Thin film solar photoelectric conversion rate, the theoretical value of crystalline silicon cells and thin-film battery are 30%, thin film solar cell photoelectric conversion rate generally only equivalent to half of the rate of conversion of crystalline silicon cells, but some companies, such as China Hina new product photoelectric conversion rate has reached 16%. Before the University of Mainz, Germany issued a communique, thin film solar laboratory photoelectric conversion rate exceeded 20% of the record. According to the Associated Press, October 31, Stanford University has developed the first carbon thin film solar cells, which broke through the traditional thin-film Solar water heaters solar cells rely on the conductive metal and indium tin oxide, and lead to large-scale application prices have rocketed.Carbon Earth is abundant, low cost, we can be optimistic forecast in the near future, the cost of thin-film solar cell power generation and thermal power, and even hydroelectric compete.
Thin-film solar power generation applications. Large area, thin-film solar insurmountable constraints. Large-scale application of the two areas through policy guidance, thin film photovoltaic solar greenhouses application, plant photosynthesis using mainly the wavelength of 610nm ~~ 720nm (peak to 660nm) red-orange light, thin-film Solar water heatings solar cell maximum absorption peaks at 400 ~ 600nm theoretically the maximum absorption peak of the thin film solar cell with the plant photosynthesis absorption peak does not conflict, and the thin film solar cell can absorb ultraviolet burns plants. So it can be a combination of thin-film solar power generation facility agriculture, an area of an acre of greenhouses, in theory, power generation will reach 60,000 degrees a year. Facility Agriculture in China area of more than 300 million hectares, in which the high-grade glass greenhouse, building area of more than 200 million hectares of plastic greenhouses. If all two million hectares of facility agriculture transformed into photovoltaic greenhouses, annual generation capacity will reach 1.8 trillion kWh, equivalent to 40% of national electricity consumption in 2011. BIPV development. BIPV technology is the integration of solar power products to building technology, eco-city, green city, low-carbon city, regardless of which concepts are inseparable from the large-scale application of BIPV. In addition, solar power in the city is closest to the load centers, which greatly enhanced the efficiency of the actual use of photovoltaic power generation, in addition to building integrated features, the actual investment costs considerably lower than in the field of photovoltaic power plants, investment and energy efficiencyhas a huge advantage, is the inevitable choice for future urban development.
