As solar cell technology matures from an implementation standpoint, newer challenges are emerging to render the technology as economical as Silicon CMOS.
There is an intense effort in the field to reduce the per module cost, largely by achieving a thinner substrate for light trapping in PV modules.
Photovoltaics research in the Banerjee Lab focuses on flexible solar cells based on our unique kerfless exfoliation technique in creating ultrathin silicon foils. Simultaneously,
we are also engaged in exploring novel material systems for their PV characteristics and integration into the mature PV technology.
