The CL0116 Solar Lantern Controller IC
When voltage from the solar cell falls below 150mV the IC will switch into illumination mode and start powering the LEDs. Rather than a typical current limiting configuration, the IC slightly overdrives the LEDs but uses a 100KHz pulse-train to drive them which they suggest results in >90% efficiency.

Common Solar Inverter Error Codes & Solutions
Regular maintenance will prevent some of the situations that cause inverter failure and improve the lifespan of your inverter. But generally, solar inverters don''t outlast solar panels. While solar panels have a 25 – 30 years lifespan, solar inverters have about 10 – 15
FUNDAMENTAL PROPERTIES OF SOLAR CELLS
The open-circuit voltage, Voc, is the maximum voltage available from a solar cell, and this occurs at zero current. The open-circuit voltage corresponds to the amount of forward bias on the solar cell due to the bias of the solar cell junction with the light-generated current. The open-circuit voltage is shown on the IV curve below.
Open Circuit Voltage
The short-circuit current density is the photocurrent generated by the solar cell, expressed in the form of the current density under zero external field (i.e., 0 V). The flow of the photogenerated carriers to the electrode primarily depends on the built-in field of the solar cell. The short-circuit current density can be estimated as [45]:

How a Solar Cell Works
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …
