The photovoltaic cells of the Science and Technology Innovation Board are too thin

Are thin-film solar cells the future of PV?

It is safe to assume that thin-film solar cells will play an increasing role in the future PV market. On the other hand, any newcomer to the production scene will, for obvious reasons, have a very hard time in displacing well-established materials and technologies, such as crystalline and amorphous silicon.

Why do large-area photovoltaic systems need high-efficiency solar cells?

Because the cost of photovoltaic systems is only partly determined by the cost of the solar cells, efficiency is a key driver to reduce the cost of solar energy, and therefore large-area photovoltaic systems require high-efficiency (>20%), low-cost solar cells.

Are perovskite solar cells the future of solar energy?

The U.S. Department of Energy’s (DOE’s) Solar Futures Study finds that new PV cell technologies are essential to compensate for the limits of silicon. Perovskite solar cells could be the high-efficiency PV technology the world needs to drive down solar PV costs aggressively.

What is a photovoltaic solar cell?

In 1893 the photovoltaic effect was reported leading to actual photovoltaic solar cells (PVScs) that can produce electricity from solar radiation taking into consideration the Schockly-Queisser efficiency limitations.

What are thin-film perovskite solar cells?

Thin-film perovskite solar cellsuse a single layer of perovskite material to convert light to usable energy. Figure 1 shows thin-film perovskite solar cells developed by the Korea Research Institute of Chemical Technology that are about 200 times thinner than traditional silicon solar cells.

Are perovskite solar cells better than silicon solar cells?

Perovskite solar cells are far from perfect, though. They are very sensitive to oxygen, moisture, and heat, making them less durable than silicon solar cells. Scientists have yet to demonstrate the ability to make high-efficiency perovskite solar cells in a large-area format.
