Solar-Tectic LLC presents breakthrough perovskite/crystalline silicon thin-film tandem solar cell technology at Energy conference in Inverness, Scotland

Solar-Tectic LLC ("ST") presented a paper today at the "Fifth International Symposium on Energy Challenges and Mechanics (ECM5) - working on small scales" in Inverness, Scotland, making public for the first time details of its breakthrough technology for highly efficient and inexpensive solar cells.

 The paper, titled "High efficiency perovskite/crystalline silicon thin-film tandem solar cell from a highly textured MgO[111] buffered glass substrate: a proposal" has been submitted for publication in the peer reviewed "Journal of Energy Challenges and Mechanics".

Recently perovskite materials have gained much attention as a solution to the longstanding problem of solar cell efficiency, and while there have been many reports of perovskite/silicon tandem solar cells, remarkably there have been none on perovskite/thin-film silicon.  Crystalline thin-film silicon promises to be less expensive than silicon wafer technology due to low temperature processing and less material use.

Importantly, the entire process is non-toxic since tin (Sn) is used in the perovskite material, rather than lead (Pb). The technology is the very first of its kind to be published and patents have been filed for world-wide protection.

In May, 2016 Solar-Tectic LLC was granted a patent for a related technology, a hybrid inorganic/polymer thin-film solar cell (see US patent 9.349,995 B2 for details).

About Solar-Tectic LLC ("ST"):  Solar-Tectic LLC is a thin-film specialist with patented technology primary focused on developing highly textured, single crystal semiconductor films on glass or other inexpensive substrates.  The company has a wide portfolio of technologies and IP towards this end, based primarily on inventions by the late Dr. Praveen Chaudhari, renowned materials physicist and recipient of a US National Medal of Technology and Innovation (1995). All the technologies being developed are consistent with Solar-Tectic's mission to provide cleaner and more accessible energy to fight climate change and poverty rampant in the world today.  Solar-Tectic LLC's primary focus in this regard is solar cells, but also extends to LEDs, and superconducting wires.  Recently several papers were published in a peer reviewed journal reporting advances in R&D.
