About Us

The Semiconductor Thin Film and Plasma Processing Lab was set up in 1995 to carry out fundamental and applied research in the area of semiconductor thin films and devices, surface modification and plasma processing of various materials. Our main aim was to develop new processes and materials in thin film form, capable for a variety of applications ranging from solar cells, thin film light emitting devices (TFLEDs), microelectronic devices, sensors and actuators (MEMS). In the last twenty years we have expanded our scope of research from silicon based thin films to silicon nanostructures, boron carbide and also graphene.

The work carried out till now has long reaching implications in technology and has established the applicability of the HWCVD process in the area of photovoltaics, nanotechnology, MEMS and back end processing in microelectronics industry. Major research contributions are

  • 13% efficient silicon heterojunction solar cell
  • 8.8% efficient a-Si:H p-i-n thin film solar cell on glass
  • 6% efficient a-Si:H p-i-n solar on flexible PEN and steel substrate
  • Silicon nanowire based supercapacitor
  • Boron carbide neutron detectors
  • Microcrystalline silicon based piezo resistive pressure sensors
