#upconversion

Scientists in Australia have developed a process for calculating the perfect size and density of quantum dots needed to achieve record efficiency in solar panels.

Quantum dots, human-made nanocrystals 100,000 times thinner than a sheet of paper, can be used as light sensitisers, absorbing infrared and visible light and transferring it to other molecules.

This could enable new types of solar panels to capture more of the light spectrum and generate more electrical current, through a process of 'light fusion' known as photochemical upconversion.

The researchers, from the ARC Centre of Excellence in Exciton Science, used lead sulfide quantum dots in their example. The algorithm is free to access and their results have been published in the journal Nanoscale.

Significantly, existing upconversion results achieved by test devices used organic sensitisers that do not work with silicon solar cells -- currently the most commonly available type of photovoltaics technology -- due to their inability to absorb much of the infrared part of the light spectrum.

In today’s fast-evolving digital landscape, legacy videos often face significant challenges when adapted for modern platforms. Whether it's older films, archival footage, or corporate videos, scaling these assets to meet today’s high-resolution standards can be complex. Low resolution, outdated formats, and poor compatibility with current display technologies often hinder their usability.

This is where Prasad Corp’s UpRez services come into play, delivering cutting-edge solutions for Up-Conversion that breathe new life into legacy content.

Why Legacy Content Needs More Than Just Resizing

Legacy videos, created in standard definition or lower resolutions, do not naturally fit the requirements of 4K TVs, streaming platforms, or large-format displays. Simply stretching or resizing these videos leads to pixelation, loss of detail, and poor viewer experience.

Prasad Corp’s proprietary UpRez technology addresses this challenge using advanced algorithms and AI-driven processes to intelligently upscale video frames. This preserves original textures, enhances clarity, and restores fine details — without introducing artifacts or distortion.

Stimulating deeper with near-infrared

Interesting idea in this post at Labrigger:

Compared to visible (vis) light, near infrared (NIR) wavelength scatters less and is less absorbed in brain tissue. If your fluorescent target absorbs vis light, then one way to use NIR is to flood the area with molecules that will absorb NIR and emit vis light. The process is called “upconversion“, since it is in contrast to the more common process of…
