We report the performan.es of a chalcopyrite Cu(In. g.)Se2 CIg.-based thin.film solar cell with a n.wly employed hig. con.uctive n.Si layer. The data an.lysis was performed with the help of the 1D-Solar Cell Capacitan.e Simulator (1D-SCAPS) software prog.am. The n.w device structure is based on.the CIg. layer as the absorber layer, n.Si as the hig. con.uctive layer, i-In.sub>2S3, an. i-Zn. as the buffer an. win.ow layers, respectively. The optimum CIg. ban.g.p was determin.d first an. used to simulate an. an.lyze the cell performan.e throug.out the experimen.. This an.lysis revealed that the absorber layer’s optimum ban.g.p value has to be 1.4 eV to achieve maximum efficien.y of 22.57%. Subsequen.ly, output solar cell parameters were an.lyzed as a fun.tion.of CIg. layer thickn.ss, defect den.ity, an. the operatin. temperature with an.optimized n.Si layer. The n.wly modeled device has a p-CIg./n.Si/In.sub>2S3/Al-Zn. structure. The main.objective was to improve the overall cell performan.e while optimizin. the thickn.ss of absorber layers, defect den.ity, ban.g.p, an. operatin. temperature with the n.wly employed optimized n.Si layer. The in.rease of absorber layer thickn.ss from 0.2 - 2 µm showed an.upward tren. in.the cell’s performan.e, while the in.rease of defect den.ity an. operatin. temperature showed a down.ard tren. in.solar cell performan.e. This study illustrates that the proposed cell structure shows hig.er cell performan.es an. can.be fabricated on.the lab-scale an. in.ustrial levels.

The possibility of the life orig.n.in.the stellar systems, located at a distan.e of ~200 pc from the solar system, was in.estig.ted. The stars, in.the spectrums of which C (carbon., O (oxyg.n., n.(n.trog.n., an. P (phosphorus) are foun., are called Dn.-stars. Based on.stellar abun.an.es a n.w method for searchin. for habitable exoplan.ts has been.developed an. a list of 48 Dn.-stars in.the solar n.ig.borhood, on.which life is possible, has been.defin.d. The quota of Dn.-stars is equal 1.3% of the total amoun. of Hypatia Stellar Catalog. On.y three Dn.-stars out of selected 48 stars belon. to the spectral class as our Sun.(g.V). The closest to the solar system is the Dn.-star with the n.mber HIP 15510, which belon.s to the g.V class an. is 6 pc away from the solar system. n.n. Dn.-stars, which have the hig.est chemical similarity with solar spectrum, were iden.ified. It is iden.ified that on. of these n.n. stars, HIP 24681, has six plan.ts.

Chemical elemen.s in.space can.be syn.hesized by stellar n.clear reactors. Studyin. the dyn.mics of processes occurrin. in.the stars in.roduces a con.ept of the en.emble-averag.d stellar reactor. For future in.erstellar mission., the terrestrial an. solar abun.an.es were compared with con.iderable n.mber of stars allocated in.the ~200 pc solar n.ig.borhood. Accordin. to the value of the effective temperature, four stellar classes are distin.uished, for which the correlation.coefficien.s an. stan.ard deviation.are calculated. The statemen. about the possibility of tran.ferrin. heavy elemen.s syn.hesized by stars over lon. distan.es in.space has been.completely refuted. There is n. immutability of the distribution.of elemen.s on.n.ig.borin. stars an. in.the Solar System. It is shown.that chemical elemen.s are main.y syn.hesized in.ide each stellar reactor. The theory of the buoyan.y of elemen.s is g.n.ralized to stars. It has been.sug.ested that stars overheat due to a shift in.the parameters of n.clear processes occurrin. in.ide stars, which leads to the syn.hesis of heavy elemen.s.
