Highlights of mainstream solar cell efficiencies in 2024
Shanghai Jiao Tong University Journal Center2024 was an exciting year that all the single-junction
silicon, perovskite solar cells, and the perovskite/silicon
tandem solar cells have broken their world record power
conversion efficiencies. This paper continues our
highlights on the yearly highest independently confirmed
mainstream (silicon, perovskite and organic) solar cell
efficiencies and analyzes the progress of each cell
technology. We are also happy to see that the passivating
contact solar cells have been dominated the photovoltaic
(PV) market and the production capacity of the
perovskite solar cells has been reached to several
hundred-megawatt scale in 2024.

How fear of the unknown shapes the crypto fundraising landscape
Shanghai Jiao Tong University Journal CenterAbstract
Purpose – The market products produced by Initial Coin Offerings (ICO) platforms are often relatively new and have no previous transaction records and therefore are hard to estimate for its demand. The purpose is to study the impacts of the degree of ambiguity aversion of entrepreneurs to demand uncertainty on the ICO financing ratio, the optimal expected output, the optimal efforts and the token price.
Design/methodology/approach– In an optimal ICO design, we introduce demand uncertainty of the product and establish a robust optimisation method to solve the ICO optimal design. We compare ICO financing and the general venture capital (VC) financing model. We analyse the impact of demand uncertainty on the optimal ICO financing ratio.
Findings – Findings include that the ICF of financing ratio is positively related to the degree of ambiguity aversion, the token price is negatively related to the degree of ambiguity aversion and the “ambiguity premium” exists in the ICO market, the optimal effort levels are negatively related with the ICO financing ratio, but positively related with token price, and in the environment of high production cost, VC financing is not as good as ICO financing.
Originality/value – We develop a robust ICO financing model by assuming that the entrepreneur is ambiguity aversive to the demand uncertainty. Analyse the impact of the degree of ambiguity aversion on the ICO financing ratio in theory and find that the entrepreneur can raise funds with the higher ICO token ratio when she has a larger degree of ambiguity aversion to the demand uncertainty. Extend the impact analysis of the degree of ambiguity aversion on the expected token price and find a negative relationship between the expected token price and the degree of ambiguity aversion of the entrepreneur to the demand uncertainty.

Researchers pioneer ultrasound technology to measure blood viscosity
University of Missouri-ColumbiaFor years, doctors have relied on familiar vital signs — heart rate, blood pressure, temperature and oxygen levels — to monitor someone’s health. But researchers at the University of Missouri believe one key metric has been overlooked: blood viscosity, or how thick or sticky blood is as it flows through the body. And they’ve developed a breakthrough technology to monitor it non-invasively and in real time.
The first-of-its-kind device uses ultrasound waves to measure blood viscosity in real time — but the true innovation lies in its software. The system works by gently vibrating blood with a continuous sound wave — meaning it sends a steady sound wave through the blood while simultaneously sensing its response. Then, a powerful algorithm analyzes how the sound moves through the body.

Insuring the future: The insurance industry’s role in climate change mitigation
Tel-Aviv UniversityGlobal warming and extreme weather are changing the rules of homeowners’ insurance across the globe. In the United States, as a result of increasing damages from floods, the federal flood insurance program (NFIP) is making significant changes to reduce costly public subsidies for climate risks - a move that raises prices for the public, reduces availability of insurance, and can ripple through to real estate market.
