Abstract
An apparatus for facilitating a measurement of characteristics of a photovoltaic cell. The apparatus includes an input port for coupling to a photovoltaic cell and an output port for coupling to a measurement equipment. The apparatus is configured to couple a first resistor across positive and negative inputs of the input port and a second resistor between the negative input and ground when the input port is not selected or inactive, and decouple the first and second resistors from the input port when the input port is selected and active. The apparatus couples the positive input of the input port to the output port when the input port is selected but inactive or selected and active. The resistors protect the photovoltaic cell from adverse consequences due to incident ambient light. Examples of multiple port versions of the apparatus are also disclosed.
