“…Notably, the researchers working in this field often neglect other types of ionizing radiation, such as X-rays and γ rays. While the influence of γ rays on Si solar cells was already explored, 18,19 to the best of our knowledge, there are still no reports on the γ radiation tolerance of perovskite solar cells. Herein we explore the impact of γ rays on the chemical composition, film morphology, crystal structure, and photovoltaic performance of the "triple-cation" Cs 0.15 MA 0.10 FA 0.75 Pb-(Br 0.17 I 0.83 ) 3 perovskite solar cells.…”

We report on the impact of γ radiation (0–500 Gy) on triple-cation Cs0.15MA0.10FA0.75Pb(Br0.17I0.83)3 perovskite solar cells. A set of experiments was designed to reveal the individual contributions of the hole-collecting bottom electrode, perovskite absorber, and electron transport layer (ETL) to the overall solar cell degradation under radiation exposure. We show that the glass/ITO/PEDOT:PSS hole-collecting electrode withstands a 500 Gy dose without any losses in the solar cell performance. In contrast, the perovskite absorber films and PC61BM ETL are very sensitive to γ rays, as can be concluded from the radiation-induced decay of the solar cell efficiency by ∼32–41%. Red shift of the perovskite emission bands and strong enhancement of the photoluminescence suggest that γ rays induce phase segregation of iodine-rich and bromine-rich domains, which represents the first reported example of the radiation-induced halide phase separation in perovskite films. The degradation pathway revealed here emphasizes the need for developing a new generation of metal halide absorbers and ETL materials with improved radiation stability to enable potential space applications of perovskite photovoltaics.

“…Düşük doz radyasyonuna maruz kalan güneş hücrelerinin I-V karakteristiklerinin ters besleme bölgesi karanlık akımındaki davranış, kGy mertebesinde radyasyonuna maruz kalan hücrelerde de gözlenen davranış ile benzerlik göstermektedir [18]. Doz miktarı artıkça karanlık akımdaki artış, tuzak enerji seviyelerinin artması sonucu azınlık yük taşıyıcılarının yarı ömürlerinin azalması ile ilişkilendirilmektedir [19,20]. Tablo 1'de ise c-Si hücrelerin radyasyon öncesi ve sonrası ölçülen yarı-logaritmik I-V eğrilerinin lineer kısmının eğiminden hesaplanan idealite faktörü değerleri verilmiştir.…”

“…Bu nedenle, azınlık yük taşıyıcılarının yaşam süreleri -indüklü kusurlara duyarlı olup, bu durum güneş hücrelerinin elektriksel özelliklerini olumsuz etkilemektedir [25]. Düşük doz miktarlarında bile gözlenen bu etki, yüksek doz miktarlarında daha da artarak güneş hücresinin çıkış performansını çok fazla etkilemektedir [19]. [19,27].…”

Çalışmada, ardışık düşük doz gama () ışınlarının mono-kristal Silisyum (c-Si) güneş hücresi üzerine etkisi incelendi. ışını kaynağı olarak 60Co kullanılmıştır. c-Si güneş hücresinin performansı, radyasyon öncesi ve sonrası karanlık ve AM1.5G ışık koşullarında alınan akım-voltaj (I-V), dışsal kuantum verimlilik (EQE), kapasitans-voltaj (C-V) ve iletkenlik-voltaj (G/-V) ölçümleri ile belirlenmiştir. Deneysel sonuçlar, radyasyona maruz kaldıktan sonra hücrelerin idealite faktörlerinin arttığını göstermektedir. Doz miktarı arttıkça kısa devre akımı (Isc) ve verim () değerleri azalırken, açık devre voltajı (Voc) ve doluluk faktörü (FF) değerleri ise yaklaşık sabit kalmaktadır. Dışsal kuantum verimlilik (EQE) ölçümleri, güneş hücresinde oluşan hasarın taban katmanında oluştuğu gösterirken, hücrede oluşan bu hasarın azınlık yük taşıyıcısı yarı ömründe oluşan azalma ile ilişkilendirilmektedir. Ayrıca, aygıt performansındaki değişim C-V ve G/-V ölçümleri ile de doğrulanmıştır. Deneysel sonuçlar, radyasyon öncesi ve sonrası karşılaştırılarak tartışılmıştır.

“…Also, Cahn [79] have studied the gamma irradiation damage in Si and Ge by atomic displacement model and compared with the experimental observations. Recently, Tobnaghi et al [80] and Ali et al [81] have reported the depletion of currents in solar cells with 60 Co gamma radiation due to the increase in density of defects states. Our previous studies indicated the role of gamma irradiation of p-type Si on the subsequent formation of porous Si under anodic etching [82].…”

We report a study of the role of material’s conductivity in determining the morphology of nanoparticles and nanostructures produced by ultrafast laser ablation of solids. Nanoparticles and textured surfaces formed by laser ablation display a wide variation in size and morphology depending on the material. In general, these qualities can be grouped as to material type, insulator, semiconductor, or metal; although each has many other different material properties that make it difficult to identify the critical material factor. In this report, we study these nanoparticle/ surface structural characteristics as a function of silicon (Si) resistivity, thus honing-in on this critical parameter and its effects. The results show variations in morphology, optical and non-linear properties of Si nanoparticles. The yield of colloidal Si nanoparticles increased with an increase in the conductivity of Si. Laser-induced periodic surface structures (LIPSS) formed on ablated substrates are also found to be sensitive to the initial conductivity of the material. Further, the laser ablation of Gamma-irradiated Si has been investigated to verify the influence of altered conductivity on the formation of Si nanoparticles. These observations are interpreted using the basic mechanisms of the laser ablation process in a liquid and its intricate relation with the initial density of states and thermal conductivities of the target material.
