CONTEXT: INTERNET OF THINGS
• IoT = 3rd revolution of internet
• Exponential number of applications, fields of industrial and environmental monitoring,
energy management, building and home automation
• Major Concern = Powering and autonomy of these objects, wireless
• Need of ENERGY HARVESTING

• Performance measurement
• PCE (%) = Pmpp / Pinput
• Under one SUN AM1.5: Pinput = 1000 W/m²
• Variation of the inpunt power: VIM studies
• Under low light: response not linear, function of the intensity and of the light
source
• Indoor Sources
• LED, fluorescent lamp, neon tube
• From 200 lux to 1000 lux
