5、提高家居或办公室的太阳能电能的使用。今年年初，三菱公司在对光伏技术严格调查研究的基础上研制出一块太阳能电池板，它的最高光电转化率可以达到18.6%。这种表面无涂层的太阳能电池板去除了导线并允许扩充反射的太阳光线，从而提高了效率，同时也保护了环境。三菱公司也针对它们的太阳能电池板研制改进出用于扩大光线吸收区域的精巧的栅极，这些电池板的背面的结构设计也被改进。抗反射镜涂层用于减少组件的太阳能反射，同时精妙的电流条设计协调减小阻力。这种太阳能板使用无铈的高透明的玻璃以及具有较强反射能力的底面膜，使反射功率加快到90%。三菱公司的太阳能板非常的先进，而且凭借它们的可靠性和耐久性被许多用户所依赖和认可。

Photovoltaic cells are generally made from modified silicon, or other semi conductive materials, that absorb and convert sunlight into electricity. Photovoltaic cells are long lasting (the first PV system e

But most solar professionals agree that a system should last at least 25 30 years. Types of Solar CellsThere are three basic types of PV modules: monocrystal

11、line, polycrystalline, and thin-film. All modules work well though monocrystalline cells often yield the greatest efficiencies. Thin-film technology typically costs less and its efficiency is ever improving as demand for solar panels grow. A growing variety of manufacturers and models are available

Solar Panels vs Building Integrated Photovoltaic Products (BIPV)Solar panels are flat panels of photovoltaic arrays mounted on a roof or a pole to capture the suns rays. They are the traditional arrays used to catch energy from

19、 to three of the most basic concerns people have about electricity use such are cost-efficiency, environmental protection, and lower electric bills. While most solar panels of today generally answer these concerns, Mitsubishi Electric tries to go a little further through their continuing research fo

Removing lead and allowing expanded light reflection goes for improved efficiency as well as environmental preservation with the solder-coatingless cells.Fine grid electrodes to expand the light-receiving area were also developed by Mitsubishi for their solar panels while their back surface field

22、structure was improved. To lessen the reflection of sunlight from the module, anti-reflective coating was also used as well as a unique bus bar design was integrated to reduce resistance. The solar panels also used high transmittance glass that are cerium-free, and a high reflectance back film which

23、 accelerates reflection power to 90 percent.Mitsubishi solar panels were also developed and mostly relied on by many users for their reliability and durability. Requiring little or no maintenance, these solar modules have guaranteed use of twenty years or more. Many owners of houses and buildings ha

To reduce the stress on tab

26、wiring, straight tabs are used; while to avoid reduction of electric when dust begins to thicken on the module corners, increased between the module framed and the bus bar is observed; and to prevent corrosion, anodized aluminum frames are used with clear coating.With the continuing research and tec

With the flexibility, low maintenance, reliability, and cost-efficiency that these solar energy tools afford people, it is expected that more

Building owners who are looking for ways to cut down on their electrical expenses have adopted this alternative energy approach with some even integrating the panels design with their own building, rather enhancing or making th

Other manufacturers are also accommodating homeowners who wish to use these as well by following the contour or roofing designs of the houses with their roof-mounted solar panels.Mitsubishi solar panels are not far behind with these modern innovations and design adaptation. With the proper consultation and choice among their line of flexible solar panels, having these PV modules in more homes and buildings at a greater number should not be impossible. . .此处忽略！8
