Solar Power From Patented Crystals Imitating A Leaf

Cryscade Solar, Ltd. was founded in 2006 by Dr. Pavel Lazarev to develop Donor-Bridge-Acceptor (DBA) photovoltaic chemistry. The Company assembled a world-class R&D team, which has successfully synthesized DBA molecules that self assemble into nano-crystalline PV stacks. Cryscade was recently granted foundational intellectual property for its homeotropic crystalline PV materials.

Cryscade Has the Potential to Break the Solar Cost-Performance Barrier

Cryscade’s Donor-Bridge-Acceptor (DBA) is the only technology able to significantly reduce recombination, surpass the Shockley-Queisser limit for conventional semiconductor PV and produce a 30+% efficient single junction photovoltaic cell. Cryscade’s technology can fundamentally change the cost and performance of solar PV energy.

Electrons and Holes are Separated and Conducted in Separate Crystalline Columns

Cryscade is developing a PV system that uses homeotropic (vertical) self-assembly of specialized perylene-based molecules to create a DBA structure that 1) absorbs light, 2) separates the electron from its electron-hole and 3) conducts them in separate crystalline columns to the anode and cathode. Cryscade has already developed and tested this DBA technology.

DBA Charge Separation Eliminates Recombination in the Semiconductor

A conventional PV device loses ~16% of its efficiency, out of a 49% theoretical limit, due to electron-hole recombination. Cryscade has demonstrated that these recombination losses can be reduced by 10,000 times through charge separation and conduction of electrons and holes through separate columns of homeotropically aligned DBA molecule stacks. No other PV technology can reduce recombination to this extent.
