The Promising Growth Of The Organic-Inorganic Perovskite Solar Cells (Psc) Efficiency And Durability Has Led To Development And Research Towards Commercialization Through High Throughput Automated Manufacturing Of These Photovoltaic (Pv) Devices. Rapid Thermal Annealing Of The Deposited Metal Oxide Layers And The Photoactive Layer, Along With The Use Of Additives, Can Potentially Diminish Device Fabrication Time And Enhance Device Performance Through Improved Thin Film Characteristics. Applying Millisecond Pulses Of Energetic Light Can Form High-Quality Morphology For The Transparent Conductive Oxide Electron Transport Layer As Well As The Perovskite Absorber Film. It Was Observed That The Addition Of An Alkyl Halide, Such As Diiodomethane (Ch2I2), To The Perovskite Photoactive Layer Could Considerably Improve The Power Conversion Efficiency (Pce) Of The Cells Through Stitching The Grain Boundaries That Act As Charge Recombination Centers. This Manuscript Spans The Material Characterization Results Of The Rapidly Sintered Sno2 Electron Transport Layer And The Ch2I2 Assisted Mixed Cation Perovskite Films Through Scanning Electron Microscope (Sem) As Well As X-Ray And Ultraviolet Photoelectron Spectroscopy (Xps And Ups) Techniques. It Was Observed That The Synergy Of Millisecond Pulsed Annealing And Ch2I2 Additive Could Enhance The Psc Photovoltaic Parameters, Resulting In An Increase From 6.45% For The Pristine Devices To 11.34% Efficiency For The Mixed Cation Psc With Pulsed Annealing, When Processed In The Ambient With Humidity Of About 60%. This Manuscript Highlights The Significance Of Intense Pulsed Light On Rapid Annealing Of The Thin Films As Well As The Impact Of Released Halide From The Alky Halide To Boost The Quality Of Absorber Films, Which Can Be A Potential Candidate For High Throughput Automated Fabrication Of Psc.

Contacting advanced industrial wafer silicon cells: challenges and solutions for test labs and equipment manufacturers

As silicon PV technology advances the contact patterns on industrial wafer silicon solar cells are rapidly evolving. Multiple patterned busbars and busbar-less cells can increase efficiency and reduce cost. These changes present significant challenges for calibration labs. As contact patterns and cell interconnections in modules evolve, even the concept of Isc for STC calibration of wafers becomes blurry. Do we need to consider a new standard to ensure that wafer calibrations continue to be meaningful? Join speakers from major calibration labs, equipment suppliers, and PV manufacturers in this informal symposium to discuss challenges and solutions presented by the rapid evolution of wafer contact patterns.
