In order to understand the transmitted light beam, the technician uses a beam profiler using a camera, Laser pointer or non-contact Rayleigh scattering. These are NIST traceable devices that can measure power density curves according to known standards. In short, they can help technicians map and understand the transmitted beam, so that they can use real-time real-time data for analysis based on industry standards.
Generally speaking, it is wise to wear support shoes. Because unless you live in a big city like New York, the pace of the rest of the world will greatly exceed the typical pace of the United States. This is especially important if you plan to walk a full day after travelling to and from the hotel, train station, and taxi stand, and stay in the hospital for a full day. Pack up your shoes and prepare for meetings and presentations, laser engraver, running shoes have become the clinical norm. The ultimate goal of preparation through R2R processing is of course to have a product that can be integrated and commercialized.
As mentioned earlier, OPV may be the most mature technology in terms of R2R processing, but so far, the commercialization process has not really shown its potential. The Konarka solar bag is the only real product so far that allows users to charge small devices such as mobile phones. However, some non-commercial demonstrations of integrating this technology have been reported. One of the earliest examples is the "sun hat" that can be used to power small radios. More than 2,000 130 cm2 modules were produced for this event using only screen printing (Krebs, Jørgensen, etc., 2009). Another example is part of the "African Lighting Project", which uses solar cell modules (20×25 cm2) to charge small reading lights with rechargeable batteries (Krebs, Nielsen, Fyenbo, Wadstrøm and Pedersen, 2010). This concept was later used to make an OE-A flashlight demonstrator the size of 10,000 credit cards (Krebs et al., 2011). Recently, Espinosa et al. A small laser pointer similar in size to the OE-A flashlight is prepared to show the latest progress of OPV technology. These laser pointers use ITO-free OPV modules to charge lithium-ion polymer batteries (Espinosa et al., 2013).
The hybrid system has sensors that can measure the profile, power and position of the blue laser pointer beam. They can accurately display the power density distribution map of the beam and its position and consistency.
