The operation of a photovoltaic (PV) cell requires 3 basic attributes:
The absorption of light, generating either electron-hole pairs or excitons.
The separation of charge carriers of opposite types.
The separate extraction of those carriers to an external circuit.
In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.Characteristic of Mono 156X156MM2 Solar Cells

Adaptive cells change their absorption/reflection characteristics depending to respond to environmental conditions. An adaptive material responds to the intensity and angle of incident light. At the part of the cell where the light is most intense, the cell surface changes from reflective to adaptive, allowing the light to penetrate the cell. The other parts of the cell remain reflective increasing the retention of the absorbed light within the cell.[67]
In 2014 a system that combined an adaptive surface with a glass substrate that redirect the absorbed to a light absorber on the edges of the sheet. The system also included an array of fixed lenses/mirrors to concentrate light onto the adaptive surface. As the day continues, the concentrated light moves along the surface of the cell. That surface switches from reflective to adaptive when the light is most concentrated and back to reflective after the light moves along

- Q: Can solar cells be used for outdoor lighting?
- Yes, solar cells can be used for outdoor lighting. Solar-powered lights utilize solar cells to convert sunlight into electricity which is stored in batteries during the day. This stored energy is then used to power the lights during the night, making them a sustainable and environmentally-friendly option for outdoor lighting.
- Q: How do solar cells perform in regions with high levels of salt spray and corrosive environments?
- Solar cells may experience degradation in regions with high levels of salt spray and corrosive environments. The salt particles and corrosive elements can cause the deterioration of the cell's components, such as the protective coatings and metal contacts. This can result in reduced efficiency and lifespan of the solar cells. However, advancements in materials and designs have been made to improve their resistance to corrosion, allowing solar cells to perform relatively well in such challenging environments.
- Q: How do solar cells perform in areas with high levels of water pollution?
- Solar cells can be adversely affected by high levels of water pollution. Water pollution can reduce the efficiency of solar cells by blocking sunlight and reducing the amount of light that reaches the surface of the cells. Additionally, pollutants in the water can corrode the surfaces of solar cells and damage their components, leading to a decrease in performance and lifespan. Therefore, in areas with high levels of water pollution, solar cells may not perform optimally and require more frequent maintenance and cleaning to ensure their effectiveness.
- Q: How many years should I spend in the solar cell industry to be a good solar cells sales person?
- A good solar cells should be equiped with both solar cells knowledge and good sales skills, and with very good people skills. Only in this way, you will be a good one.
- Q: What is the cost of solar cells?
- The cost of solar cells can vary depending on various factors such as the type of solar cell, its efficiency, manufacturing process, and market conditions. Generally, the cost has been declining over the years and continues to do so. As of 2021, the average cost of solar cells is around $0.20 to $0.50 per watt. However, it's essential to consider the overall system cost, including installation, inverters, and other components, to determine the total investment required for a solar energy system.
- Q: Can solar cells be used in agricultural farms?
- Yes, solar cells can be used in agricultural farms. They can be installed on rooftops or open fields to generate clean and renewable energy. This energy can be utilized to power various agricultural operations such as irrigation systems, lighting, and machinery. Additionally, solar cells can help farms become more self-sufficient and reduce their reliance on traditional energy sources, thereby contributing to sustainable farming practices.
- Q: How to explain to students how the solar cells are made?
- The solar cells are made in a high technology way, in which the silicon is a vital part.
- Q: Can solar cells be used in powering RVs and campers?
- Yes, solar cells can be used to power RVs and campers. Solar panels can be installed on the roof of the vehicle to capture sunlight and convert it into electrical energy, which can then be used to power various appliances and systems in the RV or camper. This provides a clean and sustainable source of power, especially when camping in remote areas where access to electricity may be limited.
- Q: Can solar cells be used in cloudy weather?
- Yes, solar cells can still be used in cloudy weather, although their efficiency may be reduced. Cloud cover will block some sunlight, causing a decrease in the amount of energy that can be generated by the solar cells. However, modern solar cell technology has improved to the point where even on cloudy days, some electricity can still be produced.
- Q: Can solar cells be used in museums?
- Yes, solar cells can be used in museums. They can be used to power various exhibits, displays, and lighting systems, providing a sustainable and renewable energy source. Additionally, solar cells can be integrated into the building's architecture, blending aesthetics with functionality, and reducing the museum's carbon footprint.
