Below the Urbach Edge: Solar Cell Loss Analysis Based on Full External Quantum Efficiency Spectra
Stefaan De Wolf, Jakub Holovsky, Randall Ellingson, Xin Yu Chin
We suggest a new solar cell loss analysis using theexternal quantumefficiency (EQE) measured with sufficiently high sensitivity to alsoaccount for defects. Unlike common radiative-limit methods, wherethe impact of deep defects is ignored by exponential ext ...
AMER CHEMICAL SOC2023Photo‐Electrochemical Conversion of CO 2 Under Concentrated Sunlight Enables Combination of High Reaction Rate and Efficiency
Sophia Haussener, Silvan Suter, Etienne Boutin, Mahendra Patel
Photo-electrochemical production of solar fuels from carbon dioxide, water, and sunlight is an appealing approach. Nevertheless, it remains challenging to scale despite encouraging demonstrations at low power input. Higher current densities require notable ...
Wiley2022Optimized market value of alpine solar photovoltaic installations
Jérôme François Sylvain Dujardin, Annelen Kahl
Solar photovoltaic (PV) is the most rapidly expanding renewable resource worldwide. Yet, its full potential may be hindered by mismatches with market demand and correlated production profiles. In this research, we explore a case study of innovative PV plac ...
2022The emergence of concentrator photovoltaics for perovskite solar cells
Mohammad Khaja Nazeeruddin, Anurag Roy
The emergence of high-efficiency photovoltaic research is undergoing intense study and is technologically desirable to meet sustainable energy and environmental demand. However, every single solar cell has a theoretical power conversion efficiency limit, a ...
AIP Publishing2021Emerging perovskite quantum dot solar cells: feasible approaches to boost performance
Lead halide perovskite quantum dots (PQDs), also called perovskite nanocrystals, are considered as one of the most promising classes of photovoltaic materials for solar cells due to their prominent optoelectronic properties and simple preparation technique ...
ROYAL SOC CHEMISTRY2021Parallel PV Configuration with Magnetic-Free Switched Capacitor Module-Level Converters for Partial Shading Conditions
Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Georgios Kampitsis
In this paper, a module-level photovoltaic (PV) architecture in parallel configuration is introduced for maximum power extraction, under partial shading (PS) conditions. For the first time, a non-regulated switched capacitor (SC) nX converter is a used at ...
2021The bright side of PV production in snow-covered mountains
Michael Lehning, Jérôme François Sylvain Dujardin, Annelen Kahl
Our work explores the prospect of bringing the temporal production profile of solar photovoltaics (PV) into better correlation with typical electricity consumption patterns in the midlatitudes. To do so, we quantify the potential of three choices for PV in ...
2019A comprehensive experimental study of five fundamental phenothiazine geometries increasing the diversity of the phenothiazine dye class for dye-sensitized solar cells
Phenothiazine is a versatile scaffold frequently used in both pharmaceutical and photovoltaic applications. Still, the structural diversity within the class of phenothiazine sensitizers for dye-sensitized solar cells is minute. Substituents are found in 3, ...
ELSEVIER SCI LTD2019Quantifying and modeling the impact of interconnection failures on the electrical performance of crystalline silicon photovoltaic modules
