The Hybrid Tandem Technology
Uriel Solar is an R&D business, developing a disruptive technology we call the ‘hybrid tandem’ solar cell, which we expect to achieve a practical panel efficiency of 30% at a production cost per watt comparable to or below current commodity silicon or thin film cost. This efficiency level is unheard of in the commercially competitive solar market.
This hybrid tandem technology utilizes a crystalline silicon bottom solar cell combined with a CdTe-based alloy top solar cell. While single junction solar cells, such as silicon and CdTe, have theoretical maximum efficiencies of 28% and 30%, respectively, the hybrid tandem solar cell has a theoretical maximum efficiency of 40%, providing considerable headroom for performance improvement as the technology penetrates the market.
Growth of CdTe-based alloys requires a high level of expertise, which is essentially limited to a small segment of experts who work in the area of high-end, state-of-the-art CdTe alloy focal plane arrays for space and military applications. The Uriel team includes some of the most qualified professionals in this field.
With 6 patents and multiple patents pending on this next generation technology, Uriel Solar will redefine commercial solar energy generation.
