This is suncurtain.

The com­pa­ny spe­cialis­es in devel­op­ing pho­to­volta­ic-active shad­ing sys­tems based on Organ­ic Pho­to­volta­ic (OPV) tech­nol­o­gy. To this end, the com­pa­ny pro­duces OPV cur­tain sys­tems for a wide range of applications.

The cen­tral idea is semi-trans­par­ent cur­tains that become small pow­er plants and pro­duce green elec­tric­i­ty. To this end, Sun­Cur­tain has devel­oped a clas­sic-look­ing ver­ti­cal blind whose slats con­sist of flex­i­ble, semi-trans­par­ent pho­to­volta­ic elements.

The cur­tain com­bines a wide range of pos­i­tive char­ac­ter­is­tics. The par­tial trans­paren­cy allows enough light into the room so that no arti­fi­cial light is need­ed even when the cur­tain is drawn. In addi­tion, only “cold” light reach­es the inside of the room. And last but not least, the cur­tain gen­er­ates elec­tric­i­ty. By man­u­fac­tur­ing the slats in a spe­cial coat­ing process, there is the pos­si­bil­i­ty of indi­vid­ual, cus­tomer-spe­cif­ic adap­ta­tion in design and format.

Frei nach ihren wünschen.

Farbe und Trans­parenz ist zwis­chen blau, grün, rot und grau wählbar. Die Ober­flächen kön­nen matt oder glänzend sein. Außer­dem bieten die Lamellen viel Gestal­tungs­frei­heit, wie Muster, Name oder Logo.

Der Vorhang bietet viel Poten­zial und neue Ansätze – wir evaluieren auch bish­erige Systeme.

Die hohe Lebens­dauer der Tech­nolo­gie wirkt sich ener­getisch langfristig auf das Gebäudesys­tem aus.

Die gewonnene Energie kann:

+ direkt genutzt wer­den
+ Zwis­chenge­spe­ichert wer­den
+ ins beste­hende Haus­netz einge­speist wer­den > Geräte im gesamten Stromkreis kön­nen ver­sorgt werden

Pro­to­typen zeigen erfol­gre­ich die Ver­wen­dung eines OPV-Moduls, als zu ver­schat­ten­des Ele­ment und demon­stri­eren vor allem das ver­steck­te Poten­zial eines jeden Fensters.

Frequently Asked Questions.

Sum­mer in par­tic­u­lar rais­es the urgent ques­tion of the right sun-screen­ing strat­e­gy. While every­one wants their home to be filled with nat­ur­al day­light, no one wants to bear the exces­sive­ly high inside tem­per­a­tures that occur on some sum­mer days as a result of no shad­ing. By devel­op­ing a cur­tain that not only pro­tects against the over­heat­ing caused by incom­ing solar radi­a­tion but also uses this solar ener­gy to pro­duce elec­tric­i­ty, the young com­pa­ny Sun­Cur­tain GmbH seeks to help boost ener­gy effi­cien­cy while simul­ta­ne­ous­ly increas­ing comfort.

The wide world of elec­tric­i­ty-pro­duc­ing curtains

When it comes to help­ing pro­tect the envi­ron­ment and con­tribut­ing to the change in ener­gy pol­i­cy, we need more than “just” improved build­ing effi­cien­cy. The behav­ior of build­ing res­i­dents, and a more holis­tic under­stand­ing of build­ings in gen­er­al, is open­ing up new prospects.

Large areas of glass on build­ings with inter­nal shad­ing usu­al­ly require arti­fi­cial light­ing and air-con­di­tion­ing, but Sun­Cur­tain offers a shad­ing sys­tem that doesn’t need arti­fi­cial light, as the cur­tain lets enough light in even when closed.

Sun­Cur­tain also unlocks an area of appli­ca­tion that has pre­vi­ous­ly been neglect­ed: Using win­dows as pow­er plants.

Cou­pled with this is the fact that OPV (gray ener­gy) pays itself off envi­ron­men­tal­ly in a few weeks, trans­porta­tion is fast and effi­cient, and every­thing is of “Made in Ger­many” quality.

Sun­Cur­tain gives every­one the chance to be part of the change in ener­gy pol­i­cy to help solve many dif­fer­ent prob­lems. All you need is a window.

The ben­e­fits of OPV

Sun­Cur­tain has man­aged to com­bine ben­e­fits such as a low weight, light trans­mit­tance, an inte­grat­ed UV fil­ter, pow­er gen­er­a­tion regard­less of the sun’s posi­tion, and scope for design free­dom in one cur­tain system.

Below are some oth­er Sun­Cur­tain benefits:

Reduces the effects of intense incom­ing solar radi­a­tion
+ Reduces UV and IR radi­a­tion, mean­ing bet­ter indoor cli­mate
Fil­ter­ing the warm light spec­trum cre­ates stim­u­lat­ing light­ing behind the cur­tain, result­ing in an alert work­ing envi­ron­ment
Still lets enough light through, mean­ing no arti­fi­cial lights need to be turned on when the cur­tain is closed
Also extracts ener­gy vir­tu­al­ly irre­spec­tive of the sun’s angle of incidence

Sun­Cur­tain devel­oped a sys­tem that absorbs the sun’s ener­gy and makes it avail­able to users, while still reduc­ing the side effects of intense incom­ing solar radi­a­tion. Organ­ic pho­to­voltaics has put itself front and cen­ter as the tech­nol­o­gy of choice for one such solu­tion. Incor­po­rat­ing ben­e­fits such as a low weight, light trans­mit­tance, an inte­grat­ed UV fil­ter, pow­er gen­er­a­tion regard­less of the sun’s posi­tion, and scope for design free­dom in one cur­tain sys­tem was a com­plete­ly new and some­what dis­rup­tive approach we want­ed to make a reality.

Our prod­uct impacts the entire building’s ener­gy, pro­vid­ing added val­ue in the form of pow­er sav­ings, a pleas­ant atmos­phere, and greater build­ing effi­cien­cy. The extract­ed ener­gy can also be inte­grat­ed into the elec­tron­ic infra­struc­ture, and direct­ly sup­ply sur­round­ing devices. This so-called direct feed-in means the legal frame­work is now also per­fect for this solu­tion – at least in Germany.

SunCurtain’s aim is to mean­ing­ful­ly help com­bat cli­mate change – for an inde­pen­dent, sus­tain­able world. It is also rev­o­lu­tion­iz­ing the shad­ing mar­ket and uncov­er­ing hid­den poten­tial. Its future prod­uct range is set to offer a wide range of solu­tions and replace exist­ing shad­ing systems.
