If by day, LED16 does not open, and transparency electrode 18 applies relevant voltage V
1The time, described controllable scattering layer 15 (liquid crystal) is not when opening scattering function, and the course of work of solar module 1 is with reference to shown in Figure 2, specific as follows: sunray a enters controllable scattering layer 15 from air, arrive light conversion layer 12, converted to longwave optical by the quantum dot of light conversion layer 12.Because the refractive index of air is generally 1.0, form the liquid-crystal refractive-index of controllable scattering layer 15 generally greater than 1, therefore, this longwave optical is in communication process, when being reflected this controllable scattering layer 15, total reflection phenomenon can occur, the formed zone of angle of total reflection conical region as shown in Figure 2.This longwave optical, for example light b, less than this angle of total reflection, namely fall into conical region with the incidence angle of propagating interface formation, can penetrate; Other light, for example light c, greater than this angle of total reflection, namely do not fall into conical region with the incidence angle of propagating interface formation, after the total reflection of interface, propagates between controllable scattering layer 15, might be utilized by solar cell 10.At this moment, do not fall into conical region and accounted for major part by the light that solar cell 10 utilizes, this assembly 1 is power generation mode, this be because, in theory, the direction of propagation forms the longwave optical of 2 π solid angles, and namely in Fig. 2, the light of episphere all can propagate into the interface of controllable scattering layer 15 and air, and the zone that the angle of total reflection forms is a very little solid angle zone.
Be still daytime, LED16 does not open, and transparency electrode 18 applies relevant voltage V
2The time, when controllable scattering layer 15 (liquid crystal) was opened scattering function, the course of work of solar module 1 is with reference to shown in Figure 3, specific as follows: sunray a entered controllable scattering layer 15 from air, arrive light conversion layer 12, converted to longwave optical by the quantum dot of light conversion layer 12.Because the refractive index of air is generally 1.0, form the liquid-crystal refractive-index of controllable scattering layer 15 generally also all greater than 1, therefore, this longwave optical is in communication process, when being reflected this controllable scattering layer 15, also total reflection phenomenon can occur, the formed zone of angle of total reflection conical region as shown in Figure 2.Need to prove, in said process, sunray a also can be scattered when entering controllable scattering layer 15.The longwave optical that the direction of propagation is random, wherein part can propagate in this controllable scattering layer 15, in the present embodiment one, this scattering layer 15 is liquid crystal, wherein the orientation of part light and liquid crystal is inconsistent, when this part light is propagated in liquid crystal, anisotropic structure has formed similar irreflexive structure, therefore, this part light is scattered in this layer 15, and the light that does not before fall into angle of total reflection zone becomes and falls into this regional probability and become greater than falling into before this regional light the probability that does not fall into this regional light.This be because, in theory, the direction of propagation forms the longwave optical of 2 π solid angles, and namely the light of episphere all can propagate into the interface of controllable scattering layer 15 and air, and the zone that the angle of total reflection forms is a very little solid angle zone, for instance, the light that does not before fall into angle of total reflection zone is 90%, and these a large amount of light become the probability that falls into this zonule, and fall into this regional light is 10% before, this a small amount of light becomes the probability of the light that does not fall into this zonule, and the former is greater than the latter.Continue with reference to shown in Figure 3, this longwave optical, for example light b ', still less than this angle of total reflection, namely fall into conical region with the incidence angle of propagating interface formation, can penetrate; Other light, for example light c ', become less than this angle of total reflection with the incidence angle of propagating interface formation, namely also falls into conical region, can penetrate.Need to prove, whether the scattering function of this controllable scattering layer 15 (liquid crystal) is opened, and only can make the micro-structurals in this layer 15 change, and does not affect the overall refractive index of this layer 15, thereby the solid angle zone at this angle of total reflection place can not change.To sum up, when controllable scattering layer 15 (liquid crystal) is opened scattering function, increased the probability of this longwave optical ejaculation solar module 1, at this moment, this assembly 1 is light illumination mode, can play a role in lighting in the greasy weather.
Can find out, when controllable scattering layer 15 (liquid crystal) is opened scattering function, longwave optical penetrates the probability increase of solar module 1, be when not opening with respect to the scattering function of controllable scattering layer 15 (liquid crystal), longwave optical penetrates the probability of solar module 1.
Need to prove, the controllable scattering layer 15 (liquid crystal) of foregoing description is not when opening scattering function, and the light that penetrates solar module 1 also plays a role in lighting, but this part light seldom, and this assembly 1 is still power generation mode; When controllable scattering layer 15 (liquid crystal) is opened scattering function, still have part light not penetrate solar module 1, this part light is still utilized by solar cell 10, but this part light seldom, and this assembly 1 is still light illumination mode.
