84 THE PHYSICS OF THE SOLAR CELL Figure 3.2 The radiation spectrum for a black body at 5780K, an AM0 spectrum, and an AM1.5 global spectrum The basic physical principles underlying the operation of solar cells are the subject of this chapter. First, a brief review of the fundamental properties of semiconductors is given that include Solar cells The semiconductor devices through which sunlight is directly converted into electricity are called solar cells or photovoltaic cells. Solar cells are thin wafers made from silicon. Electrons in the silicon gain energy from the sunlight to create a voltage The solar cells produce electricity by converting the photons of light into the electrons, the solar cells are used to power anything from the small electronics such as the calculators and the road signs up to the homes, the satellites, the military applications, and the large commercial businesses This current, along with the cells voltage gives power (wattage) that the solar cell can produce. As we see from the diagram there are three important layers for energy conversion in the solar cell. The first one is the top junction layer (made of N-type semi-conductors)
The solar cell is an important candidate for an alternative terrestrial energy source because it can convert sunlight directly to electricity with good conversion efficiency, can provide nearly permanent power at low operating cost, and is virtually non-polluting. Solar cell also called as photovoltaic cell and are building blocks of solar panels The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device The Solar Cell• The most common type of solar cells are Photovoltaic Cells (PV cells)• Converts sunlight directly into electricity• Cells are made of a semiconductor material (eg. silicon)• Light strikes the PV cell, and a certain portion is absorbed• The light energy (in the form of photons) knocks electrons loose, allowing them to flow freely, forming a current• Metal contacts on the top and bottom of PV cell draws off the current to use externally as powe

Abstract III-V monolithic multi‐junction (MJ) solar cells reach efficiencies exceeding 30% (AM 1.5 global) and have applications in space and in terrestrial concentrator systems. The subcells of monolithic MJ cells are not accessible separately, which presents a challenge to measurement systems and procedures 3A molecular sieve layer was used as dehydration and electronic-insulation layer on the TiO 2 electrode of dye-sensitized solar cells. This layer diminished the effect of water in electrolyte efficiently and enhanced the performance of cells. The conversion efficiency increased from 9.58% to 10.2%. The good moisture resistance of cells was attributed to the three-dimensional interconnecting.
