pure sine wave inverters

With the increasingly serious energy and environmental problems, the increasing importance of the development and application of a variety of clean energy, in the use of solar energy is one of the most important means to solve energy shortage and environmental pollution, solar cells, pure sine wave inverter  energy utilization A very important aspect.

This application and development of the solar cell including the crystalline silicon (monocrystalline silicon, polycrystalline silicon, class monocrystalline) solar cell, an inorganic semiconductor thin film (amorphous silicon, CdTe, GaAs, CuInSe2) solar cell, the organic dye-sensitized solar cell and an organic solar cell, and so on. Battery current commercialization on the market is mainly inorganic material-based solar cell, but there are a problem of high cost, high energy-consuming process of preparation and purification of the photovoltaic material, the cell fabrication process is complicated.
The organic solar battery is a novel organic thin film solar cell can be considered as the third generation cells, pure sine wave inverter typical of the organic solar battery film sandwiched by a blend of conjugated polymers or small organic molecules to the body and a fullerene derivative receptor transparent ITO conductive glass cathode and the metal negative. Its structure is shown in Figure 1 and 2. The organic solar battery with preparation process is simple, low cost, light weight, and flexible devices such outstanding advantages can be prepared.
Small area devices laboratory reported the highest photoelectric conversion efficiency from less than 1% in 1995 to more than 9%. Before abroad have been a number of companies active in the organic solar cell industry, industry reports battery efficiency more than 10% (Mitsubishi Chemical, Japan and California Polytechnic University to develop), has begun the road of industrialization the Heliatek company reported battery efficiency up to 10.7%.
The B2912A of organic-based solar cell testing program  pure sine wave inverter Works of organic solar cells and solar cells based on inorganic materials similar to sunlight is incident from the side of the transparent electrode to the active layer, the active layer of photovoltaic materials absorb photons generate excitons (electron - hole pairs); exciton to the donor / receptor interface proliferation and migration;
proliferation and migration to the interface at the exciton under the role of the energy difference to / receptor electronic charge separation occurs; role of the potential field in the internal battery, be separated holes along a formed channel transmission to the cathode, while the electrons along the the PCBM receptor formed channel transmission to the negative electrode; holes and electrons were collected positive and negative electrodes forming a photovoltaic cell and optical voltage, thereby generating a photovoltaic effect.

Investigated the most important parameter for the performance of the organic solar battery comprising: a photoelectric conversion efficiency (Photovoltaic Convert Efficiency, PCE), open circuit voltage (Open Circuit Voltage, Voc), short circuit current (Short Circuit Current, Jsc), fill factor (fill factor, FF).
