Diode cell modules for use within photovoltaic systems, including lead frames including first leads extending from the first outlet terminal, second leads spaced from the first leads, second outlet terminals extending from the second leads, and diodes. In some examples, first leads define base portions connected to the first outlet terminal and diode portions extending from the base portions transverse to the first outlet terminal. In some examples, second leads may define a base portion and diode portions extending from the base portion substantially parallel to the diode portion of the first lead. In some examples, diodes may be in electrical contact with the diode portion of the first lead and with the diode portion of the second lead. In some examples, the first leads and second leads may be thermally conductive. In some examples, diodes may define die interfaces that are substantially fully engaged with diode portions of leads.
