Abstract: The open-circuit voltage ( V OC ) of polycrystalline state-of-the-art, arsenic-doped CdSeTe/CdTe solar cells has reached 917 mV, and the record cell efficiency has been gradually increasing.
Cadmium telluride solar cells are the most widely used thin-film solar technology in the world, but their performance still has significant room for improvement. A new approach could now boost their open-circuit voltage by 13% and enhance overall efficiency. What are CdTe photovoltaics and how do they work?
PV solar cells based on CdTe represent the largest segment of commercial thin-film module production worldwide. Recent improvements have matched the efficiency of multicrystalline silicon while maintaining cost leadership.
Conclusions and outlook Herein we have reviewed the developments in the cell technology that has enabled CdTe solar modules to emerge as the highest- production thin film photovoltaic technology.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
For CdTe, which has a bandgap of 1.5 eV, the gap is larger; for polycrystalline samples, the open-circuit voltage of solar cells with the record efficiency is below 900 mV, …
