Standardized assessment of PV array simulators

open access: yesEPJ Photovoltaics
PV array simulators are devices for PV and PV battery inverter testing. To ensure that these devices operate correctly and can realistically simulate PV modules and PV arrays, a test procedure for the assessment of PV array simulators has been developed ...

Multi-objective design optimisation of standalone hybrid wind-PV-diesel systems under uncertainties [PDF]

open access: yes, 2014
Optimal design of a standalone wind-PV-diesel hybrid system is a multi-objective optimisation problem with conflicting objectives of cost and reliability. Uncertainties in renewable resources, demand load and power modelling make deterministic methods of

Enhanced Hole Extraction of WOx/V2Ox Dopant‐Free Contact for p‐type Silicon Solar Cell

open access: yesAdvanced Materials Interfaces, 2022
Nonstoichiometric vanadium oxide V2Ox has been demonstrated to serve as a hole‐selective contact in crystalline silicon solar cells. A reaction between V2Ox deposited by thermal evaporation and silicon can, however, result in a decreased work function ...
