Abstract

A review of sensitization of TiO2 by supramols. contg. zinc porphyrins and ruthenium-polypyridyl complexes in solar cells. Conversion of sunlight to elec. power is being examd. through the use of new-generation photovoltaic cells. For such devices, anchored ruthenium polypyridyl complexes with suitable substituents on meso-porous TiO2 have been tested and are a cost-effective alternative to conventional solid-state devices. Photoinduced charge-carrier generation at the heterojunction has become very efficient after the incorporation of metalloporphyrins.

Organic solar cell

An organic solar cell (OSC) or plastic solar cell is a type of photovoltaic that uses organic electronics, a branch of electronics that deals with conductive organic polymers or small organic molecules, for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect. Most organic photovoltaic cells are polymer solar cells. The molecules used in organic solar cells are solution-processable at high throughput and are cheap, resulting in low production costs to fabricate a large volume.

Solar cell

A solar cell, or photovoltaic cell, is an electronic device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as solar panels.

Timeline of solar cells

In the 19th century, it was observed that the sunlight striking certain materials generates detectable electric current – the photoelectric effect. This discovery laid the foundation for solar cells. Solar cells have gone on to be used in many applications. They have historically been used in situations where electrical power from the grid was unavailable. As the invention was brought out it made solar cells as a prominent utilization for power generation for satellites.
