Indoor photovoltaics (IPVs) can sustainably power the growing smart-device ecosystem, yet they are commonly designed and evaluated using human-vision metrics and arbitrary spectra, impairing progress. Khampa et al. propose a universal, spectrum-aware framework for IPV design and benchmarking. By charting realistic indoor lighting diversity, they reveal an expanded optimal band-gap range (1.45–2.1 eV), introduce the spectral onset at 95% cumulative irradiance to unify IPV trends, and implement locus-based benchmarking to capture full efficiency spaces of IPVs, enabling fair cross-device comparisons.

Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

A new study from SFU's School of Sustainable Energy Engineering (SEE) proposes an innovative standardization framework to overcome long-standing inconsistencies in testing indoor solar technology—enabling reliable efficiency measurements and accelerating progress toward practical, sustainable indoor energy harvesting.
