Earlier this month, NJIT formalized an agreement with Chinese partners that will advance the university’s research on thin-film solar cells, an alternative energy technology with the potential to make buildings and other infrastructure substantially more energy-efficient.

The CNBM Center has already developed important insights into the physics of the photoelectric behavior of these materials, which suggests that new manufacturing conditions could produce much higher cell efficiencies.
“Cadmium telluride is a promising photovoltaic material, but to date, with the exception of a single company, it has been difficult to produce and deploy on a manufacturing scale,” said
With its new funding, the solar team is building a machine, for example, that will permit manufacturers to deposit thin layers of a transparent conductive material such as zinc oxide on a photovoltaic plate without oxidizing the surface of the source metal in the process.
“Conventional technology performs reactive sputtering to form metal oxides for thin-film solar cells, transistors, and sensors, but this process is notoriously difficult to control,” Delahoy said, adding, “Process control is a big challenge in thin-film production. We are trying to come up with better manufacturing methods.”
The research team is also building sensitive equipment that will allow manufacturers to better detect defects in semiconductors.
CNBM is eager to speed development of inexpensive power production that can be seamlessly incorporated into a range of building materials.
“If just the rooftops of the world’s commercial buildings were equipped with current generation solar panels, it would satisfy ten percent of the global energy need. Imagine if every surface of civil infrastructure and private housing could be generating power,” said
