Bifacial SHJ solar cells using a transparent-conductive-oxide-free and intrinsic ZnOX-based electron-selective passivating contacts are developed, showing a J SC bifaciality up to 97%. With both side finger metal electrodes contact, this bifacial solar cell shows an efficiency of 21.2% under front-side irradiation and 20.4% under rear-side irradiation,...

The objective of this work is to evaluate and optimize the screen-printed front side metallization for silicon heterojunction (SHJ) solar cells. Three iterative experiments are conducted using different screen configurations and grid layout parameters. A batch of SHJ cells is metallized with an optimized front side grid layout using a knotless fine...

This work presents the development of novel IBC-SHJ solar cells with a MoO x blanket layer aiming to simultaneously enable a simplified device processing and a high shunt resistance in the device. The fabricated solar cells exhibit efficiencies up to 21.14% with high shunt resistances above 150 kΩcm2. Abstract The fabrication process...

PID is caused by the movement of Na from the PV module glass due to leaching phenomenon. The PID reduction effect was confirmed by preventing leaching by coating with PTFE, a hydrophobic material. Abstract As photovoltaic (PV) modules are exposed to high temperatures and humidity over time, they generate leakage current, which leads to potential-induced...

The acquisition and quantitative analysis of photoluminescence images in full daylight using switching of modules' operating points via the system inverter is demonstrated on both residential rooftop and utility scale photovoltaic systems, including the demonstration of simultaneous photoluminescence image capture of hundreds to thousands of modules...

In this study, researchers developed durable, non-porous multifunctional multilayer coatings (MLCs) as a spectrally selective filter for solar modules. Comprehensive investigations compared MLCs with conventional antireflective coatings, revealing superior durability and reduced parasitic heat absorption. A techno-economic analysis model was developed...
