Researchers in the School of Electrical, Computer and Energy Engineering contributed to findings recently published in two papers in the scientific journal Joule. Alone, each paper details significant breakthroughs in solar cell research, but together they spotlight innovations that overcome two major hurdles, fabrication and deployment. The team’s discoveries could result in solar cells that are more efficient than today’s modules and less expensive to produce.

Predicted Power Output of Silicon-Based Bifacial Tandem Photovoltaic Systems

In the first article published on January 2, the research group highlights their results from bifacial tandem photovoltaic systems models. The study showed unoptimized tandem solar cells produce more energy than their optimized monofacial counter-parts.

(A) Bifacial single-junction c-Si cell. (B) Monofacial perovskite/c-Si tandem. (C) Bifacial perovskite/c-Si tandem.

Blade-Coated Perovskites on Textured Silicon for 26%-Efficient Monolithic Perovskite/Silicon Tandem Solar Cells

In a separate article published later in January, the team describes their unique approach to produce tandem solar cells using silicon and perovskite. The result was a high-efficiency cell that can be manufactured at a lower cost.

A new architecture of monolithic perovskite/silicon tandem device is proposed based on double-side-textured silicon cells with sub-micrometer pyramids.
