THE INDUSTRIAL ACPL-K308U PHOTOVOLTAIC DRIVER IS DESIGNED TO DRIVE HIGH VOLTAGE MOSFETS

The industrial ACPL-K308U photovoltaic driver is designed to drive high voltage MOSFETs. It consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to an output detector circuit. The detector consists of a high-speed photovoltaic diode array and a turn-off circuit. This photovoltaic driver turns on (contact closes) with a minimum input current of 5 […]

RESEARCHERS DEVELOPED HIGHLY DURABLE WASHABLE AND STRETCHABLE SOLAR CELLS

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 published in the journal Nature Energy and illustrated

Using a supercapacitor for power management and energy storage with a small solar cell, Part 2

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, to power a

Heliatek sets new Organic Photovoltaic world record efficiency of 13.2%

Heliatek R&D teams reached a record conversion efficiency of 13.2% for an OPV multi-junction cell, setting a new world record for the direct conversion of sunlight into electricity using organic photovoltaic cells. The measurement was independently confirmed by Fraunhofer CSP. Thanks to the excellent low light and high temperature behavior of the organic semiconductor, the
