Novel Materials and Processes for Photovoltaic Technology

Time Domain Simulation of Novel Photovoltaic Materials

Chung, Haejun MSECE, Purdue University, December 2013. Time Domain Simulation With Novel Photovoltaic Materials. Major Professor: Peter Bermel. Thin-film silicon-based solar cells have operated far from the Shockley-Queisser limit in all experiments to date. Novel light-trapping structures, however, may help address this limitation. Finite-difference time domain simulation methods offer the pot...

Chapter 2 . Novel Processes and Materials for Infrared Nonlinear Optics

Optical systems such as signal processors, limiters, spatial light modulators, and optical computers require large and fast optical nonlinearities. Although free carrier-induced nonlinearities in semiconductors have the picosecond speeds required for use in many applications, they were considered too weak to be practical for optical systems applications. In our work, we have demonstrated that t...

Novel technology for laser precision microfabrication of hard materials

Hybrid laser processing for precision microfabrication of hard materials, in which the interaction of a conventional pulsed laser beam and another medium on the material surface leads to effective ablation, is reviewed. The main role of the medium is to produce strong absorption of the nanosecond laser beam by the materials. Simultaneous irradiation with the ultraviolet (UV) laser beam and the ...

A Novel Photovoltaic Powered Reverse Osmosis with Improved Productivity of Reverse Osmosis and Photovoltaic Panel

With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...
