- The invention enhances the efficiency of silicon photovoltaic solar cells by facilitating the downshifting of wavelengths so that crystalline silicon can absorb wavelengths in the range suitable for conversion. This is achieved by coating silicon with specific films of the order of nanometers thickness.
- Power conversion efficiencies of 10% or more can be achieved for a small percentage increase in the cost of solar cells. The thin film also increases the life of a solar cell. A layer of polydimethylsiloxane applied over the perovskite quantum dots will increase its usable life.
- This invention is significant because 85 -90% of solar cells in today’s market are made of silicon solar cells. Crystalline Silicon (c-Si) solar technology is the most prominent form of solar cell technology in the U.S. residential market, yet the efficiency of these specific solar cells has plateaued over the last 15 years.
