1. Sol-Chip™ EVAL-101
(including Saturn400)
The Sol Chip™ EVAL-101 allows for simple
configuration of the Sol Chip Energy
Harvester (Saturn400), with a pre-soldered
Sol Chip Saturn400 Photovoltaic chip on
board and additional soldering pads.
Sol Chip Energy Harvester (Saturn400) is a
unique Photo Voltaic (PV) cell which
produces six selectable voltage levels: 0.75
volt, 1.5 volt, 2.25 volt, 3 volt, 4.5 volt, 9 volt.
Each selectable voltage delivers different
current. See Table 1 below.
Saturn100 Product Specification
VOC(1):
0.75V, 1.5V,
2.25V, 3V,
4.5V, 9V
(2)
Max ISC at full daylight: 8.2 mAmp
Pmax at full daylight:
4.0 mWatt
Pmax at office light(3): up to 22 μWatt
(1) See Table 1
(2) For the case of VOC=0.75v. See Table 1.
(3) Depends on light conditions.
The maximum power which can be extracted
in full daylight is ~4.0 mWatt and in office
lighting the power extracted is up to
22 μWatt, dependent on ambient lighting
intensity.
Additional voltage levels and also several
voltage and power levels can be delivered
simultaneously from separate pins of the
device.

Advantage:
Dual Charge Storage: When Load current < PV current, the Storage Cap 1 is charged and enables charge
buffering. This will increase the energy efficiency.
* Primary Battery – Any “off the shelf” available non-rechargeable battery.
