Abstract
A photovoltaic cell set (10). The set (10) includes at least one conductive layer (21, 23; 25, 25′) over a top face of the substrate (22; 28) or a bottom faced of the substrate (22; 28) to establish an electrical contact of the photovoltaic cells (2, 12). At least one large-size first photovoltaic cell (2) is provided to capture light energy to be converted into electrical energy in a module (1). At least one small-size second photovoltaic cell (12) independent of the first photovoltaic cell (2) is provided. It is arranged to measure in the module (1) a voltage or a current to optimise the operation of the module (1).
Claims19
A photovoltaic cell set configured to be part of a photovoltaic cell module with an electronic circuit, comprising:
- at least one large-size first photovoltaic cell, which is arranged to capture light energy to be converted into electrical energy in the module,
- at least one small-size second photovoltaic cell independent of the first photovoltaic cell, which is arranged to measure in the module a voltage or a current to adapt an operating point of the module,
- a substrate suited for making one or more photovoltaic cells,
- a first conductive layer arranged over a top face of the substrate,
- a second conductive layer arranged over a bottom face of the substrate,
- an insulation is made to define the first photovoltaic cell, and
- another insulation is made to make the second photovoltaic cell independent of the first photovoltaic cell so as to enable the second photovoltaic cell to perform the measurement of the voltage or of the current in the module,
- wherein the insulation and the another insulation extend at least from the first conductive layer through the substrate to the second conductive layer.
