INDOOR SOLAR CELLS OPTIMISED TO CONVERT AMBIENT INDOOR LIGHT TO ELECTRICITY

INDOOR SOLAR CELLS OPTIMISED TO CONVERT AMBIENT INDOOR LIGHT TO ELECTRICITY

Swedish and Chinese scientists have developed organic solar cells optimised to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019-2029.   As the internet of

MPPT Based Charge Controller Using Pic Microcontroller

MPPT Based Charge Controller Using Pic Microcontroller

In this post we will briefly discuss about MPPT Based Charge Controller Using Pic Microcontroller. Photovoltaic is one of the renewable energy resources that recently has become broader in nowadays technology.  The electricity generations of photovoltaic (PV) panels are strongly related with insolation and temperature. The insolation and temperature are not stable, since the electricity

How to Select a Voltage Regulator

How to Select a Voltage Regulator

All electronics projects need power. Power can come from either stored energy in a battery, or directly from mains AC voltage or DC power from renewable sources such as solar energy. Power Management ICs (PMICs)help manage the power requirements in a system including scaling voltages, battery charging, and DC-DC conversion. Choosing the right PMIC can make
