New CZTS Solar Cell Efficiency Record

Originally published on Solar Love. Solar Frontier, a Japan-based thin-film solar technology company, has reportedly broken the CZTS solar cell efficiency record, in partnership with IBM and TOK. The efficiency record was set on a solar cell 0.42 square centimeters in size. The new record is 12.6% efficiency. The previous record of 11.1% was held … [continued]

CZTSe Solar Cells Achieve 9.7% Efficiency

This article was originally published on CleanTechnica sister site Green Building Elements. A Copper Zinc Tin Selenide (CZTSe) solar cell technology has achieved an efficiency of 9.7% and an open-circuit voltage of 0.41 volts, a bit less than the 0.5 volts that most silicon-based solar cells achieve. (Solar cells are … [continued]

University of Utah metallurgical engineers Prashant Sarswat and Michael Free used an old office microwave oven to produce a nanocrystal semiconductor named CZTS that is made from cheaper, less toxic materials than other semiconductors and holds promise for more efficient solar power cells and lighting by LEDs, or light-emitting diodes, as well as sensors for medical tests and systems to convert waste heat to electricity.

Solar Cell Material Created From Microwave Oven

Another fun solar science story, this one via the University of Utah: University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and … [continued]
