Hello, Dear all, I will be writing a scientific "review" on a topic relating to electronic materials science. I have some candidates and open to suggestions, Please help me pick a promising topic which doesn't require diving in deep to be understood. My candidates are: - Photovoltaic Solar Collector - A nano-electronic device - Bio-Baterries - Organic LEDS/Transistors - Bio-fuel Please help...thanks. Ok- now i am 60% convinced to write on the "photovoltaic solar collectors" , what do you think? Can you direct me where to look for info? and is this a promising topic for a scientific review ?
