Boosting Bifacial Output Power of Ag‐CIGS Solar Cells by Optimizing ITO Back‐Contact Thickness for Tandem Applications

Carbon Energy, EarlyView.
Optimized ITO back contact with pre‐Ga supply growth and Ag incorporation suppresses GaOx formation and interface recombination in bifacial CIGS solar cells. The devices achieve 17.25% front and 5.77% rear efficiency, delivering record bifacial power density up to 32.26 mW cm−2 in 4T perovskite/CIGS tandem architectures under enhanced albedo ...

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

The Role of Current Mismatch on Reverse‐Bias Stability of Monolithic Perovskite/Silicon Tandem Solar Cells

EcoEnergy, EarlyView.
Reverse‐bias stability in monolithic perovskite/silicon tandem solar cells requires a silicon–current‐limited regime. When the perovskite current exceeds the silicon current, the reverse voltage is mainly borne by the silicon cell, reducing perovskite stress.

Solar Variability in the Mg ii h and k Lines

The Astrophysical Journal
Solar irradiance and its variations in the ultraviolet (UV) control the photochemistry in Earth's atmosphere and influence Earth's climate. The variability in the Mg ii h and k core-to-wing ratio, also known as the Mg ii index, is highly correlated with ...

Characteristics of solar UV irradiance

Meteorologische Zeitschrift, 1994
Solar UVB irradiance is measured worldwide with the Robertson-Berger sunburn meter whose spectral sensitivity is adapted to the action spectrum of human erythema. Thus, the Robertson-Berger sunburn meter measures the erythemal effective irradiance.
