High-Reflectivity Ground Covers for Energy Yield Enhancement in Single-Axis Tracked Bifacial Photovoltaic Systems: Field Evidence from Brazil

Energies
Artificial high-reflectivity ground covers are a potential strategy to increase rear-side irradiance and energy yield in bifacial photovoltaic systems, especially in utility-scale plants with single-axis trackers. This paper reports field evidence from a

Luminescence Thermometry on the Route of the Mobile‐Based Internet of Things (IoT): How Smart QR Codes Make It Real

Advanced Science, Volume 6, Issue 19, October 2, 2019., 2019
Organic–inorganic hybrid materials doped with Eu3+ and Tb3+ are processed asluminescent Quick Response (QR) codes, simultaneously doubling the storage capacity and sensing the temperature using a photo taken with a smartphone. The developed methodology yields a maximum relative thermal sensitivity of 5.14% · K−1 and a minimum temperature uncertainty of

Analytical Modelling of High Concentrator Photovoltaic Modules Based on Atmospheric Parameters

International Journal of Photoenergy, Volume 2015, Issue 1, 2015., 2015
The goal of this paper is to introduce a model to predict the maximum power of a high concentrator photovoltaic module. The model is based on simple mathematical expressions and atmospheric parameters. The maximum power of a HCPV module is estimated as a function of direct normal irradiance, cell temperature, and two spectral corrections based on air ...

RMS Current of a Photovoltaic Generator in Grid‐Connected PV Systems: Definition and Application

International Journal of Photoenergy, Volume 2008, Issue 1, 2008., 2008
This paper includes a definition of a new and original concept in the photovoltaic field, RMS current of a photovoltaic generator for grid‐connected systems. The RMS current is very useful for calculating energy losses in cables used in a PV generator. As well, a current factor has been defined in order to simplify RMS current calculation.

To Greater Twist: A Kinetically Biased π‐Radical Cascade

Angewandte Chemie International Edition, EarlyView.
π‐Radical cascades enable step‐economic construction of complex polycyclic aromatic frameworks. In this work, we show that a multifurcating pathway can be kinetically steered toward a single, more distorted product. This counterintuitive “falling‐upward” outcome arises from an intrinsic mechanistic bias, revealing a broader dimension of control in π ...
