Digitization of a small game. The game is called "construction of a photovoltaic panel.".

The game is called "construction of a photovoltaic panel.". START OF THE GAME: A boy/character arrives at the photovoltaic construction office. The boy informs that he wants to learn how to make a solar panel. The owner of the office accepts and replies "I teach you by playing a game". GAME: The game consists of guessing the order of the layers, each time he guesses he is assigned a point. if he does not guess the owner of the office helps him and explains what layer it is and its function. At the end of the game, the solar panel must show itself built and show the points of the boy. OBJECTIVE OF THE GAME: show how to build a photovoltaic panel in English. PS. it must be only in English and not very professional. Structure of a photovoltaic cell, layer in order: 1. Metal grating on the sun exposed side: side exposed to the sun has worked purely to protect it. Metal grating takes its name from its composition: it is in fact a grid d is often made of metal. 2. Anti-reflective layer: In the sun exposed surface on the layer that collects the positive charges. Since it doesn’t reflect the light, it allows the use of the light that would otherwise be reflected and wasted. 3. Layer that collects the positive charges: It is located on the side exposed to the sun of the photovoltaic material, it is a layer with a majority of negative charges that attract positive charges made from the photons in the photovoltaic [login to view URL] layer that collects positive charges is a portion of material where a majority of set negative charges are located and mobile positive charges. The negative charges attract the positive charges made from the photons in the photovoltaic material. 4. Photovoltaic material: This is the core of a photovoltaic cell. This is where the absorbed light creates a pair of mobile negative and positive charges, available for the transfer of energy. In 90% of the photovoltaic cells, the photovoltaic cell is made out of silicon. A material that has a photovoltaic effect must have certain optical and microscopical characteristics: It must absorb visible light so it must not be transparent The energy of the absorbed photon must be enough to detach an electron from its atom and make it mobile inside the material It must be without imperfections in order to not hinder the motion of the loose charges Between the materials that have this characteristic we have: copper, indium and gallium, selenium, some carbon compounds, some Petroviskit materials, and of course silicon. 5. Layer that collects the negative charges: Located on the back of the photovoltaic material. It is a very thin layer with set positive charges, the negative charges from the photovoltaic layer are dragged towards this layer. This layer is made by inserting atoms of phosphorus and arsenic (less than 0.1%). It can be located on the side exposed to the sun or behind the photovoltaic cell. In our example, you can place it on the back. 6. Metal layer on the back of the solar cell: Metals are needed in order to bring electrons out of the photovoltaic cell in order to have a circulating current.
