Observations of broadband solar UV-A irradiance at Santa Maria, Brazil (29°S, 53° W) [PDF]

Geofísica Internacional, 2004
Observations of broadband solar UV-A irradiance (320-400 nm) were made at Santa Maria, Brazil (29° S, 53° W) between September 1993 and December 1996. Two different measurement techniques were used, the direct sun (DS) with the sensor pointed directly to

Attenuation Factor Estimation of Direct Normal Irradiance Combining Sky Camera Images and Mathematical Models in an Inter-Tropical Area

Remote Sensing, 2020
Nowadays, it is of great interest to know and forecast the solar energy resource that will be constantly available in order to optimize its use. The generation of electrical energy using CSP (concentrated solar power) plants is mostly affected by ...

Climate response to changes in atmospheric carbon dioxide and solar irradiance on the time scale of days to weeks

Environmental Research Letters, 2012
Recent studies show that fast climate response on time scales of less than a month can have important implications for long-term climate change. In this study, we investigate climate response on the time scale of days to weeks to a step-function ...

View Factors in Horizontal Plane Fixed-Mode Solar PV Fields

Frontiers in Energy Research, 2022
In solar PV fields, solar photovoltaic panels are typically arranged in parallel rows one after the other. This arrangement introduces variations in the distribution of solar irradiance over the entire field, compared to measurements recorded at ...

Measuring and modeling solar irradiance on vertical surfaces [PDF]

, 1986
This report presents the first evaluations of 5 algorithms for converting global horizontal and direct normal solar irradiance components to global irradiance on tilted surfaces using measurements from the Solar Radiation Research Laboratory (SRRL) at SERI. High resolution (15-min) measurements from 8 thermopile radiometers oriented vertically in the 4

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering

Advanced Functional Materials, EarlyView.
This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

Decoupling the effects of clear atmosphere and clouds to simplify calculations of the broadband solar irradiance at ground level [PDF]

Geoscientific Model Development, 2014
In the case of infinite plane-parallel single- and double-layered cloud, the solar irradiance at ground level computed by a radiative transfer model can be approximated by the product of the irradiance under clear atmosphere and a modification factor due
