Modelling Various Solar Cells Materials Using Lorentzian-Drude Coefficients

Semiconductor Materials for Solar Cells

In most of today solar cells the absorption of photons, which results in the generation of the charge carriers, and the subsequent separation of the photo-generated charge carriers take place in semiconductor materials. Therefore, the semiconductor layers are the most important parts of a solar cell; they form the hart of the solar cell. There are a number of different semiconductor materials t...

Thin Film Solar Cells Using Earth-Abundant Materials

Hole-Transport Materials for Perovskite Solar Cells.

The pressure to move towards renewable energy has inspired researchers to look for ideas in photovoltaics that may lead to a major breakthrough. Recently the use of perovskites as a light harvester has lead to stunning progress. The power conversion efficiency of perovskite solar cells is now approaching parity (>22 %) with that of the established technology which took decades to reach this lev...

Dye-sensitized Solar Cells: Materials and Processes

The dye-sensitized solar cell (DSSC) has been proven to have a good chance to become a notable competitor for solar cells based on today technology of p-n junction. The principle of operation of DSSC solar cells in comparison with conventional semiconductor solar cells where light absorption and charge carrier transport are done by the semiconductor is different. In DSSC these two tasks are sep...

Perovskite solar cells: from materials to devices.

Perovskite solar cells based on organometal halide light absorbers have been considered a promising photovoltaic technology due to their superb power conversion efficiency (PCE) along with very low material costs. Since the first report on a long-term durable solid-state perovskite solar cell with a PCE of 9.7% in 2012, a PCE as high as 19.3% was demonstrated in 2014, and a certified PCE of 17....
