I'm the CEO of the National Center for Women and Information Technology or NCWIT and with me is Larry Nelson, w3w3.com Internet radio. Larry Nelson: Yes. Lucy: And we are very happy to be doing one in a series of interviews with women who have started IT companies and we love this series because there is so much wisdom with these entrepreneurs that everybody can benefit from. Larry: Yes, it's very exciting and we get a tremendous amount of business leaders, parents, all with different ages of people who tuned in and listen to this and we are very happy because we know that we need a lot of encouragement in this area. Lucy: Absolutely and very excited about today's interview. We are interviewing an entrepreneur who is helping the world solve our energy problems. We all know energy is a very important topic, very hot topic and the person we are interviewing today is a very impressive one. She has very impressive technical credentials with a PhD from MIT and also post doctoral work at Los Alamos laboratory. So, very, very well credentialed to take on the energy problems of the world. So, just to get right to it. We are interviewing Marcie Black who is the CTO and co-founder of Bandgap Engineering. And we are going to let her tell us a little bit about what the company does but in brief, they pioneered the development of highly tunable and inexpensive methods for nano structuring silicone and they are applying that technology to high efficiency solar cells. So, Marcie, first of all welcome and why don't you tell our listeners what this technology is all about. Marcie Black: Lucy and Larry, thank you for having me. It is a pleasure to be here. So, Bandgap Engineering is reducing the cost of solar electricity and the reason why we are doing that is there are a lot of trade-offs in producing electricity and by moving to renewable energy source, we can lessen some of those trade-offs. And solar is the only renewable energy source that has the potential of being or dominant energy supply. So, there's a couple of ways to reduce the price of solar electricity so that it is cost competitive with conventional sources. One of the ways is by reducing the cost of processing the semi conductors. But another way is increasing the efficiency of the solar cell and by increasing efficiency means that you can get more power over the same area of the solar cell. So, what Bandgap Engineering is doing is increasing the efficiency of the solar cell while keeping the cost per area constant. And that effectively will bring down the cost of electricity from solar energy making it cost competitive with other conventional energy sources. And as you mentioned the way that we are increasing the efficiency is by nano engineering silicone so that it's a better converter of energy from optical energy to electrical energy. Lucy: Wow. Larry: Yeah. Lucy: Now, see, I just write softwares. I'm pretty impressed. Larry: No small thing. Lucy: It is very important and it is a young company, isn't it Marcie? Marcie: Yeah, we are about three years old. Lucy: Awesome. So, how did you first get into technology? You obviously love technology and I think our listeners would be very curious to know how you first became interested in it and besides, the nano technology which you are using today, other technology that you see are especially important. Marcie: Yeah like many engineers. I've emerged from very early on. So, I remember when I was very young, my father who was also an engineer would take me to the basement and we'll build electronic circuits and radios and do all kind of cool, crazy stuff in the basement. But when I got old
