Photovoltaic Cells In Low-Light Operation

Abstract

Comparison of the properties of respective technologies shows that for low-light operation there are most advantageous inorganic thin film cells. It is very important to consider the operating conditions and adapt the selection of the photovoltaic cell to these conditions. Because of very small area of the cell needed for the low energy converters the price of the photovoltaic cell is not an important item in the total cost of an Enargy Harvesting converter. Simple and reliable low price JFET driven DC to DC converter was designed for this application.
