Integration of Solar Cells on Top of CMOS Chips—Part II: CIGS Solar Cells

State of the art in Microfabrication

“…Various groups investigate photovoltaic systems-on-foil, a technology that could offer extremely low-radiation length semiconductor junctions, an attractive feature for particle tracking. Alternatively, the photovoltaic technology may be transferable directly to a CMOS pixel readout chip, as has been shown for a-Si and CIGS [33][34][35][36].…”

D7.4 - CMOS integrated miniaturized photovoltaic cells for autonomous sensor nodes: simulations and experimental results

“…This approach has the additional advantage that a series connection of single PV-cell can be easily achieved in order to realize higher output voltages [3]. The same group has also published another approach for the integration of a CIGS cell (CIGS: copper indium gallium arsenide) [4]. This type of PV-cell is thought to be more efficient as compared to a-Si:H cells, but requires special deposition techniques and materials not available in typical semiconductor fabrication.…”
