This paper introduces a novel control law and energy management algorithm tailored for a boost-derived three port converter (TPC) employed in a standalone PV system. This converter can be used to interconnect a PV array, a battery and a resistive load through its three ports. Thanks to the devised energy management strategy, the converter exhibits ...

Voltage-dependent Electroluminescence (ELV) measurements have been shown to mimic local diode current-voltage characteristics [1]. A corresponding physical model enables the derivation of two local parameters from ELV data measured on Silicon solar cells: a pseudo-recombination current J0* and a pseudo-series resistance Rs*. Various local character...
The accumulation of dust particles on solar collectors can gradually degrade optical performance in solar systems — a phenomenon known as soiling. Additionally, the formation of dew on collectors during early mornings introduces new mechanisms that can impact the soiling process. This study investigates the influence of dew on soiling for uncoated ...

The construction area of the Sichuan-Tibet Railway is located at a high altitude with thin air conditions, but it benefits from excellent solar irradiance. To address issues such as insufficient power and low efficiency of traditional fuel-based equipment in such harsh environments, electric equipment is being employed as a replacement for conventi...
The use of semiconductors based on abundant and less expensive materials in photovoltaic industry has grown since electricity consumption has increased, alloys such as Cu 2 ZnSn(S 1-x Se x ) 4 have recently attracted attention, due to its structural, optical and electronic properties which make it a very promising candidate as an absorber layer in ...
Photovoltaic-thermoelectric hybrid devices aim at harvesting the entire solar spectrum via both direct photovoltaic conversion and subsequent thermoelectric conversion of the heat generated in the solar cell. Oneemerging strategy to improve their efficiency is to implement a photothermal interface between the photovoltaiccell and the thermoelectric...
