6 FAQs about [Photovoltaic cells are smooth]

Are flexible solar cells useful for building integrated photovoltaics?

Instructiveness for building integrated photovoltaics and wearable photovoltaics. Flexible solar cells are widely researched for their potential usage in photovoltaics integrated into buildings, cars, unmanned arial vehicle and wearable electronics.

How do photovoltaic cells work?

Photovoltaic cells generate a voltage between their front and back sides. Both sides must be electrically contacted. At least for the front side (and for bifacial cells, the back side as well), this must be done in such a way that the light input is reduced as little as possible.

Do photovoltaic cells need cooling?

Effective cooling of the photovoltaic cells is also required to avoid a substantial reduction of conversion efficiency. So far, efficiencies of around 15% have been achieved.

What is a special photovoltaic cell?

Very special cells based on SiGe or quantum dots can then be used. A small niche application for special photovoltaic cells is the use in thermophotovoltaic generators, where instead of sunlight one uses thermal radiation from a hot body, typically with a temperature between 1000 °C and 2000 °C.
