Among numerous fluorophores for LSCs, carbon quantum dots (C-QDs) are promising candidates due to their non-toxic nature, tunable optical features, and cost-effective synthesis. State-of-the-art LSCs utilizing C-QDs focus on solar energy harvesting, while their potential to harness indoor light for electricity generation is yet to be explored. In this study, we rationally fabricated C-QDs based LSC for efficient energy harvesting under both outdoor and indoor illuminations.

Why use a whole orchestra when you can play a solo? With traditional solar systems, there are 8 modules performing 12 functions before energy reaches the grid. That means higher installation costs, lower system efficiency, and complex operation and maintenance processes. At Daanaa, we've simplified everything—direct AC output, faster MPPT, and real-time diagnostics—all from as few as 3 cells. The result? Up to 70% more energy from the same surface area. I'll be at RE+ next week; let's connect and talk about how we can help your solar systems perform at their best! #REPlus #solar #clean_energy #innovation #energy #electricity #powergeneration

Solar panels work at night now? It’s true! Researchers have developed a way to harness heat from infrared light to generate energy after dark. The bad news is that this method produces about 100,000 times less energy than conventional solar panels. So, whilst it's an impressive step forward, it might be a while before we see it on a rooftop. Link to the research paper: https://lnkd.in/efFaAUZs

It’s Highlight-Monday! Every Monday I will be highlighting a new article of our department, showing you more insights on our studies!🌊☀️ Today I will focus on #fpv and @Monica Nicolas Article on “Improving Module Temperature Prediction Models for Floating Photovoltaic Systems: Analytical Insights from Operational Data” (https://lnkd.in/eSWQ-uNn.) In this article, Monica Nicola reviews the applicability of existing module temperature prediction models, originally designed for land-based PV systems, to #fpvsystems. It details how these models are refined using FPV-specific data and validated through large-scale, ongoing #fpvprojects. The result? A notable improvement in temperature prediction accuracy, shown by reduced Mean Absolute Error (MAE) and enhanced R-squared (R²) values after parameter optimization.  Caught your attention? Follow the link below to read the full article! Stay tuned for more insights on the topic and look out for the next paper of this series! ☀️

【Numerical Analysis on the Effect of n-Si on Cu(In, Ga)Se2 Based Thin-Films for High-Performance Solar Cells by 1D-SCAPS】 Full article: https://lnkd.in/gzvJf62m (Authored by Rasika N. Mohottige, et al., from Waldorf University, USA.) Recently, worldwide research interest in cadmium telluride (CdTe) and chalcopyrite Cu(In, Ga)Se2 (CIGS) based #solar_cells has caused considerable interest within the photovoltaic community due to their excellent power conversion efficiencies (PCE) and cost-effectiveness. This work reports the performances of a chalcopyrite Cu(In, Ga)Se2 CIGS-based #thin_film solar cell with a newly employed high conductive n-Si layer, and extensively analyzes the impacts of the absorber layer's bandgap, thickness, and defect density on output solar cell performances.

I’m excited to announce the publication of my first article in MDPI’s Clean Technologies journal! https://lnkd.in/dYukWVmC This paper deals with proton exchange membrane (PEM) electrolyzers directly coupled with a photovoltaic source. It proposes a method to increase the energy delivered to the electrolyzer by reconfiguring the electrical connection of the arrays according to solar radiation. Unlike the design criterion proposed by the literature, the suggested approach considers a source obtained by connecting arrays in parallel depending on solar radiation based on a fixed photovoltaic configuration. This method allows for the optimization of the operating point at medium or low solar radiation, where the fixed configuration gives poor results. In the proposed study, an increase of 17%, 62%, and 93% of the delivered energy has been obtained in three characteristic days, summer, spring/autumn, and winter, respectively, compared to the fixed PV configuration. These results are also better than those achieved using the converter. Results show that the proposed direct coupling technique applied to PEM electrolyzers in low-power plants is a good trade-off between a fixed photovoltaic source configuration and the use of a DC/DC converter.

I'm delighted to announce that our recent research paper, co-authored with Matthew Berwind, "Improving Module Temperature Prediction Models for Floating Photovoltaic Systems: Analytical Insights from Operational Data", has been published in the Energies MDPI journal's special issue on floating PV . This paper addresses a key gap in our understanding of the thermal behaviour and claimed cooling effects of FPVs. The applicability of common models for predicting module temperature to FPVs is investigated. The models are then tuned using a large, ongoing FPV project and validated using another FPV project.
