Modelling photovoltaic power

open access: yesEngineering, Technology & Applied Science Research, 2015
A robust and reliable model describing the power produced by a photovoltaic system is needed in order to be able to detect module failures, inverter malfunction, shadowing effects and other factors that may result to energy losses. In addition, a reliable model enables an investor to perform accurate estimates of the system energy production, payback ...

Defect‐Free Block Copolymer‐Based Distributed Bragg Reflector for Optimized Light Harvesting in BiVO4 Photoanodes

open access: yesAdvanced Functional Materials, EarlyView.
A solution‐processed distributed Bragg reflector (DBR) film, integrated via block copolymer (BCP) self‐assembly, enhances photon recycling in BiVO4 photoanodes for improved photoelectrochemical (PEC) performance. By tuning lamellar structures using lactic acid and cross‐linking density, the DBR film optimally shifts working wavelengths, boosting ...

Composition and Resulting Band Alignment at the TiO2/InP Heterointerface: A Fundamental Study Combining Photoemission Spectroscopy and Theory

open access: yesAdvanced Functional Materials, EarlyView.
The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.
