Saelig Company, Inc. (www.saelig.com) has introduced the patented Sol Chip Saturn802 Energy Harvester IC – a unique photovoltaic (PV) cell which can produce output voltage levels of 0.75V, 1.5V, 2.25V, 3.0V, 4.5V, and 9V, which existing solar cells cannot do. The maximum power which can be obtained in full daylight is around 10mW, or 55uW […]

In recent decades, humans realized that fossil fuels are a finite source of energy that not only pollutes the environment but is also difficult to extract (it can even be dangerous). Because of this, there has been a huge increase in the development of new ways to extract energy from other sources such as solar,

Bismuth is considered as a “green-element” and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of the University of Cambridge and the United States developed theoretical and experimental methods to show that bismuth, which sits next to lead (Pb) on the periodic table, can be used to make inexpensive solar cells.

Ideation I build connected sensors, which are often deployed in local parks where there is no access to utility power. Over the past couple years, I have been refining and testing my solar power modules, and have arrived at this compact integrated design. I have a number of these deployed and they have been in
Scientists of Japanese research institute RIKEN and the University of Tokyo have successfully developed a product that allows solar cells to continue to provide solar power after being washed, stretched and compressed. Takao Someya of Riken Center for Emergent Matter Science, a designated national R&D Institute in Japan, led the research team. The research results were

In Part 1 of this series, we have reviewed solar cell performance, how to select and size the supercapacitor, requirements of supercapacitor charging circuits and charging IC characteristics. We will now use two case studies to illustrate these properties in detail. Case Study 1: Using a small solar cell indoors at low light, 100 lux,
Description Solar power is not trivial, especially if it needs to be reliable and have a long lifetime for outdoor deployment such as IoT sensor nodes. This project is an effort to create a complete, easy to use solar power system that provides the following features: – LiFePO4 battery for high charge cycle count, high
