensor terminal using perovskite solar cells, which are said to be the favorite of next-generation solar cells.

Perovskite solar cells (PSCs) are high-performance solar cells that combine the properties of thin-film solar cells with power generation performance comparable to crystalline silicon solar cells (the highest conversion efficiency recorded for a cell size as of December 2021 was 25.7%), and are considered the leading candidate for next-generation solar cells. They are thin, light, and bendable, and can even be made semi-transparent by devising the material composition, so they are expected to be used in fields where conventional crystalline silicon solar cells cannot be installed. In addition, it is said that if large-area coating technology is established, significant cost reductions will be possible.
Enecoat has developed perovskite solar cells that are optimized for IoT devices in terms of power consumption and shape, and Macnica has utilized the benefits of this next-generation solar cell to develop a device that can operate a CO2 sensor even in indoor environments and transmit information wirelessly.
It has been said that operating a CO2 sensor and transmitting data stably without an external power supply in indoor lighting environments is difficult due to the balance between the power generation efficiency of the solar cell and the power consumption of the sensor itself. However, thanks to Enecoat's perovskite solar cells, which have sufficient power generation capacity even under low lighting conditions, and Macnica 's low power consumption design technology, which utilizes its extensive semiconductor knowledge, we have succeeded in developing a next-generation IoT CO2 sensor terminal that can be powered solely by solar cells.

Macnica 's superordinate concept is `` Our Group's Purpose'. ^{* 1} We are conducting business activities as a global service and solutions company, aiming to solve social issues and global environmental issues, and create future value. Based on the backcasting concept from the goal of achieving carbon neutrality in 2050, we will utilize low power consumption, battery-less, renewable energy, and IoT technologies to realize a decarbonized society and minimize waste generation. As an initiative to promote the concept of circular economy, Macnica will actively work on developing renewable energy IoT products that are battery-less and can continue to operate without the need to replace batteries.
The jointly developed IoT CO2 sensor terminal will begin shipping prototypes to specific customers in April as a PoC (Proof of Concept) product, and will be used to monitor CO2 as a countermeasure against COVID-19. We will continue to install and evaluate the system for specific applications such as measuring certain indoor environments and measuring CO2 concentration at plant factories. This product is also compatible with Macnica 's air quality solution "AiryQonnect". ^{* 2}” is scheduled to be included in the product terminal lineup in the future.
