Patent number: 11870002Abstract: According to embodiments provided herein, the performance of photovoltaic device can be improved by rapidly heating an absorber layer of a device in open-circuit to a high temperature for a short period of time followed by rapid quenching. The rapid heating may be accomplished by one or more pulses of high intensity electromagnetic energy. The energy may be visible light. The energy may be absorbed primarily in the absorber layer, such that the absorber layer is preferentially heated, promoting chemical reactions of dopant complexes. The dopant chemical reactions disrupt compensating defect complexes that have formed in the device, and regenerate active carriers.Type: GrantFiled: May 13, 2021Date of Patent: January 9, 2024Assignee: First Solar, Inc.Inventors: Dmitry Krasikov, Sachit Grover, Igor Sankin

Patent number: 11846041Abstract: The present disclosure provides a method for facet-selective passivation on each crystal facet of colloidal nanocrystals via solution-phase ligand exchange process, thereby providing highly-passivated and colloidally-stable nanocrystal inks. This ligand exchange strategy separately addresses polar and non-polar facets precluding from deleterious nanocrystal aggregation in the colloid. The method involves the introduction of alkali metal organic complexes during metal halide conventional solution exchanges, and one specific example is Na+·Ac?. Alkali metal ions stabilize and passivate non polar facets whereas polar facets are passivated through metal halides. This strategy leads to a significant decrease in nanocrystal aggregation during and after ligand exchange, and to improved photophysical properties stemming from this. The resulting nanocrystal solid films exhibit improved stability, retain their absorption features, and have a minimized Stokes shift.Type: GrantFiled: May 14, 2019Date of Patent: December 19, 2023Assignee: QD SOLAR INC.Inventors: Younghoon Kim, Fanglin Che, Jea Woong Jo, Jongmin Choi, Francisco Pelayo Garcia De Arquer, Sjoerd Hoogland, Edward H.
