Multi-scale solar-to-hydrogen system design: An open-source modeling framework

Hydrogen produced from renewable energy holds significant potential in providing sustainable solutions to achieve Net-Positive goals. However, one technical challenge hindering its widespread adoption is the absence of open-source precise modeling tools for sizing and simulating integrated system components under real-world conditions. In this work, we developed an adaptable, user-friendly and open-source Python (R) model that simulates grid-connected battery-assisted photovoltaic-electrolyze...

Inverted perovskite solar modules with 99.3% geometrical fill factor via nanosecond single laser patterning

Perovskite solar cells (PSCs) hold promise for high-efficiency photovoltaic technology but face commercialization challenges due to scaling difficulties. A common approach for scaling PSCs involves creating perovskite solar modules (PSMs) with subcells connected in series, using P1, P2, and P3 laser scribing process to reduce interconnection losses. In this study, a standard nanosecond pulse UV laser was used to perform these scribes. Here we demonstrated that, by employing a single 45 mu m l...

Advances in the pyrolysis of end-of-life tires: A critical review of reactor systems, process conditions and industrial applications

The growing environmental concerns and increasing volumes of end-of-life tires (ELT) have driven global interest in sustainable recycling solutions. Pyrolysis has emerged as a promising thermochemical process for converting waste tires into valuable materials, including tire pyrolysis oil (TPO), gas, and recovered carbon black.

Unlocking the potential of semi-transparent Ta3N5 photoelectrodes for high-performance, reproducible solar redox flow cells

A solar redox flow cell (SRFC) converts solar energy into storable electrochemical energy and heat; when connected to a redox flow battery, it can produce dispatchable electricity. Despite its versatility, a SRFC is still considered to be at a low technology readiness level (TRL), mainly due to the absence of abundant, efficient, and stable semiconductors. Tantalum nitride (Ta3N5) photoelectrodes have garnered special interest for photoelectrochemical water-splitting applications, particularl...
