New Tool for Perovskite Solar Cell Development: GaAs-Equipped Reference Cell

Calibration of reference solar cells using the solar simulator method. Reference cells with GaAs that have similar spectral sensitivity characteristics and high stability.

GaAs-type (III-V compound semiconductor) cells have spectral sensitivity characteristics that are much more similar to perovskite-type cells compared to conventional Si-type cells, and they also excel in stability. GaAs-type cells show significantly better spectral mismatch when compared to measurements using the combination of the commonly used "Si-type cell" and the colored glass filter KG-5 as a reference for perovskite-type cells. ReRa Solutions in the Netherlands is one of the few companies manufacturing high-quality GaAs-type reference solar cells, and we have established a system to provide stable supply and technical support within Japan, leveraging our know-how in the manufacturing and sales of our own reference solar cells. Our reference solar cells also comply with the standards of the WPVS (World Photovoltaic Scale) and the requirements of IEC 904-2. Additionally, cell calibration is conducted at the Radboud University Nijmegen PV Measurement Facility and is traceable to the NREL in the United States.

Mobile solar cell "Violetta Solar Gear VS01"

This is a solar charger for AA and AAA rechargeable nickel-metal hydride batteries, mobile phones, and portable AV devices.

Product Overview This is a pocket-sized universal portable solar power system that can charge AA and AAA batteries, as well as supply power to various small mobile devices such as mobile phones, PDAs, and portable AV equipment. It is the original mobile solar cell that has won the Good Design Award and the Special Award from the Small and Medium Enterprise Agency in 2001, known for its long life and long-selling history. Main Features It can charge two rechargeable nickel-metal hydride batteries "Violetta" in AA or AAA size (sold separately) simultaneously using solar power. Additionally, if you connect multiple units with a "DC power cable" (sold separately), you can achieve rapid charging. By attaching a "USB power adapter" (sold separately) and connecting it to mobile devices such as mobile phones, PDAs, and portable AV equipment with a DC input of 4V to 6V using commercially available USB charging cables, you can charge the batteries of those devices. If you pre-charge the rechargeable nickel-metal hydride batteries "Violetta," you can use them even when there is no sunlight. You can also supply power to mobile devices with a DC input of 3V by connecting them with a "DC power cable." If you pre-charge the rechargeable nickel-metal hydride batteries "Violetta," you can use them even when there is no sunlight.

Solar panels for space use

Design and manufacture of high-efficiency triple-junction GaAs solar cell panels for spacecraft such as ultra-small to medium-sized satellites.

We are engaged in the design and manufacturing of solar panels using high-efficiency triple-junction GaAs solar cells for space applications, including numerous ultra-small to medium-sized satellites. We cover a wide range from solar panels for ultra-small satellites and CubeSats to solar panels and deployment mechanisms for medium-sized satellites. Additionally, we offer services for attaching solar cells to honeycomb panels and CFRP substrates. Currently, while it has become quite difficult to obtain solar cells, we can design and manufacture panels in a short period due to our long-term supply contracts with solar cell manufacturers when providing solar panels. Furthermore, we can also provide solar paddle drive mechanisms (SADM) together.