If at night, LED16 opens, and transparency electrode 18 applies relevant voltage V
1The time, described controllable scattering layer 15 (liquid crystal) is not when opening scattering function, the course of work of solar module 1 is with reference to shown in Figure 4, specific as follows: LED light d injects light conversion layer 12 from the first transparent substrates 14, is converted to longwave optical by the quantum dot of light conversion layer 12.Because the refractive index of air is generally 1.0, form the liquid-crystal refractive-index of controllable scattering layer 15 generally also all greater than 1, therefore, this longwave optical is in communication process, when being reflected this controllable scattering layer 15, also total reflection phenomenon can occur, the formed zone of angle of total reflection conical region as shown in Figure 4.This longwave optical, for example light e, less than this angle of total reflection, namely fall into conical region with the incidence angle of propagating interface formation, can penetrate; Other light, for example light f, greater than this angle of total reflection, namely do not fall into conical region with the incidence angle of propagating interface formation, after the total reflection of interface, propagates between controllable scattering layer 15, might be utilized by solar cell 10.
Be still evening, LED16 opens, and transparency electrode 18 applies relevant voltage V
2The time, when controllable scattering layer 15 (liquid crystal) is opened scattering function, the course of work of solar module 1 is with reference to shown in Figure 5, specific as follows: LED light d injects light conversion layer 12 from the first transparent substrates 14, converted to longwave optical by the quantum dot of light conversion layer 12.Because the refractive index of air is generally 1.0, form the liquid-crystal refractive-index of controllable scattering layer 15 generally also all greater than 1, therefore, this longwave optical is in communication process, when being reflected this controllable scattering layer 15, also total reflection phenomenon can occur, the formed zone of angle of total reflection conical region as shown in Figure 5.The longwave optical that the direction of propagation is random, wherein part can propagate in this controllable scattering layer 15, in the present embodiment one, this scattering layer 15 is liquid crystal, wherein the orientation of part light and liquid crystal is inconsistent, when this part light is propagated in liquid crystal, anisotropic structure has formed similar irreflexive structure, therefore, this part light is scattered in this layer 15, and the light that does not before fall into angle of total reflection zone becomes and falls into this regional probability and become greater than falling into before this regional light the probability that does not fall into this regional light.This be because, in theory, the direction of propagation forms the longwave optical of 2 π solid angles, and namely the light of episphere all can propagate into the interface of controllable scattering layer 15 and air, and the zone that the angle of total reflection forms is a very little solid angle zone, for instance, the light that does not before fall into angle of total reflection zone is 90%, and these a large amount of light become the probability that falls into this zonule, and fall into this regional light is 10% before, this a small amount of light becomes the probability of the light that does not fall into this zonule, and the former is greater than the latter.Continue with reference to shown in Figure 5, this longwave optical, for example light e ', still less than this angle of total reflection, namely fall into conical region with the incidence angle of propagating interface formation, can penetrate; Other light, for example light f ', become less than this angle of total reflection with the incidence angle of propagating interface formation, namely also falls into conical region, can penetrate.Thereby, when controllable scattering layer 15 (liquid crystal) is opened scattering function, increased the probability of this longwave optical ejaculation solar module 1, at this moment, this assembly 1 is light illumination mode, can satisfy the purpose of night illumination.
Need to prove equally, the controllable scattering layer 15 (liquid crystal) of foregoing description is not when opening scattering function, the light (longwave optical that LED light or LED light are converted) that penetrates solar module 1 also plays a role in lighting, but this part light seldom, and this assembly 1 is still power generation mode; When controllable scattering layer 15 (liquid crystal) is opened scattering function, still have part light not penetrate solar module 1, this part light is still utilized by solar cell 10, but this part light seldom, and this assembly 1 is still light illumination mode.
The first adhesive layer 11 and the second adhesive layer 13 are printing opacity glue, EVA for example, and this is two-layer also can omit, and directly plays buffer action by air.
LED can be replaced by the solid-state light emitting elements such as fluorescent tube of OLED, elongated strip shaped, and light-emitting component gets final product in a word, but due to light source need be provided at night, thereby this light-emitting component does not comprise the sun.
The first transparent substrates 14 is also inessential condition, and as noted earlier, this substrate 14 provides the device of fixed L ED, and in the situation that controllable scattering layer 15 allows, LED can be arranged on around this layer 15.
Based on the effect of the light conversion layer 12 of aforementioned description, this layer 12 also can omit.Solar cell 10 directly absorbs the utilized wave band in sunlight or light-emitting component (LED).
