Here Comes the New Efficiency Record of indoor mono-Si PV – 23.97%

Overcoming the challenge of weak and indoor lighting has long been a significant hurdle for crystalline Si PVs due to mismatched energy bandgap and the low power density of artificial lamps. For instance, a 1000 lux T5 lamp has an energy density of just 0.19 mW/cm², about 2/1000 that of sunlight (1 Sun = 100 mW/cm²). Under such conditions, conventional crystalline Si typically achieves around 10-12% efficiency.

In 2023, FLEXWAVE’s waveguide PV technology revolutionized the field by pushing the power conversion efficiency of mono-Si based PV modules beyond 20% under fluorescent light for the first time (employed 22% PERC). This milestone was showcased at EUPVSEC; menawhile, the waveguide encapsulation enables to capture photons from an incident angle of 176 degrees, as demonstrated through the masking experiments.

This year, we’ve broken our own record by pairing this technology with the latest 24.6% TOPCon solar cells, achieving an unprecedented 23.97% for mono-Si based PVs under indoor lighting conditions certified by the Photovoltaics Calibration Labotary of ITRI. This remarkable performance enhancement proves that the micro-concentration benefits of waveguide can effectively address the bandgap mismatch, enabling high-efficiency monocrystalline silicon cells to maintain substantial power output even in low-light environments.

This mass-produced module not only puts mono-Si at the forefront of the low-light energy harvesting market but also declares a competitive efficiency compare to the commercialized thin-film PVs. Additionally, silicon materials boast a proven track record of over 40 years of durability in outdoor applications, which ensuring extremely reliable performance both indoors and out.

Join us in celebrating this groundbreaking achievement as we continue to lead the way in energy harvesting innovation and deliver the best performance for the Smart and Net Zero future!
