Are 'nano photovoltaics' the future of solar PV cells?

The newer devices for photovoltaic power generation are considered in the fourth generation of solar PV cell technology, these devices often termed as “nano photovoltaics” can become the future of solar PV cells with high prospect.

Are solar PV cells based on thin films better than first generation?

The solar PV cells based on thin films are less expensive, thinner in size and flexible to particular extent in comparison to first generation solar PV cells. The light absorbing thickness that were 200–300 µm in first generation solar PV cells has found 10 µm in the second generation cells.

What is a photovoltaic cell (PV)?

Photovoltaic cells (PV) are tools used for the effective and sustainable conversion of the abundant and radiant light energy from the sun into electrical energy [4, 5, 6, 7, 8]. In its basic form, a PV is an interconnection of multiple solar cells aimed at achieving maximum energy output (see Figure 1).

What determines the VOC of solar PV cells?

The VOC of solar PV cells is generally determined by the difference in the quasi Fermi levels. In inorganic semiconducting materials, the electrons lose their potential energy and shift into a new energy level below conduction band when these electrons are photoexcited and move through a thermalization process.

What is a photovoltaic effect?

The photovoltaic effect is used by the photovoltaic cells (PV) to convert energy received from the solar radiation directly in to electrical energy .

Are solar photovoltaic cell output voltage and current related?

Through the above research and analysis, it is concluded that the output voltage, current, and photoelectric conversion rate of solar photovoltaic cells are closely related to the light intensity and the cell temperature.
