CIGS pan­el factory

Rol­tec plans to launch the first thin-film photo­vol­ta­ic cell fact­ory in Poland in CIGS tech­no­logy in 2024. Tech­no­logy Read­i­ness Level at Rol­tec allowed for the devel­op­ment of large-scale pro­duc­tion of CIGS mod­ules, while main­tain­ing the highest stand­ards of qual­ity and repeatability.

High-effi­ciency photo­vol­ta­ic pan­els man­u­fac­tured in the Wrocław fact­ory will be our answer to the grow­ing demand of the renew­able energy mar­ket. We wish to pur­sue our Mis­sion to cre­ate a more sus­tain­able future. We believe that our busi­ness and invest­ment strategy will fit into the frame­work of the UN and EU Sus­tain­able Devel­op­ment Policy, and will remain the per­man­ent basis of our approach to devel­op­ment and oper­a­tion­al practices.

The Ger­man tech­no­logy (Solibro GmbH) acquired by, imple­men­ted and con­stantly improved at Rol­tec allows the com­mer­cial­iz­a­tion of a revolu­tion­ary product that will have a sig­ni­fic­ant advant­age in every aspect (price, speed and ease of install­a­tion, per­form­ance, war­ranty, aes­thet­ics) over sil­ic­on cells.4

The aes­thet­ic, frame­less Sol­voz pan­els will ensure energy pro­duc­tion in all light­ing con­di­tions, while guar­an­tee­ing a 15% high­er yield * per installed kWp.

CIGS tech­no­logy

Cop­per Indi­um Gal­li­um and Sel­en­ide, or CIGS, is a tech­no­logy of thin sol­ar cells (photo­vol­ta­ic) based on the depos­ition of four ele­ments (cop­per, indi­um, gal­li­um, sel­en­i­um) on any sub­strate. It is dis­tin­guished from many oth­er tech­no­lo­gies by the best spec­tral response, i.e. radi­ation absorp­tion. The great advant­age of our tech­no­logy is its high effi­ciency with the use of a small amount of material.

Dur­ab­il­ity, effect­ive work and aes­thet­ics make CIGS con­quer con­struc­tion mar­ket. Thin-film PV tech­no­lo­gies in prac­tice make use of photo­vol­ta­ics in urb­an space and land­scape archi­tec­ture (facade pan­els), cre­at­ing eco­lo­gic­al integ­rated solu­tions BIPV (Build­ing-Integ­rated Photo­vol­ta­ics) and BAPV (Build­ing-Attached Photovoltaics).

Due to the high absorp­tion of even low light and a low tem­per­at­ure coef­fi­cient, CIGS pan­els are char­ac­ter­ized by high effi­ciency even in dif­fi­cult con­di­tions. Non-tox­ic and safe cells are 98% recyc­lable. Sol­voz pan­els will be used primar­ily in large-scale energy pro­duc­tion for the needs of enter­prises (photo­vol­ta­ic farms).
