Course Introduction

Introduction to solar cells In this course you will be able to understand the basic concepts of solar cells, why they work and what they can provide. We will take you through the fundamental physics of solar cells, their characteristics and how to work with them. We will also cover the battery system in this course and how solar cells are connected to the grid. We will take you through the different types of solar cells, the different types of cells and the different types of cells used in different applications. You will learn how to use the different types of cells and how to choose the type that is right for you. You will also learn how to find the correct kind for you. This is all at a very basic level, so you will not get all the details that are needed in the course. You will need to have equivalent level of English as your target language so you can understand most of what is being taught. You will also need to have some basic math skills, especially in the area of ratio theory. The course is designed for intermediate-level students, but we expect most of what is taught will be of interest to students of more advanced levels. We hope you have a great time in this course and will see you in our next one!Introduction to solar cells Basics of semiconductor materials Semiconductor properties Semiconductor production Introduction to Spacecraft Dynamics This course introduces the basic concepts and technologies

Theory of solar cells This approach should only be used for comparing solar cells with comparable layout. For instance, a comparison between primarily quadratical solar cells like typical crystalline silicon solar cells and narrow but long solar cells like typical thin film solar cells can lead to wrong assumptions caused by the different kinds of current paths and therefore the influence of, for instance, a distributed series resistance contribution to "r". Macro-architecture of the solar cells could result in different surface areas being placed in any fixed volume - particularly for thin film solar cells and flexible solar cells which may allow for highly convoluted folded structures. If volume is the binding constraint, then efficiency density based on surface area may be of less relevance.
Timeline of solar cells The timeline of solar cells begins in the 19th century when it is observed that the presence of sunlight is capable of generating usable electrical energy. 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.
Tin based perovskite solar cells Tin-based perovskite solar cells are still in the research phase and there are relatively few publications about them, compared to their counterpart, lead-based perovskite solar cells. This is mainly due to the instability of the 2+ oxidation state of tin (Sn) in methylammonium tin iodide (CHNHSnI), which can be easily oxidized to the more stable Sn, leading to a process called self doping, where the Sn acts as a p-dopant leading to the reduction in the solar cell efficiency.
Tin based perovskite solar cells The main advantage of tin-based perovskite solar cells that they are lead-free. There are environmental concerns with using lead-based perovskite solar cells in large-scale applications; one such concern is that since the material is soluble in water, and lead is highly toxic, any contamination from damaged solar cells could cause major health and environmental problems.
Theory of solar cells 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 theoretical studies are of practical use because they predict the fundamental limits of solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
Solar vehicle Solar cars depend on PV cells to convert sunlight into electricity to drive electric motors. Unlike solar thermal energy which converts solar energy to heat, PV cells directly convert sunlight into electricity.
Inkjet solar cell In traditional solar cells the material that holds the photovoltaic material generally costs more than the material itself. With inkjet printing it is possible to print solar cells on paper. This will allow solar cells to be much cheaper and be placed almost anywhere. Paper thin solar cells or eventually direct 3D printing will allow to create solar cells on blinds, in windows, in curtains, and almost anywhere in the home. This is very promising and could be the future of solar power.
Solar vehicle Solar Electrical Vehicles is adding convex solar cells to the roof of hybrid electric vehicles.
Theory of solar cells Temperature affects the characteristic equation in two ways: directly, via "T" in the exponential term, and indirectly via its effect on "I" (strictly speaking, temperature affects all of the terms, but these two far more significantly than the others). While increasing "T" reduces the magnitude of the exponent in the characteristic equation, the value of "I" increases exponentially with "T". The net effect is to reduce "V" (the open-circuit voltage) linearly with increasing temperature. The magnitude of this reduction is inversely proportional to "V"; that is, cells with higher values of "V" suffer smaller reductions in voltage with increasing temperature. For most crystalline silicon solar cells the change in "V" with temperature is about -0.50%/°C, though the rate for the highest-efficiency crystalline silicon cells is around -0.35%/°C. By way of comparison, the rate for amorphous silicon solar cells is -0.20%/°C to -0.30%/°C, depending on how the cell is made.
Organic solar cell Polymer solar cells have yet to commercially compete with silicon solar cells and other thin-film cells. The present efficiency of polymer solar cells lies near 10%, well below silicon cells. Polymer solar cells also suffer from environmental degradation, lacking effective protective coatings.
Polymer-fullerene bulk heterojunction solar cells Polymer-fullerene bulk heterojunction solar cells are a type of solar cell researched in academic laboratories. Photovoltaic cells featuring a polymeric blend of organics have shown promise in a field largely dominated by inorganic (e.g. silicon) solar cells. Specifically, fullerene derivatives act as electron acceptors for donor materials like P3HT (poly-3-hexyl thiophene-2,5-diyl), creating a polymer-fullerene based photovoltaic cell.

Theory of solar cells The overall effect of temperature on cell efficiency can be computed using these factors in combination with the characteristic equation. However, since the change in voltage is much stronger than the change in current, the overall effect on efficiency tends to be similar to that on voltage. Most crystalline silicon solar cells decline in efficiency by 0.50%/°C and most amorphous cells decline by 0.15-0.25%/°C. The figure above shows I-V curves that might typically be seen for a crystalline silicon solar cell at various temperatures.
Solar car Some solar cars use gallium arsenide solar cells, with efficiencies around thirty percent. Other solar cars use silicon solar cells, with efficiencies around twenty percent.
Copper indium gallium selenide solar cells In the highly competitive PV industry, pressure increased on CIGS manufacturers, leading to the bankruptcy of several companies, as prices for conventional silicon cells declined rapidly in recent years. However, CIGS solar cells have become as efficient as multicrystalline silicon cells—the most common type of solar cells. CIGS and CdTe-PV remain the only two commercially successful thin-film technologies in a globally fast-growing PV market.
Theory of solar cells In thick solar cells there is very little electric field in the active region outside the space charge zone, so the dominant mode of charge carrier separation is diffusion. In these cells the diffusion length of minority carriers (the length that photo-generated carriers can travel before they recombine) must be large compared to the cell thickness. In thin film cells (such as amorphous silicon), the diffusion length of minority carriers is usually very short due to the existence of defects, and the dominant charge separation is therefore drift, driven by the electrostatic field of the junction, which extends to the whole thickness of the cell.
Solar cell Assemblies of solar cells are used to make solar modules that generate electrical power from sunlight, as distinguished from a "solar thermal module" or "solar hot water panel". A solar array generates solar power using solar energy.
