Japan Solar Update: No.127 (Dec 16 ~ 20, 2024)
NTT Advanced Technology Corporation (NTT-AT) has begun providing engineering samples (ES) of its innovative SQPV Glass (Version 2) to stakeholders as part of preparations for mass production in November 2024.
Since 2020, NTT-AT has collaborated with the venture company inQs to develop and promote transparent solar photovoltaic (PV) glass using nano-processed silicon dioxide technology. This revolutionary material integrates renewable energy solutions into everyday materials while maintaining a transparent appearance.
The SQPV Glass (V2) uses an 11×6 multi-cell structure, offering a significant increase power output compared to conventional 30 cm square single-cell design, and also improves material quality to achieve power generation efficiency of 1%, power generation performance of more than 50 MW under irradiance of 100 W/m², and a visible light transmission rate of over 56%.
Breakthrough in Energy and Sustainability SQPV Glass goes beyond electricity generation. Its heat-shielding properties reduce energy consumption for air conditioning, contributing to urban heat island mitigation. Furthermore, its ability to generate power under low-light conditions—such as indoors or on north-facing surfaces—makes it a versatile and practical energy solution that can generate power exactly where it is needed.
