Description
Technical field
The present invention relates to solar photoelectric and utilize the field, particularly relate to the laminated composite solar battery of a kind of polymer solar battery and DSSC.
Background technology
French scientist Henri Becq μ erel transforms phenomenon in first observed in 1839 to photoelectricity, but but up to the appearance of the semiconductor solar cell of first practicality in 1954, the idea of " conversion of solar energy is become electric energy " just really becomes a reality.Though directly utilize the photovoltaic cell of photovoltaic effect the transformation efficiency of solar energy is wanted high several orders of magnitude compared with other non-direct conversion regime, but the installed capacity of global photovoltaic cell is very limited, and its main cause is that existing price based on inorganic silicon or semi-conductive photovoltaic cell is too expensive.Though through technological progress and the process modification of decades, its price has descended a lot, but exceeds the general acceptable scope of people, and the possibility that further significantly reduces exists hardly.At present the highest energy conversion efficiency of inorganic silicon photovoltaic cell (abbreviation photovoltaic cell) has reached 24%, based on the photovoltaic cell conversion efficiency of gallium arsenide semiconductor even reached 31%～32% (under the AM 1.5G condition).But creating conditions of they requires harshness, causes production cost very high, and can produce some hypertoxic materials in the process of making.In addition, shortcoming such as the non-pliability of inorganic photovoltaic cell and difficult processing has also limited the application process of its large tracts of landization.People begin to seek novel solar cell that can replace traditional structural.Wherein polymer solar battery and DSSC are exactly very promising two kinds, and these two kinds of solar cells all can be made on flexible substrate
1991, the Switzerland scientist
Utilize nanometer technology that the transformation efficiency in the DSSC is brought up to 7% first Deng the people.From then on, dye sensitized nano crystal salar battery (promptly
Battery) is born thereupon and is able to fast development.Up-to-date studies show that, based on
The efficient of the new dye sensitization solar battery of battery has reached 11%.DSSC mainly comprises work electrode, electrolyte and to electrode.Preparation one deck semiconductor porous film on conductive substrates, dye molecule is adsorbed on becomes work electrode then on the perforated membrane.To electrode generally is the electro-conductive glass that is coated with one deck platinum.Containing redox couple in the electrolyte, can be liquid, accurate solid-state or solid-state, and commonly used is liquid electrolyte.
Photovoltaic cell based on conjugated polymer, or title polymer solar battery, has the highest theoretical transformation efficient identical with the inorganic silicon photovoltaic cell, polymer solar battery but has the cheap large tracts of land manufacturing technology of in light weight, available wet method film forming (spin-coating, inkjet printing and silk screen printing), and can be made into advantages such as flexibility, extraordinary shape device, it in addition can realize all plastic and stronger light absorption density.The more important thing is,, can easily regulate and control the performance of device by MOLECULE DESIGN and synthesizing new semi-conducting polymer or organic molecule. based on these unique advantages, polymer solar battery becomes one of the most popular in recent years research field.But the present polymer solar battery efficient of developing is generally all also lower, and all below 5%, and performance is also unstable.The principal element that restricts its energy conversion efficiency is that the spectral response range and the sunlight terrestrial surface radiation spectrum of battery does not match etc.
More than the spectral response range of two kinds of solar cells be complementary to a certain extent, two kinds of batteries are combined, be prepared into the structure of a lamination, just can make the battery after synthetic have the spectral response range more wide in range than the both; Two kinds of solar cells are combined the effect that also can play mutual enhancing, and the battery of doing below can be for being made in the light that a top battery reflected back part is missed, and the battery of doing in the above can serve as a scattering layer for the following battery of doing; The both can use flexible substrate simultaneously, and manufacture craft is simple, makes laminated construction and can save a part of cost.
