Tandem solar cell configurations are provided where at least one of the cells is a metal chalcogenide cell. A four-terminal tandem solar cell configuration has two electrically independent solar cells stacked on each other. A two-terminal solar cell configuration has two electrically coupled solar cells (same current through both cells) stacked on each other. Carrier selective contacts can be used to make contact to the metal chalcogenide cell (s) to alleviate the troublesome Fermi level pinning issue. Carrier-selective contacts can also remove the need to provide doping of the metal chalcogenide. Doping of the metal chalcogenide can be provided by charge transfer. These two ideas can be practiced independently or together in any combination.

A low cost IC solution is disclosed to provide Super CMOS microelectronics macros. Hereinafter, the Super CMOS or Schottky CMOS all refer to SCMOS. The SCMOS device solutions with a niche circuit element, the complementary low threshold Schottky barrier diode pairs (SBD) made by selected metal barrier contacts (Co/Ti) to P— and N—Si beds of the CMOS transistors. A DTL like new circuit topology and designed wide contents of broad product libraries, which used the integrated SBD and transistors (BJT, CMOS, and Flash versions) as basic components. The macros include diodes that are selectively attached to the diffusion bed of the transistors, configuring them to form generic logic gates, memory cores, and analog functional blocks from simple to the complicated, from discrete components to all grades of VLSI chips. Solar photon voltaic electricity conversion and bio-lab-on-a-chip are two newly extended fields of the SCMOS IC applications.

A voltage-matched solar module for converting incident solar radiation into electricity consisting of a plurality of wafer-sized multi-junction solar devices and wiring circuitry adjacent to a module-sized bottom substrate. Each solar device has at least two photovoltaic (PV) cells separated by electrically insulating transparent layers.
