Diamond: The Ultimate Material for Semiconductors Since 2000, China has become the world’s largest producer of synthetic diamonds, with over 90% of the global production of diamond single crystals. The chemical composition of diamond is carbon (C), which is a polymorph of the carbon element and is currently the hardest known natural material. Diamonds can … Read more
Research Background Perovskite materials have become an ideal choice for next-generation photovoltaic materials due to their excellent optoelectronic properties and low-cost manufacturing processes. They are widely used in solar cells, photodetectors, and light-emitting devices. Compared to traditional silicon-based materials, perovskite materials offer significant advantages such as higher light absorption efficiency, broader spectral response, and lower … Read more
Regarding the reference voltage of the ADC, I have found that many engineers do not have a clear understanding. This is especially true in scenarios where the battery directly powers the MCU and the ADC is used. This article provides a brief summary. Taking the classic STM32F103 as an example, the reference voltage for the … Read more

Fully perovskite tandem solar cells exhibit excellent performance and a wide range of applications. However, bridging the gap in power conversion efficiency between small-area and large-area (>1 cm2) devices remains a significant challenge, posing a substantial barrier to the commercialization of fully perovskite tandem solar cells. In light of this, on April 17, 2025, Ke … Read more
